Services were slow to process COVID vaccine exemptions, watchdog finds
Meghann Myers - Military Times

A Defense Department Inspector General review of the military’s COVID vaccine exemption process found that while the services largely followed policy when considering waivers, the Army and Air Force routinely overran deadlines, according to a report released Thursday.

The review also found a range of discharge types and reentry codes for service members involuntarily separated after vaccine refusal, leaving some troops with full benefits after being kicked out, while others received partial benefits.

“Prolonged delays in addressing requests for religious accommodations could impact a service member’s job placement and impede the command’s ability to make well-informed deployment and assignment choices,” said Defense Department Inspector General Robert Storch said in a release.

The review began in February 2022, prompted by IG hotline calls alleging that the services were rejecting exemption requests en masse. In June that year, then-Inspector General Sean O’Donnell sent Defense Secretary Lloyd Austin a memo with preliminary findings, including concerns that requests were being processed too quickly and without thorough review.

“The denial memorandums we reviewed generally did not reflect an individualized analysis, demonstrating that the Senior Military Official considered the full range of facts and circumstances relevant to the particular religious accommodation request,” O’Donnell said.

These concerns also prompted multiple lawsuits against DoD and the services, alleging that adjudication authorities were blanketly denying religious waiver requests. One case resulted in a judge halting the Air Force from discharging anyone for vaccine refusal after a waiver denial.

In 2023, after federal legislation required Austin to repeal the mandate in January, DOD settled two of the lawsuits by paying the complainants’ legal fees.

In the end, the IG found that the Army and Air Force actually took longer to approve requests than their policies required.

While the Army has a 90-day deadline for processing requests, the cases reviewed averaged 192 days to receive a decision. In the Air Force, 35 reviewed requests averaged 168 days to adjudication, though the deadline was 30 days.

When Austin announced in August 2021 that the COVID-19 vaccine would become required, vaccine exemptions in the military were rare. Most were for medical or administrative reasons, like an allergy, a pregnancy or someone preparing to separate from service, rather than the highly subjective religious exemption requests that flooded the services after the mandate came down.

Policy requires that “sincerely held religious beliefs” be accommodated as long as they do not impact “military readiness, unit cohesion, good order and discipline, or health and safety.”

The IG found that decision authorities weighed expert advice while considering the health risks of allowing someone to go unvaccinated, and that in the end, each case was examined individually before making a decision.

The fallout of the military’s COVID-19 vaccine mandate

But the “unprecedented number of requests” ? 16,000 from active duty troops as of January 2023 ? slowed down the adjudication process, the IG found.

At the same time, though the services followed DOD guidelines for discharges, those guidelines didn’t have uniform rules for using various types of discharges and reentry codes, which govern whether someone can re-join the military again at a later date.

“As a result, discharged service members experienced different impacts to their educational benefits and eligibility to reenlist in military service after discharge,” according to the report, as most vaccine refusals resulted in general discharges, which specifically denies GI bill benefits.

The IG recommended reviewing the exemption process to find ways to make it more efficient during high-volume periods, as well as creating standardized policy for discharges and reentry codes after vaccine refusal.

DOD accepted both recommendations and has efforts underway to address them, according to the report.

Problems After COVID-19 Vaccination More Prevalent Among Naturally Immune: Study
Prior infection identified as a potential predictor of adverse reactions.

By Zachary Stieber
3/14/2024

People who recovered from COVID-19 and received a COVID-19 shot were more likely to suffer adverse reactions, researchers in Europe are reporting.

Participants in the study were more likely to experience an adverse reaction after vaccination regardless of the type of shot, with one exception, the researchers found.

Across all vaccine brands, people with prior COVID-19 were 2.6 times as likely after dose one to suffer an adverse reaction, according to the new study. Such people are commonly known as having a type of protection known as natural immunity after recovery.

People with previous COVID-19 were also 1.25 times as likely after dose 2 to experience an adverse reaction.

The findings held true across all vaccine types following dose one.

Of the female participants who received the Pfizer-BioNTech vaccine, for instance, 82 percent who had COVID-19 previously experienced an adverse reaction after their first dose, compared to 59 percent of females who did not have prior COVID-19.

The only exception to the trend was among males who received a second AstraZeneca dose. The percentage of males who suffered an adverse reaction was higher, 33 percent to 24 percent, among those without a COVID-19 history.

“Participants who had a prior SARS-CoV-2 infection (confirmed with a positive test) experienced at least one adverse reaction more often after the 1st dose compared to participants who did not have prior COVID-19. This pattern was observed in both men and women and across vaccine brands,” Florence van Hunsel, an epidemiologist with the Netherlands Pharmacovigilance Centre Lareb, and her co-authors wrote.

There were only slightly higher odds of the naturally immune suffering an adverse reaction following receipt of a Pfizer or Moderna booster, the researchers also found.

The researchers performed what’s known as a cohort event monitoring study, following 29,387 participants as they received at least one dose of a COVID-19 vaccine. The participants live in a European country such as Belgium, France, or Slovakia.

Overall, three-quarters of the participants reported at least one adverse reaction, although some were minor such as injection site pain.

Adverse reactions described as serious were reported by 0.24 percent of people who received a first or second dose and 0.26 percent for people who received a booster. Different examples of serious reactions were not listed in the study.

Participants were only specifically asked to record a range of minor adverse reactions (ADRs). They could provide details of other reactions in free text form.

“The unsolicited events were manually assessed and coded, and the seriousness was classified based on international criteria,” researchers said.

The free text answers were not provided by researchers in the paper.

“The authors note, ‘In this manuscript, the focus was not on serious ADRs and adverse events of special interest.’” Yet, in their highlights section they state, “The percentage of serious ADRs in the study is low for 1st and 2nd vaccination and booster.”

Dr. Joel Wallskog, co-chair of the group React19, which advocates for people who were injured by vaccines, told The Epoch Times: “It is intellectually dishonest to set out to study minor adverse events after COVID-19 vaccination then make conclusions about the frequency of serious adverse events. They also fail to provide the free text data.” He added that the paper showed “yet another study that is in my opinion, deficient by design.”

Ms. Hunsel did not respond to a request for comment.

She and other researchers listed limitations in the paper, including how they did not provide data broken down by country.

The paper was published by the journal Vaccine on March 6.

The study was funded by the European Medicines Agency and the Dutch government.

No authors declared conflicts of interest.

Some previous papers have also found that people with prior COVID-19 infection had more adverse events following COVID-19 vaccination, including a 2021 paper from French researchers. A U.S. study identified prior COVID-19 as a predictor of the severity of side effects.

Some other studies have determined COVID-19 vaccines confer little or no benefit to people with a history of infection, including those who had received a primary series.

The U.S. Centers for Disease Control and Prevention still recommends people who recovered from COVID-19 receive a COVID-19 vaccine, although a number of other health authorities have stopped recommending the shot for people who have prior COVID-19.


Another New Study


In another new paper, South Korean researchers outlined how they found people were more likely to report certain adverse reactions after COVID-19 vaccination than after receipt of another vaccine.

The reporting of myocarditis, a form of heart inflammation, or pericarditis, a related condition, was nearly 20 times as high among children as the reporting odds following receipt of all other vaccines, the researchers found.

The reporting odds were also much higher for multisystem inflammatory syndrome or Kawasaki disease among adolescent COVID-19 recipients.

Researchers analyzed reports made to VigiBase, which is run by the World Health Organization.

“Based on our results, close monitoring for these rare but serious inflammatory reactions after COVID-19 vaccination among adolescents until definitive causal relationship can be established,” the researchers wrote.

The study was published by the Journal of Korean Medical Science in its March edition.

Limitations include VigiBase receiving reports of problems, with some reports going unconfirmed.

Funding came from the South Korean government. One author reported receiving grants from pharmaceutical companies, including Pfizer.

COVID-19 Vaccine Mandates Discouraged People From Getting Boosters and Other Vaccines: Study
A recent study found that vaccine mandates had no influence on COVID-19 vaccine uptake but did reduce voluntary vaccinations.

By Megan Redshaw
3/13/2024

Some U.S. states mandated COVID-19 vaccinations during the pandemic to increase vaccination numbers. Yet recent research shows these governmental restrictions had unintended negative consequences and no influence on COVID-19 vaccine uptake.

A study in PNAS found that state-level COVID-19 vaccine mandates did not impact vaccine adoption during the weeks before or after the mandates went into effect, suggesting vaccine mandates did not directly affect COVID-19 vaccination.

Additionally, compared to states that banned vaccine mandates through legislation, states that required COVID-19 vaccination experienced lower levels of subsequent boosters and reduced rates of voluntary flu vaccinations.

“The theory of psychological reactance serves as one longstanding explanation for why freedom restrictions in the form of governmental mandates cause people to reject the advocated behavior or otherwise have unintended consequences,” the study authors wrote.


Mandates Had No Influence on COVID-19 Vaccination Rates

To determine the impact that state COVID-19 vaccine mandates had on vaccination behavior, researchers examined epidemiological data from the Centers for Disease Control and Prevention (CDC) in 19 states, eight weeks before and after a mandate was imposed.

They also examined the uptake of subsequent vaccines, such as COVID-19 boosters and seasonal influenza vaccines, to see if restricting the freedom to choose whether or not to be vaccinated in the past affected the adoption of future voluntary vaccinations.

To get a baseline on attitudes toward COVID-19 vaccine mandates, researchers used data from the COVID States Project—a 50-state survey project supported by the National Science Foundation before the COVID-19 vaccine was made available to the public.

A group of scientific researchers launched the COVID States Project in March 2020 to help practitioners and governments make informed decisions, identify links between social behaviors and virus transmission, and measure the impact that regulation and messaging have on individual and community outcomes in a crisis.

The study research suggests that people’s acceptance of vaccine mandates depends on how they feel about the behavior before restrictions are implemented.

As part of their analysis, the researchers examined people who were already vaccinated before the eight-week sampling time frame and found no statistically significant difference in weekly vaccination rates before and after the mandate was imposed, nor were vaccination rates affected by baseline attitudes toward COVID-19 vaccine mandates.

When adjusting the sampling window before and after mandates to four and 16 weeks, researchers observed the same trends, suggesting that COVID-19 vaccination requirements were not associated with changes in vaccine adoption rates.


Unintended Negative Consequences for Boosters and Flu Vaccines

Using CDC data from November 2021—when boosters became available—through May 2022, researchers examined weekly differences in state-level vaccination rates of COVID-19 boosters in 19 states with vaccine mandates and 22 states that enacted legislation banning vaccination requirements.

Additionally, they looked at those who received a booster and those who were eligible but did not, as well as how state vaccination rates were impacted by legislation banning or mandating vaccinations. The study found COVID-19 booster uptake was lower in states that imposed vaccine requirements—with a greater discrepancy among states with lower vaccination numbers.

“This pattern is consistent with a tendency to respond negatively to COVID-19 vaccine mandates relative to bans, especially among states whose residents initially were less inclined toward getting vaccinated,” the researchers wrote.

The results were the same for flu vaccines. Researchers examined two CDC datasets on state-level flu vaccination rates among children and adults during the 2021–2022 flu season during the same period as the booster analysis.

They found adults in states with COVID-19 vaccine mandates were less likely to report receiving a flu shot than adults in states where mandates were banned. Likewise, children from states with vaccine mandates were less likely to have received a flu vaccine, and the difference was more significant among states with lower COVID-19 vaccination numbers.

The researchers said their findings support concerns expressed by scholars and practitioners that selective vaccine mandates can have harmful or unintended consequences for public health, and other research that found vaccine mandates don’t necessarily reduce the adoption of the required vaccine but do reduce voluntary vaccinations.

The authors of the paper concluded that legislation protecting an individual’s right to choose whether or not to receive a COVID-19 vaccine is actually more productive in encouraging related vaccinations.

Experts Warn: Vaccine Monitoring Crucial As COVID Variants Continue To Evolve
By The Francis Crick Institute
March 13, 2024

A recent study emphasizes the necessity of ongoing surveillance of COVID-19 variants and vaccine effectiveness, revealing that monovalent vaccines offer higher antibody levels against Omicron variants than bivalent vaccines. However, current vaccines may not prevent transmission of the newest strains, highlighting the need for continuous vaccine updates and the development of effective antibody treatments.

Scientists at the Francis Crick Institute and the National Institute for Health and Care Research Biomedical Research Centre at University College London Hospital stress the need for ongoing monitoring of new SARS-CoV-2 variants and the effectiveness of vaccines in response to the virus’s ongoing evolution.

Published as a research letter in The Lancet, their study compared the newer monovalent COVID vaccine, which specifically targets the XBB variant of Omicron (as recommended by the World Health Organisation), with older bivalent vaccines containing a mix of an Omicron variant and the original strain of COVID-19, which the UK deployed in Autumn 2023 before turning to monovalent vaccines.


Study Findings and Vaccine Comparison

The researchers found that both vaccines generated neutralizing antibodies against the most recent strain of Omicron, BA.2.86. However, the new monovalent vaccine generated higher levels of antibodies against a range of other Omicron variants.

The team collected blood and nasal mucosal samples both before and after a fifth dose vaccination from 71 participants of the Legacy study, a research collaboration between the Crick and the NIHR University College London Hospitals Biomedical Research Centre. They compared the antibody levels before and after vaccination.


Nasal Cavity Antibody Levels and Vaccine Efficacy

All 36 participants who received the bivalent vaccine and 17 who received the monovalent vaccine had boosted levels of antibodies against all variants tested, including the newest strain BA.2.86, which caused a wave of infection this winter. But those with the newer monovalent vaccine had 3.5x higher levels of antibodies against the XBB and BQ.1.1 strains after their booster vaccination.

Since the Omicron virus is highly transmissible and the virus replicates in the nose and throat, the researchers tested the levels of antibodies in the participants’ nasal cavity.

They found that the monovalent vaccine increased their ability to produce mucosal antibodies against most of the tested variants, whereas the bivalent vaccine didn’t provide a significant boost.

Neither vaccine increased neutralizing antibody levels in the nasal cavity against the newest variant, BA.2.86, suggesting that current vaccines may be less likely to stop transmission or prevent asymptomatic or mild illness, while still protecting against severe disease.

This highlights the importance of careful vaccine updates and continuing to complement a vaccination program with the development of antibody drugs that work against all variants, as some more vulnerable people don’t respond well to vaccines.


Expert Commentary and the Need for Future Strategies

Emma Wall, Senior Clinical Research Fellow at the Crick and Consultant in Infectious Diseases at UCLH, said: “The UK’s strategy to deploy stocks of older vaccines paid off last year, as both vaccines provided equal protection against the newest strain. However, ongoing monitoring is needed, as the virus is continuing to evolve, so vaccine-induced antibodies might not work so well in the future. In the long run, vaccines that are effective against all new variants and can block COVID-19 being transmitted from person to person are needed.”

David LV Bauer, Group Leader of the RNA Virus Replication Laboratory at the Crick, said: “The situation this winter could have been different if the newly emerged BA.2.86 and JN.1 variants were substantially distinct from older Omicron variants, but fortunately this wasn’t the case.

“Most new variants arise quicker than most clinical trials can produce data. But laboratory analysis can provide a detailed picture very quickly. Continued surveillance will help us stay on top of viral evolution.”

Startling Discovery: COVID-19 Virus Can Stay in the Body More Than a Year After Infection

By University of California - San Francisco
March 14, 2024

New research from UC San Francisco has found that COVID-19 can remain in the blood and tissue of some patients for over a year after infection, offering insights into the development of long COVID symptoms. The studies led by Michael Peluso reveal COVID antigens persisting in the blood for up to 14 months and in tissue samples for over two years, suggesting a possible link to long-term health effects.

The COVID-19 virus can persist in the blood and tissue of patients for more than a year after the acute phase of the illness has ended, according to new research from UC San Francisco that offers potential clues to why some people develop long COVID.

The scientists found pieces of SARS-CoV-2, referred to as COVID antigens, lingering in the blood up to 14 months after infection and for more than two years in tissue samples from people who had COVID.

“These two studies provide some of the strongest evidence so far that COVID antigens can persist in some people, even though we think they have normal immune responses,” said Michael Peluso, MD, an infectious disease researcher in the UCSF School of Medicine, who led both studies.

The findings were presented at the Conference on Retroviruses and Opportunistic Infections (CROI), which was held March 3 to 6, 2024, in Denver.


Evidence of long-term infection


Early in the pandemic, COVID-19 was thought to be a transient illness. But a growing number of patients, even those who had previously been healthy, continued having symptoms, such as, brain fog, digestive problems, and vascular issues, for months or even years.

The researchers looked at blood samples from 171 people who had been infected with COVID. Using an ultra-sensitive test for the COVID “spike” protein, which helps the virus break into human cells, the scientists found the virus was still present up to 14 months later in some people.

Among those who were hospitalized for COVID, the likelihood of detecting the COVID antigens was about twice as high as it was for those who were not. It was also higher for those who reported being sicker, but were not hospitalized.

“As a clinician, these associations convince me that we are on to something, because it makes sense that someone who had been sicker with COVID would have more antigen that can stick around,” Peluso said.


Virus persists for up to two years in tissue

Since the virus is believed to persist in the tissue reservoirs, the scientists turned to UCSF’s Long COVID Tissue Bank, which contains samples donated by patients with and without long COVID.

They detected portions of viral RNA for up to two years after infection, although there was no evidence that the person had become reinfected. They found it in the connective tissue where immune cells are located, suggesting that the viral fragments were causing the immune system to attack. In some of the samples, the researchers found that the virus could be active.

Peluso said more research is needed to determine whether the persistence of these fragments drives long COVID and such associated risks as heart attack and stroke.

But, based on these findings, Peluso’s team at UCSF is involved in multiple clinical trials that are testing whether monoclonal antibodies or antiviral drugs can remove the virus and improve the health of people with long COVID.

“There is a lot more work to be done, but I feel like we are making progress in really understanding the long-term consequences of this infection,” Peluso said.

Meeting: Conference on Retroviruses and Opportunistic Infections (CROI)

The studies were supported by funding from the PolyBio Research Foundation to support UCSF’s Long-Term Impact of Infection with Novel Coronavirus (LIINC) Clinical Core and a Merck Investigator Studies Program Grant. The National Institute of Health’s National Institute of Allergy and Infectious Diseases also provided funding (3R01AI1411003-03S1, R01AI158013 and K23AI134327, K23AI157875 and K24AI145806).

New Silent Surge Of COVID-19 Cases Involving SARS-CoV-2 Sub-Lineage KP.2 (JN.1.11.1.2) Starting In India Just Before he Holi Holidays

Waste water monitoring in certain cities in India including Bangalore are indicating a rise in COVID-19 infections while reports are emerging in various cities and villages in certain Northern states including Jodhpur in Rajasthan showing a rise of COVID-19 infections and pneumonia cases.

While India is submitting very little genomic sequences of tested positive COVID-19 individuals to GISAID…a global sharing platform, the Indian SARS-CoV-2 Genomic Consortium or INSACOG maintains a very detailed database of all genomic sequences that are conducted in the country.


The Indian government however is determined to not release too much data on the actual COVID-19 situation in India due to its enemies such as China, Pakistan and certain Western nations that are under the direct control of the WEF trying to cause disturbances to its economic, political and security issues. With India in an election year, the hopeless and filthy opposition lead by the Congress party that has ties with the WEF and also certain western powers that are trying to find ways to topple the Modi government that has managed to put India into the right track for economic growth in the last few years, it is expected that many filthy elements are trying to find fault with the Modi government.

The current India has every right to withhold any data to the COVID-19 situation and Indians have to be united to fight the COVID-19 scrouge that is not going away anytime soon be it in India or any other country in the world.

Sources in INSACOG revealed to us on conditions of anonymity that yes, India could be witnessing a new surge driven by the new KP.2 variant. This KP.2 variant is an offspring of the JN.1.11.1 ie JN.1.11.1.2 and spots the spikes mutati on R346T which makes even more transmissible.

covSPECTRUM
(note details on this platform, are not updated as the individuals behind it are either busy on twitter trying to get fame, or busy with media interviews with Fortune Well or busy criticizing Thailand Medical News on twitter!)

COVID-19 and genomic surveillance at various international airports around the world are showing a rise of Indian passengers with COVID-19 and most carrying the new KP.2 variant or the previous JN.1.11 variant. (Data from March 1 to March 10th at airports in United Kingdom, Japan, Hong Kong, Singapore and Australia.)

The debut of the original JN.1.11 variant was reported by Thailand Medical News in a COVID-19 News report in early January 2024.

https://www.thailandmedical.news/ne...surge-in-india-with-244-cases-detected-so-far

However, readers should not be alarmed as the JN.1 variants have been spawning thousands of newer sub-lineages with various mutations as it seems to have an even higher evolutionary rate and to date a few hundred JN.1 sub-lineages that have the right viral fitness and growth potential have been designated.

A few are listed here:


covSPECTRUM


Even the JN.1.11 variant has spawned numerous sub-lineages since including the current KP.2 sub-lineage.

Many of these newer sub-lineages just like the KP.2 variant, are more immune evasive and are more transmissible and in some cases, some cannot be detected by the current ATK test kits or even the PCR test unless the testing reagents are adjusted.

The good news is that most of all these new sub-lineages do not cause disease severity during the acute infection stages as they are evolving rather for viral persistence and are apt at disarming the host immune responses! Except for those in the vulnerable groups. (ie the aged, those with existing comorbidities, the obese, those that are immunocompromised, those with certain genetic makeups and also those that have been infected a few times in the past) that are still vulnerable for disease severity, the majority will not feel the impact during the initial infection phase.

However, viral persistence can lead to a variety of health issues and even possible fatal outcomes later but the good news is that such deaths will not be attributed to COVID-19 and hence governments around the world can continue to conceal the real threats of COVID-19 and promote the useless mRNA vaccines while continuing to assist the WEF’s agenda of depopulating the world!

The rise in various types of pneumonia cases in India and elsewhere should not be a cause of alarm, some are mycoplasma pneumonia infections caused by a bacteria and some are fungal based pneumonia…all of which are simply secondary opportunistic infections arising after infection with the newer JN.1 variants that cause immune dysregulation and even immunodeficiencies that leads to the rise of such opportunistic infections.

Indians in India instead of panicking, should learn to realize that COVId-19 is not going away and that they need to take their own preventive measures including masking, clean air strategies and social distancing. Those in the vulnerable groups need to take care of themselves and isolate when necessary. Above all, India is rich with a variety of herbal and phytochemicals products and locals should educate themselves and do due diligence to find ways to strengthen their immune systems in the right way and to use natural compounds as possible prophylactics. (There are tons of peer reviewed published studies online.)

With the coming Holi festivities and holidays coming in a weeks’ time in India, locals should take more precautions. A surge in COVID-19 cases is inevitable but there is no point making too much noise about it or blaming the local governments, rather people should be taking their own preventive actions.

The rise of COVID-19 cases in India does not warrant any panic as similar situations are currently occurring in various geolocations and countries around the world with the exception that some of these governments are even better at concealing the situation.

In reality, we are living in an era where SARS-CoV-2 is hyperendemic and we just have to understand the new normal where reinfections are the new norm and many will eventually die or suffer slowly! We have nothing in the arsenal to combat the SARS-CoV-2 virus and the Western conceived toxic vaccines are not going to help in anyway.

The Invisible Sculptor of COVID-19 Revealed
By University of California - Riverside
March 15, 2024

A team from the University of California, Riverside has made significant progress in understanding the SARS-CoV-2 virus by studying the M protein. Their research revealed how this protein helps the virus achieve its spherical shape, offering potential new avenues for viral intervention.

Researchers have uncovered how the M protein is key to the spherical structure of the SARS-CoV-2 virus, opening new paths for combating other pathogenic coronavirus outbreaks.

For centuries, coronaviruses have triggered health crises and economic challenges, with SARS-CoV-2, the coronavirus that spreads COVID-19, being a recent example. One small protein in SARS-CoV-2, the Membrane protein, or M protein, is the most abundant and plays a crucial role in how the virus acquires its spherical structure. Nonetheless, this protein’s properties are not well understood.


Innovative Research on M Protein

A research team led by a physicist at the University of California, Riverside, has devised a new method to make large quantities of M protein, and has characterized the protein’s physical interactions with the membrane — the envelope, or “skin,” — of the virus. The team’s theoretical modeling and simulations show how these interactions are likely contributing to the virus assembling itself.

The researchers report in their paper published today in Science Advances that when the M protein, which is adjacent to the spike protein on SARS-CoV-2, gets lodged in the membrane, it coaxes the membrane to curve by locally reducing the membrane thickness. This induction of curvature leads to SARS-CoV-2’s spherical shape.

“If we can better understand how the virus assembles itself, then, in principle, we can come up with ways to stop that process and control the virus’ spread,” said Thomas E. Kuhlman, an assistant professor of physics and astronomy, who led the research project. “M protein has previously resisted any kind of characterization because it is so hard to make.”

Kuhlman and his colleagues overcame this difficulty by using Escherichia coli bacteria as a “factory” to make the M protein in large numbers. Kuhlman explained that although E. coli can make copious amounts of M proteins, the proteins tend to clump together in the E. coli cells, eventually killing them. To circumvent this challenge, the researchers induced the E. coli cells to produce the protein Small Ubiquitin-related Modifier, or SUMO, along with the M protein.


Groundbreaking Techniques

“In our experiments, when E. coli makes M protein, it makes SUMO at the same time,” Kuhlman said. “The M protein fuses with the SUMO protein, which prevents the M proteins from sticking to one another. The SUMO protein is relatively easy to remove via another protein that simply cuts it off. The M protein is thus purified and separated from SUMO.”

The work provides fundamental insights into the mechanisms driving SARS-CoV-2 viral assembly.

“As M proteins are an integral component of other coronaviruses as well, our findings provide useful insights that can enhance our understanding and potentially enable interventions in viral formation not only in SARS-CoV-2 but also in other pathogenic coronaviruses,” Kuhlman said.


Future Directions


Next, the researchers plan to study the interactions of the M protein with other SARS-CoV-2 proteins to potentially disrupt these interactions with drugs.

Kuhlman was joined in the research by fellow-UCR physicists Roya Zandi and Umar Mohideen. Kuhlman was charged with making the M proteins. Mohideen, a distinguished professor of physics and astronomy, used atomic force microscopy and cryogenic electron microscopy to measure how the M protein interacts with the membrane. Zandi, an expert on virus assembly and a professor of physics and astronomy, developed simulations of how the M proteins interact with each other and with the membrane.

Other coauthors on the paper are Yuanzhong Zhang, Siyu Li, Michael Worcester, Sara Anbir, Pratyasha Mishra of UCR; and Joseph McTiernan, Michael E. Colvin and Ajay Gopinathan of UC Merced. Co-first authors Zhang and Anbir contributed equally to the work.

The research was supported by a grant from the University of California Office of the President to investigate how the COVID-19 virus assembles itself.

The research paper is titled “Synthesis, Insertion, and Characterization of SARS-CoV-2 Membrane Protein Within Lipid Bilayers.”

Please note - the word they use is LINKED. They are not saying CAUSATIVE. If they were (attributing the stomach issues to psych issues) I wouldn't have posted this study. I'm done with them saying long covid is 'all in your head'. That's not what this is saying. And of course someone who was in the hospital for covid and then has continuation of gastro symptoms for over a year is going to have a form of PTSD. so not surprised they are linked.... duh.. ;)

Digestive problems in 'long COVID' linked to psychological trauma, according research
by University of Oklahoma
March 15, 2024

Many people who were hospitalized with COVID-19 when the virus arrived in spring 2020 experienced a high rate of gastrointestinal problems and psychological trauma more than a year later, according to a recently published study led in Oklahoma by the University of Oklahoma College of Medicine. The research highlights the powerful relationship between the intestines and the brain, as well as a continued understanding of "long COVID" symptoms.

Gastroenterologist and Professor of Medicine William Tierney, M.D., led OU College of Medicine's participation in the study, which included hundreds of patients at academic health centers across North America. The study appears in the journal Clinical Gastroenterology and Hepatology.

"Gastroenterologists don't often ask our patients if they have had COVID-19, but this study provides clear evidence that prior COVID infection can lead to long-term gastrointestinal symptoms," Tierney said. "I think the main takeaway from this research is that primary care physicians and digestive disease specialists need to remember that COVID could be the trigger for a patient's long-term digestive symptoms. This notion can help provide an understanding of patients' symptoms and potentially avoid unnecessary testing."

In the study, more than 60% of participants met the criteria for DGBI, or Diseases of the Gut-Brain Interaction. DGBIs are believed to be caused by impaired communication between the brain and the gut (intestines) via the nervous system in both directions (brain to gut and gut to brain). With DGBIs, patients experience gastrointestinal symptoms, but tests don't identify inflammation or other intestinal diseases. The 60% rate of DGBIs in the study far exceeds what gastroenterologists see in a general population of patients.

The most common symptoms that patients experienced more than a year after their COVID-19 diagnosis were dyspepsia (upset stomach), irritable bowel syndrome, diarrhea, constipation and dysphasia (a sense of abnormal swallowing). When study participants were initially hospitalized with COVID-19, about half had similar digestive problems, but the fact that the symptoms have not only endured but have increased in frequency is significant, Tierney said.

In addition, the study revealed that more than 40% of participants met the criteria for Post-Traumatic Stress Disorder, or PTSD, which was a significant and unexpected finding, Tierney said. Notably, the research established a link between patients meeting the criteria for PTSD and experiencing long-term gastrointestinal symptoms.

"Obviously, the early months of the pandemic were very fearful and traumatic, but it is significant that patients were still experiencing trauma more than a year after they were hospitalized," he said. "However, because other symptoms of long COVID are neurological—such as brain fog and depression—it's not surprising that DGBIs are among the long-term symptoms. COVID-19 is primarily a respiratory illness, but other respiratory conditions such as the flu typically don't cause long-term gastrointestinal issues, so it's clear that COVID-19 is different."

The OU College of Medicine is one of 36 academic health centers in North America that formed the North American Alliance for the Study of Digestive Manifestations of COVID-19. The group has published several other research studies involving more than 1,500 patients.

Japanese Researchers Warn About Risks Associated With Blood Transfusions From COVID-19 mRNA Vaccinated Individuals
Nikhil Prasad Fact checked by:Thailand Medical News Team
Mar 16, 2024

The COVID-19 pandemic, declared by the World Health Organization (WHO) in 2020, has spurred unprecedented efforts to develop and deploy genetic vaccination programs worldwide. Genetic vaccines, particularly those utilizing mRNA technology, have emerged as powerful tools in combating SARS-CoV-2 infection. However, concerns have been raised regarding potential risks associated with blood transfusions involving individuals who have received COVID-19 mRNA vaccines. This COVID-19 News report delves into the intricacies of genetic vaccines, the risks they may pose in transfusion scenarios, and proposes detailed measures to address these concerns.


Understanding Genetic Vaccines and Mechanisms of Action
Genetic vaccines, including mRNA vaccines developed by leading pharmaceutical companies like Pfizer-BioNTech and Moderna, function by introducing genetic material encoding viral antigens, such as the spike protein of SARS-CoV-2, into host cells. This triggers an immune response that primes the body to recognize and combat the virus upon exposure. While these vaccines have demonstrated efficacy in preventing COVID-19 infection, emerging evidence suggests potential risks associated with their use, particularly regarding post-vaccination thrombotic events, cardiovascular complications, and systemic organ-related disorders.


Risks Associated with Blood Transfusions from Genetic Vaccine Recipients

Recent research conducted by institutions such as Asahikawa Medical University, Tokyo Medical University Hospital, MCL Corporation, Kyoto, Okamura Memorial Hospital, Tokyo University of Science, and Kokoro Medical Corporation in Japan has highlighted the risks associated with blood transfusions involving individuals who have received COVID-19 mRNA vaccines. These risks encompass a spectrum of potential complications, including but not limited to:

-Blood Abnormalities: Studies have reported cases of thrombocytopenia, thrombotic disorders, and abnormal red blood cell morphology in genetic vaccine recipients. Microscopic examination of blood samples from mRNA-vaccinated individuals has revealed anomalous findings, raising concerns about the potential toxicity of spike proteins and vaccine components.

-Immune Dysfunction: Genetic vaccines may lead to immune-related complications, including immune imprinting, antibody-dependent enhancement, and alterations in immunoglobulin class switching. These phenomena can impact the immune system's response to subsequent infections, potentially increasing susceptibility to certain pathogens or autoimmune reactions.

-Neurological Complications: There is growing evidence suggesting that the spike protein produced by genetic vaccines has neurotoxic properties and can cross the blood-brain barrier. This raises concerns about neurological complications in vaccine recipients and underscores the need for thorough monitoring and assessment.


Proposed Measures and Recommendations

In response to these identified risks, the following measures and recommendations are proposed to mitigate potential harm and ensure the safety of blood transfusions involving genetic vaccine recipients:

-Comprehensive Testing Protocols: Develop and implement rigorous testing protocols to assess the safety of blood products derived from genetic vaccine recipients. This includes screening for spike proteins, vaccine components, immune markers, and potential neurotoxicity indicators to identify any adverse effects.

-Regulatory Guidelines: Establish clear regulatory guidelines governing the collection, processing, storage, and transfusion of blood products from genetic vaccine recipients. These guidelines should outline strict protocols for donor screening, product labeling, and adverse event reporting to enhance safety and accountability.

-Long-Term Monitoring and Surveillance: Conduct long-term monitoring and surveillance studies to track the health outcomes and potential complications associated with blood transfusions from genetic vaccine recipients. This includes monitoring for thrombotic events, immune-related disorders, neurological manifestations, and other adverse reactions.

-Public Awareness and Education: Increase public awareness and education about the risks and benefits of genetic vaccines, blood transfusions, and immune-related disorders. This includes providing accurate information to healthcare professionals, patients, and the general public to facilitate informed decision-making and healthcare practices.

-Legislations - Laws and regulations need to be amended such that all sources of blood for transfusions are labelled as to whether they were from vaccinated or unvaccinated sources and also the recipients should have the rights to reject whatever types they do not feel comfortable with.


Conclusion
The risks associated with blood transfusions from COVID-19 mRNA vaccinated individuals are a significant concern that necessitates proactive measures and comprehensive strategies. By implementing robust testing protocols, regulatory guidelines, long-term monitoring, and public education initiatives, we can mitigate potential harm and ensure the safety and well-being of individuals receiving blood products from genetic vaccine recipients. Collaborative efforts among healthcare institutions, regulatory authorities, researchers, and the public are essential in addressing these challenges and fostering a culture of safety in transfusion medicine amid evolving vaccination strategies and infectious disease landscapes.

The study findings were published on a preprint server and are currently being peer reviewed.

 
In reality, we are living in an era where SARS-CoV-2 is hyperendemic and we just have to understand the new normal where reinfections are the new norm and many will eventually die or suffer slowly! We have nothing in the arsenal to combat the SARS-CoV-2 virus and the Western conceived toxic vaccines are not going to help in anyway.
Remember Uttar Pradesh and Ivermectin? Are they not using that anymore?

Researchers discover key metabolic process responsible for rapid immune responses
by Children's Hospital of Philadelphia
March 15, 2024

Researchers from Children's Hospital of Philadelphia (CHOP) identified a key metabolite in cells that helps direct immune responses and explains at a single cell level why immune cells that most efficiently recognize pathogens, vaccines, or diseased cells grow and divide faster than other cells.

The findings also indicate that a better understanding of this metabolite and its role in immune response could improve the design of immunotherapies and create longer-lived responses against different types of cancer as well as enhance vaccine strategies. The findings were published online by the journal Science Immunology in a paper titled "Single-cell NAD(H) levels predict clonal lymphocyte expansion dynamics."

Antigens are foreign substances that our immune system recognizes and responds to by producing more T and B cells. These cells each have unique receptors that recognize specific antigens and can respond appropriately, and they can "remember" and respond similarly when exposed to the same antigen again.

How well a T or B cell sees its antigen is known as its affinity. This fundamental concept of immunology is how vaccines work. When those T and B cells encounter a pathogen, the body needs the ones that recognize their antigen the best, with high affinity, to divide more quickly to produce more daughter cells and "attack" the invader.

However, the underlying mechanisms as to why high affinity immune cells respond more efficiently have remained a mystery for researchers. After seeing an antigen, the chemistry inside T and B cells needs to change to allow them to properly respond. The researchers in this study wanted to look at metabolism to understand what causes high affinity cells to know that they need to divide more quickly to respond appropriately.

"We wanted to see if specific metabolites were sensitive to T cell receptor affinity and controlled T cell expansion during immune responses," said senior study author Will Bailis, Ph.D., Assistant Professor of Pathology and Laboratory Medicine at CHOP and the Perelman School of Medicine of the University of Pennsylvania.

The researchers identified nicotinamide adenine dinucleotide (NAD) as a key, affinity-dependent component of T cell receptor metabolic reprogramming during the early stages of a T cell activation.

Using flow cytometry, the researchers could look at NAD in single cells immediately after activation and show how it dictates the number of times T cells can divide in the future. Therefore, researchers could essentially predict how T cells behave and how many times they divide based on how much NAD they started with.

Additionally, the researchers found that manipulating how much NAD a cell was allowed to make could control when that cell went from a resting state to wanting to divide, suggesting that the metabolite could be used to improve response in certain T cell-driven therapies or vaccines.

"We believe this work shows how single cell differences in metabolism are a key reason why similar cells sometimes display strikingly different behaviors and that this may provide insight into underlying processes that drive disease and dysfunction that cannot simply be explained by gene regulation or signaling," Bailis said.

"With more work, we also believe that this information could potentially be used to improve vaccine strategies and the response and durability of cell-based therapies used to treat cancer and other diseases."

UVA Health researchers have discovered a potential way to predict which patients with severe COVID-19 are likely to recover well and which are likely to suffer "long-haul" lung problems. That finding could help doctors better personalize treatments for individual patients.

UVA's new research also alleviates concerns that severe COVID-19 could trigger relentless, ongoing lung scarring akin to the chronic lung disease known as idiopathic pulmonary fibrosis, the researchers report. That type of continuing lung damage would mean that patients' ability to breathe would continue to worsen over time.

"We are excited to find that people with long-haul COVID have an immune system that is totally different from people who have lung scarring that doesn't stop," said researcher Catherine A. Bonham, MD, a pulmonary and critical care expert who serves as scientific director of UVA Health's Interstitial Lung Disease Program. "This offers hope that even patients with the worst COVID do not have progressive scarring of the lung that leads to death."


Long-haul COVID-19

Up to 30% of patients hospitalized with severe COVID-19 continue to suffer persistent symptoms months after recovering from the virus. Many of these patients develop lung scarring—some early on in their hospitalization and others within six months of their initial illness, prior research has found. Bonham and her collaborators wanted to understand better why this scarring occurs, to determine if it is similar to progressive pulmonary fibrosis and to see if there is a way to identify patients at risk.

To do this, the researchers followed 16 UVA Health patients who had survived severe COVID-19. Fourteen had been hospitalized and placed on a ventilator. All continued to have trouble breathing and suffered fatigue and abnormal lung function at their first outpatient checkup.

After six months, the researchers found that the patients could be divided into two groups: One group's lung health improved, prompting the researchers to label them "early resolvers," while the other group, dubbed "late resolvers," continued to suffer lung problems and pulmonary fibrosis.

Looking at blood samples taken before the patients' recovery began to diverge, the UVA team found that the late resolvers had significantly fewer immune cells, known as monocytes, circulating in their blood. These white blood cells play a critical role in our ability to fend off disease, and the cells were abnormally depleted in patients who continued to suffer lung problems compared both to those who recovered and healthy control subjects.

Further, the decrease in monocytes correlated with the severity of the patients' ongoing symptoms. That suggests that doctors may be able to use a simple blood test to identify patients likely to become long-haulers—and to improve their care.

"About half of the patients we examined still had lingering, bothersome symptoms and abnormal tests after six months," Bonham said. "We were able to detect differences in their blood from the first visit, with fewer blood monocytes mapping to lower lung function."

The researchers also wanted to determine if severe COVID-19 could cause progressive lung scarring, as in idiopathic pulmonary fibrosis. They found that the two conditions had very different effects on immune cells, suggesting that even when the symptoms were similar, the underlying causes were very different. This held true even in patients with the most persistent long-haul COVID-19 symptoms.

"Idiopathic pulmonary fibrosis is progressive and kills patients within three to five years," Bonham said. "It was a relief to see that all our COVID patients, even those with long-haul symptoms, were not similar."

Because of the small number of participants in UVA's study and because they were mostly male (for easier comparison with IPF, a disease that strikes mostly men), the researchers say larger, multi-center studies are needed to bear out the findings. But they are hopeful that their new discovery will provide doctors a useful tool to identify COVID-19 patients at risk for long-haul lung problems and help guide them to recovery.

"We are only beginning to understand the biology of how the immune system impacts pulmonary fibrosis," Bonham said. "My team and I were humbled and grateful to work with the outstanding patients who made this study possible."

The paper is published in the journal Frontiers in Immunology.

Aesculus-Hippocastanum (Horse Chestnut)

Aesculus hippocastanum L., commonly known as horse chestnut, has attracted attention due to its rich bioactive compound called beta-escin. This Herbs And Phytochemicals news report delves into the multifaceted antiviral potential of beta-escin from Aesculus hippocastanum, particularly its efficacy against coronaviruses like SARS-CoV-2.

Understanding the Threat: Respiratory Viruses and the Need for Broad-Spectrum Therapies
Respiratory viruses pose significant threats to public health, causing a range of illnesses from mild infections to severe respiratory distress syndromes. The traditional approach to managing such viruses involves supportive care and targeted antiviral therapies. However, the emergence of drug-resistant strains highlights the limitations of this approach.
The COVID-19 pandemic serves as a stark reminder of the importance of developing broad-spectrum antiviral therapies. Such treatments would not only address current viral threats but also prepare us for future pandemics. Beta-escin from Aesculus hippocastanum emerges as a potential candidate due to its diverse pharmacological properties.

Exploring Beta-Escin and Aesculus Hippocastanum: Anti-Inflammatory Effects and Mechanisms of Action
Beta-escin, a bioactive compound found in Aesculus hippocastanum, is renowned for its anti-inflammatory effects. Studies have shown that beta-escin modulates the NF-κB signaling pathway, a crucial regulator of inflammation and immune responses. This mechanism of action makes beta-escin an attractive candidate for combating viral infections that trigger excessive inflammation.
Furthermore, research has highlighted the virucidal and broad-spectrum antiviral properties of beta-escin against various enveloped viruses. These findings suggest that beta-escin could be a valuable asset in the fight against coronaviruses, including SARS-CoV-2.

Antiviral Activity Against Coronaviruses: Experimental Evidence and Mechanistic Insights
Recent studies have provided compelling evidence of beta-escin and Aesculus hippocastanum's antiviral activity against coronaviruses. Experimental assays demonstrated a concentration-dependent reduction in viral titers of coronaviruses such as SARS-CoV-2 and CCoV. Importantly, these effects were achieved without compromising cell viability, highlighting the specificity of beta-escin's antiviral action.
Further investigations into the mechanisms of action revealed that beta-escin and Aesculus hippocastanum interfere with early stages of the viral life cycle, particularly viral internalization. Time-of-addition assays elucidated the optimal timing for administering beta-escin to inhibit viral replication effectively. Additionally, these compounds exhibited prophylactic protection against coronavirus infections, underscoring their potential in preventing viral spread.

Modulating Host Immune Response: NF-κB Signaling and Cytokine Regulation
Apart from their direct antiviral effects, beta-escin and Aesculus hippocastanum play a pivotal role in modulating the host immune response. By targeting the NF-κB signaling pathway, these compounds inhibit viral replication and reduce the production of pro-inflammatory cytokines such as IL-6 and TNF-α. This dual action not only combats viral infections but also mitigates the inflammatory cascade associated with severe respiratory illnesses.

Clinical Implications and Future Directions
The comprehensive analysis of beta-escin from Aesculus hippocastanum reveals its immense potential as a broad-spectrum antiviral agent against coronaviruses, including the notorious SARS-CoV-2. The synergistic effects of beta-escin's antiviral activity, immunomodulation, and virucidal properties pave the way for novel therapeutic interventions in respiratory virus management.
Future research should focus on refining dosage regimens, assessing safety profiles in clinical settings, and exploring synergistic combinations with existing antiviral therapies. Collaborative efforts between researchers, clinicians, and pharmaceutical industries are essential to translating these findings into practical solutions for combating viral pandemics effectively.

Conclusion
Beta-escin from Aesculus hippocastanum holds tremendous promise as a versatile weapon against respiratory viruses, especially coronaviruses like SARS-CoV-2. Its ability to modulate the host immune response, inhibit viral replication, and directly target viral particles underscores its potential as a broad-spectrum antiviral agent. Continued research and development efforts are imperative to harnessing the full therapeutic potential of beta-escin in clinical practice, thereby addressing critical gaps in antiviral therapy and pandemic preparedness.

The study findings by the researchers from Universidad de Buenos Aires-Argentina were published in the peer reviewed journal: Scientific Reports (Nature).

What’s Happening Nicaragua? Pneumonia Cases Hits More Than 13,000 Cases So Far. Situation Similar To Brazil, Dengue, COVID-19, TB, Norovirus Rising!​

Thailand Medical News
Nikhil Prasad Fact checked by:Thailand Medical News Team Mar 20, 2024

Medical News: Nicaragua is currently grappling with a multifaceted health crisis, characterized by a surge in pneumonia cases, alongside escalating challenges posed by Dengue, COVID-19, Norovirus, and Tuberculosis (TB). This Medical News delves into each of these health issues, examining their impact, contributing factors, and the efforts underway to address them.
Medical-News-Nicaragua-Pneumonia-Cases-Dengue-COVID-19-TB-Norovirus.jpg

Even clinics in Nicaragua are overwhelmed at the moment!

Pneumonia Outbreak: A Growing Concern
The Nicaraguan Ministry of Health has raised alarms over the escalating number of pneumonia cases in the country. Since January 2024 to now, over 13,000 cases have been reported, with an average of 170 new cases daily. This trend mirrors the situation in Brazil, where pneumonia cases have also been on the rise.

The trajectory of pneumonia cases is concerning, with a sharp increase noted in January, reaching 4,207 cases within the first four weeks. Subsequent weeks saw 5,134 and 3,716 cases, respectively, totaling 13,057 cases within 77 days. While no deaths directly attributed to pneumonia have been reported in 2024, the preceding year witnessed 363 fatalities due to this respiratory illness.

In 2023, the most common cause of hospitalization in Nicaragua was pneumonia, while the most common cause of death was acute myocardial infarction.

The cause of the pneumonia is not being disclosed but local doctors insist that newer strains of the JN.1 variant is possible behind these surges.

There is literally no genomic surveillance in Nicaragua which makes it hard for scientist to figure out what is really happening there!

The government has a habit of concealing data and also lying about COVID-19 statistics:

https://confidencial.digital/englis...-to-claim-victory-over-covid-19-in-nicaragua/

In Nicaragua, 32,000 people died from Covid-19, but the regime only admits to 245 deaths

Dengue Fever
A Persistent Threat In addition to pneumonia, Nicaragua continues to battle Dengue fever, a mosquito-borne viral infection. The country witnessed a notable increase in suspected Dengue fever cases in 2023, with 10,127 hospitali-
zations due to fever suspected to be Dengue. The prevalence of Dengue adds to the burden on healthcare facilities and underscores the ongoing challenge of combating vector-borne diseases.

The Lingering Impact of COVID-19
The COVID-19 pandemic remains a significant concern in Nicaragua, albeit with fluctuating infection rates. While specific data for 2024 is not provided, the pandemic continues to strain healthcare resources and necessitates ongoing public health measures. Vaccination campaigns, testing initiatives, and healthcare infrastructure enhancements remain critical in managing the impact of COVID-19.

Vaccines And Cancer
Nicaragua had one of the high vaccination rates due to forced policies of the health authorities.

However, the latest reports show that cancers and rapidly progressing tumors are contributing to the hospitalization rates in the country.
Pneumonia Attacks in Nicaragua

Norovirus Resurgence
Nicaragua has also experienced a resurgence of Norovirus, a highly contagious virus causing gastroenteritis. The symptoms, including diarrhea, vomiting, and stomach pain, contribute to increased hospitalizations and add strain to healthcare services already stretched thin by multiple health crises.

Tuberculosis Challenges
Complexities in Diagnosis and Treatment The uptick in Tuberculosis (TB) cases further complicates Nicaragua's health landscape. TB, a bacterial infection primarily affecting the lungs, poses challenges in diagnosis, treatment, and prevention. Addressing TB requires comprehensive strategies, including enhanced diagnostic capabilities, treatment access, and public awareness campaigns.

Hospitals Overwhelmed Similar To Brazil
Almost all hospitals and clinics across the country are current overwhelmed and health authorities are in the midst of expanding Emergency Room facilities in many hospitals to cope with the growing number of cases.

Addressing the Crisis
Strategies and Interventions Efforts to address Nicaragua's health crisis encompass a range of strategies and interventions. These include:
-Genomic Surveillance
Need to set up proper genomic surveillance labs and increase sequencings of all reported cases.
-Vaccination Campaigns Increasing vaccination coverage against pneumonia, Dengue and other preventable diseases is paramount in reducing the disease burden and protecting vulnerable populations.
-Disease Surveillance: Strengthening disease surveillance systems enables timely detection, response, and containment of outbreaks, preventing further transmission and mitigating the impact on public health.
-Public Awareness Campaigns: Educating the public about preventive measures, symptoms recognition, and seeking timely medical care plays a crucial role in controlling disease spread and promoting health-seeking behavior.
Healthcare Infrastructure: Investing in healthcare infrastructure, including diagnostic facilities, treatment centers, and healthcare workforce training, enhances the capacity to manage complex health challenges effectively.
-Vector Control Measures: Implementing robust vector control measures, such as mosquito breeding site elimination and insecticide use, helps combat mosquito-borne diseases like Dengue and reduce transmission rates.
-Addressing Social Determinants: Addressing underlying social determinants of health, such as poverty, access to clean water and sanitation, and healthcare disparities, is vital in reducing health inequities and improving overall health outcomes.

Conclusion
Nicaragua's health crisis, marked by rising pneumonia cases, Dengue outbreaks, ongoing COVID-19 challenges, Norovirus resurgence, and TB complexities, demands comprehensive and coordinated responses. By implementing targeted interventions, strengthening healthcare systems, and addressing social determinants of health, Nicaragua can navigate these health challenges effectively and safeguard the well-being of its population. Collaborative efforts involving government agencies, healthcare providers, international organizations, and communities are essential in building resilience and promoting health equity in Nicaragua.

COVID-19 News: In a shocking revelation based on study findings, scientists at the prestigious University of Cambridge have unearthed a previously unknown facet of mRNA-based therapeutics, particularly in the context of mRNA vaccines like those developed to combat the COVID-19 pandemic.

This revelation covered in this COVID-19 News report comes at a crucial juncture in medical science, where the potentials of mRNA technology have been hailed as revolutionary yet accompanied by nuanced safety considerations that demand meticulous attention and further exploration.

Current COVID-19 mRNA vaccines generate unintended proteins that can
lead to unintended immune responses in up to one third of recipients! No
one knows what are the long term consequences of these proteins!

The study team discovered that misreading of therapeutic mRNAs by the cell’s decoding machinery can cause an unintended immune response in the body as a result of unintended proteins being produced! They have identified the sequence within the mRNA that causes this to occur and found a way to prevent ‘off-target’ immune responses to enable the safer design of future mRNA therapeutics. This discovered was made only in December 2023 which means that billions of people received the current mRNA vaccines which have yet to be modified to prevent this! Also, there are no studies to assess what effects these unintended proteins can have on the human hosts in the short or long term! (Note proteins can interfere with numerous enzymes, genes, cellular and signaling pathways etc in the humans and can cause various issues spanning from cancers to neurodegenerative issues etc! Simply discount it and making statements that there cause no ill effects without proper detailed studies is not right!

When contacted, the various mRNA vaccine manufacturers are refusing to comment or issue a statement on this study findings and the researchers from University of Cambridge insist that they rather not talk about it but rather focus on ways to make the future mRNA vaccines better and safer!

Decoding the Intricacies of mRNA and Its Impact on Vaccine Development
To comprehend the significance of this discovery, one must delve into the intricate workings of mRNA, commonly referred to as messenger ribonucleic acid. Essentially, mRNA serves as the genetic blueprint that guides cells in the body to produce specific proteins. This technology has been a game-changer, especially in vaccine development, as exemplified by the swift creation and deployment of mRNA-based vaccines against the SARS-CoV-2 virus, which causes COVID-19.

The pioneering work of biochemists such as Dr Katalin Karikó and immunologists like Dr Drew Weissman has been instrumental in harnessing the power of mRNA to prompt the human immune system to recognize and combat pathogens effectively. Their groundbreaking discoveries paved the way for the development of mRNA vaccines that have proven highly effective in controlling the spread of infectious diseases.

However, amidst the triumphs of mRNA technology, researchers at the University of Cambridge have delved into a lesser-known aspect - the potential for unintended immune responses triggered by mRNA therapeutics. Led by esteemed biochemist Professor Anne Willis and accomplished immunologist Dr James Thaventhiran from the Medical Research Council (MRC) Toxicology Unit, this research endeavor has brought to light a phenomenon that could influence the safety and efficacy of future mRNA-based treatments.

At the core of their discovery lies the 'slipping' of the cellular machinery responsible for decoding mRNA sequences. When faced with repeats of a chemical modification known as N1-methylpseudouridine, a common feature in mRNA therapeutics, the cellular machinery can 'slip,' leading to the production of unintended proteins. This unintended protein production, in turn, can trigger an immune response that was not originally intended or anticipated.

Navigating the Waters of Safety: Insights from Clinical Studies
To substantiate their findings, the research team conducted a comprehensive study involving individuals who had received the mRNA Pfizer vaccine against COVID-19. Their findings were both insightful and, in some ways, surprising.

Among the cohort of vaccinated individuals, approximately one-third exhibited an unintended immune response triggered by the mRNA vaccine. Importantly, despite this immune response, no adverse effects or health complications were reported, aligning with the robust safety profile established by extensive clinical trials and real-world data on COVID-19 mRNA vaccines.

Questions Now Being Asked About These Presence of These Unintended Proteins In The Human Host After Vaccination!
Many other scientists, researchers and doctors are now asking for more details about these unintended proteins including the list of these proteins and also as to whether any studies have been done to monitor the effects of these proteins on the human host over time. Proteins play key roles in various enzyme activities including their upregulation, downregulation and even dysregulation and also can bind to other key proteases or even affect signaling pathways, gene issues etc.

The fact that new proteins are being introduced into a human host should not be dismissed as something normal and statements such as not causing any ill-effects are very vague!

The scientist also commented that they have found solutions to make the next generation vaccines better but what about the billions who had been getting these vaccines before December 2023 when this discovery was made!

Engineering Solutions: Redesigning mRNA Sequences for Safety and Efficacy
Armed with these revelations, the University of Cambridge researchers embarked on a mission to devise strategies that could mitigate the risk of off-target immune responses in mRNA therapeutics. Their innovative approach involved redesigning mRNA sequences to circumvent the 'slipping' phenomenon observed during the decoding process. By fine-tuning the genetic sequences, they successfully achieved the intended protein production without triggering unintended immune reactions.

Conclusions
The discovery of the fact that unintended immune responses and unintended proteins are being generated by these current mRNA COVID-19 vaccines is actually an alarming discovery and even the researchers from Cambridge University under pressure to downplay the seriousness of their discovery used terms such as the need to find solutions to come up with second generation mRNA vaccines that can “prevent potentially harmful immune responses”!

More urgent studies are warranted to first identify and list all the unintended proteins that these current mRNA COVID-19 vaccines can cause and then detailed studies are needed to see what each and every one of these proteins can do in the human hosts.

Statements like no” ill effects” should be questioned and the vaccine manufacturers need to be more forthcoming with details and what they know.

The details about this discovery can be found here:

Unfortunately, most common people do not understand the findings of the study and even understand how unintended proteins being produced in a human host can have serious implications even for long term health issues!

BREAKING NEWS! New Sub-type Of H5N1 Avian Flu Has Possibly Emerged In Vietnam!​

Nikhil Prasad Fact checked by:Thailand Medical News Team Mar 23, 2024 34 minutes ago

H5N1 News: In the last few hours, Vietnam has been thrown into the spotlight as media outlets scramble to cover the possible emergence of a new subtype of H5N1 avian flu. The epicenter of this concerning development is Khanh Hoa province, where a 21-year-old university student has been confirmed as infected with the H5 avian flu virus. As health officials and the public grapple with the implications of this case, numerous questions remain unanswered, highlighting the urgency of understanding and addressing this evolving situation.

New Subtype Of H5N1 Avian Flu Has Possibly Emerged In Vietnam
The Patient's Journey: From Symptoms to Hospitalization


The unfolding saga began with the onset of symptoms in the young student on March 11. What initially appeared as mild discomfort quickly escalated, prompting the patient to seek medical attention. After a brief return home, during which time the virus may have spread within his household, the severity of his condition necessitated hospitalization. Currently, he remains in serious condition and isolated at the Provincial Hospital of Tropical Diseases in Khanh Hoa.

The patient is currently under mechanical ventilation and does not seem to be responding to any treatments including the usage of the antiviral Oseltamivir.

At the moment, Vietnamese health authorities have placed more than 214 individuals who had come into contact with the infected individual under isolation and are closely monitoring them.

According to sources from the provincial health department in Khanh Hoa, there are about 23 individuals in the group who are exhibiting symptoms of a respiratory infection.

The Pasteur Institute in Na Trang in Vietnam is currently overseeing all genomic testing and the institute so far has confirmed that a new subtype of H5N1 Avian Flu is involved in the initial case involving the university student.

Local experts claim that the new H5N1 subtype is originating from the virus branch 2.3.4.4b. (We do not have details to validate this as of yet.)

Media Frenzy and Official Responses
Vietnamese media outlets, including state-sponsored sources, have been abuzz with H5N1 News coverage of this alarming development. Reports detailing the patient's condition, the efforts to trace and test contacts, and the measures being taken by health authorities have dominated headlines.

Despite the lack of official statements from government health agencies, the credibility of these reports underscores the gravity of the situation.

Unraveling the Mystery: How Did the Student Contract the Virus?
One of the most pressing questions surrounding this case is the mode of transmission. The exact subtype of the H5 virus remains unidentified, adding complexity to the investigation. While previous cases involving H5N1 and H5N6 variants have been reported in neighboring countries like Cambodia, China and Laos, the specific origin of the virus in this instance remains a mystery. The absence of dead poultry in the vicinity further complicates efforts to pinpoint the source of exposure.

Response and Containment Efforts
In response to the confirmed case, health officials in Khanh Hoa have initiated comprehensive measures aimed at containment and prevention. Contact tracing, testing, and isolation protocols have been swiftly implemented to curb the potential spread of the virus. Additionally, disinfection procedures have been carried out in relevant locations, including the patient's dormitory at Nha Trang University.

Challenges and Unknowns
Despite these proactive measures, significant challenges persist. The inherent variability of the H5 virus, coupled with the potential for reassortment and emergence of new subtypes, underscores the need for vigilance and ongoing surveillance. The lack of clarity regarding the source of infection and the potential for human-to-human transmission further complicate the situation.

Global Concerns and Collaborative Efforts
Beyond Vietnam's borders, the emergence of this new H5 avian flu case has triggered international concern. Collaborative efforts involving organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) are crucial in monitoring and responding to such public health threats. Information sharing, research collaboration, and coordinated response strategies are paramount in mitigating the risks posed by infectious diseases like avian flu.

The Road Ahead: Seeking Answers and Preparedness
As the investigation into the H5 avian flu case in Vietnam unfolds, there is a collective sense of urgency to unravel the mysteries surrounding this incident. Key questions regarding the virus subtype, transmission dynamics, and potential implications for public health must be addressed through rigorous scientific inquiry and collaborative action.

In parallel, efforts to enhance preparedness and response capabilities at local, national, and global levels are imperative. Investments in surveillance systems, vaccine development, and public health infrastructure are essential pillars in safeguarding against the threat of emerging infectious diseases.

Conclusion: Navigating Uncertainty with Vigilance and Collaboration
The emergence of a new sub-type of H5 avian flu in Vietnam serves as a stark reminder of the ongoing challenges posed by infectious diseases. While uncertainties abound, proactive measures, scientific expertise, and international collaboration offer hope in navigating these turbulent times. As stakeholders across the health spectrum rally together, the collective goal remains clear: safeguarding public health and building resilient systems to confront the ever-evolving landscape of infectious diseases.

Update: We have received updates from local media that the Vietnamese government is issuing a directive to all local media to stop reporting on this emerging health issue. The health authorities have however conformed the emergence of the H5N1 outbreak and the WHO are also involved already.

The quieter it gets around the acute cases of (severe) Covid-19 disease, the more worried I become...​


Geert Vanden Bossche
Mar 22, 2024


A couple of months ago, a colleague was publicly attacking me and ridiculing me for predicting a major storm of severe Covid-19 (C-19) disease in highly C-19 vaccinated populations. While calling himself a vaccinologist, this person clearly doesn’t understand the interplay between the immune system and the evolutionary dynamics of SARS-CoV-2 (SC-2).

Although eager to learn from me at the outset of the mass vaccination campaign, this colleague now derogatorily refers to me as the veterinarian who, in support of his arguments, cites the effect of mass vaccination against Marek's disease. Nevertheless, that person knows all too well that I have always maintained that the example of Marek's disease vaccination is anything but applicable to the effect of mass vaccination during the current SC-2 pandemic. Instead of learning from my online course (Geert's Books and Lectures), this individual prefers to take the easy way out and simply dismisses my predictions as ‘irresponsible.’

Because I attach no importance to the prattle of those who deny vaccination-associated viral immune escape, I want to reiterate my predictions for the last time here. They remain unchanged even though the timeline has drastically changed compared to the initially projected timeline.

As I have repeatedly indicated, this change occurred because I did not take into account a hitherto unknown phenomenon at the time, namely that of vaccination-associated immune refocusing. This phenomenon is directly caused by the mechanism of action of mRNA vaccines (see my book: “The inescapable immune escape pandemic”; Geert's Books and Lectures), or indirectly as a result of breakthrough infections of individuals previously immunized with any C-19 vaccine.

My most recent insights into the immune response in vaccinated individuals are shared weekly with my online students. They are among the few who understand why I am rightly very concerned. I do not wish to overwhelm the many who, due to a lack of understanding of this complex matter, have meanwhile lost credibility in my predictions. Instead, I simply invite them to verify the following predictions. These are predictions of what will precede the anticipated tsunami in highly C-19 vaccinated countries:

-Infections with SC-2, normally typically presenting as acute self-limiting illnesses, are increasingly transitioning into chronic conditions. Cases of chronic illness due to SC-2 will increasingly constitute the bulk of the so-called ‘long Covid’ cases and almost exclusively occur in C-19 vaccinated individuals.
-More isolated cases of severe C-19 disease will contribute to the vaccine-associated excess deaths while C-19 hospitalization and death rates will remain relatively low.
-The concentration of SC-2 virus in wastewater (comprising all circulating variants) will also remain low.
-The JN.1. clade will comprise the dominant circulating lineages in highly C-19 vaccinated countries while many other subvariants are co-circulating at a much lower rate (e.g., BA.2.86, XBB.1.5, EG.5.1 and JN.1, JD.1.1, GE.1.) .
-More subdominant variants can emerge, but they won’t displace the JN.1 clade due to lack of higher transmissibility.
-The incidence of long Covid will steadily increase during this spring to then transition in a tsunami of antibody (Ab)-independent enhancement of severe C-19 disease. This mega-wave will thus occur even further outside the winter season.
-C-19 disease and mortality are not only no longer seasonal, they are also no longer age-dependent but mainly associated with the administration of (2 or more doses of) C-19 vaccines.
-High waves of severe C-19 disease will occur independently of each other, first in countries that used mRNA vaccines for mass vaccination.
-The unvaccinated are already becoming less frequently significantly ill, and this situation will only improve as the immune escape pandemic will evolve and escalate.

In Africa, little of this nefarious evolution will be noticeable because the vast majority of African countries did not have the 'privilege' of undergoing mass vaccination.

The increasing decline of acute, symptomatic infections leads our public health authorities and so-called experts to mistakenly believe that the worst part of the C-19 pandemic is behind us, and that the virus has now transitioned into endemicity thanks to herd immunity! They seem to ignore that the virus is still highly transmissible and evolving. As the majority of infections in highly C-19 vaccinated countries no longer follow the typically acute self-limiting course, but instead exhibit a more prolonged or even chronic nature, much of the attention previously focused on acute cases of (severe) C-19 disease has now shifted to other news items, which, while distressing, are still less threatening than the insidious immune escape pandemic.

For those interested in delving into the immunology behind the transition from acute symptomatic infection to a prolonged course of C-19 disease, the following explanation may be of interest:

The absence of herd immunity facilitates recurrent vaccine breakthrough infections (VBTIs) driven by new emerging variants with a steadily increasing level of infectiousness, leading to the formation of large virus-Ab complexes that are readily taken up by antigen-presenting cells (APCs) to activate cytotoxic T lymphocytes (CTLs). Enhanced clearance of virus-infected host cells by these CTLs promotes asymptomatic/subclinical viral shedding. This phenomenon is currently fueling sustained viral transmission and immune selection pressure on viral reproduction (as manifested by mutations in other viral proteins).

However, as JN.1 and its descendants change the interaction between the virus and APCs, including upper respiratory tract (URT)-resident dendritic cells (DCs), from virus internalization to virus adsorption, there is an increased demand for polyclonal non-neutralizing antibodies (PNNAbs) to effectively ‘neutralize’ viral virulence. While the formation of large viral-Ab complexes following VBTIs, facilitated by low-affinity Abs, enhances viral uptake by APCs rather than prompting the recall of PNNAbs, the concentration of the latter declines to suboptimal levels, exerting immune selection pressure on viral virulence.

This process sets the stage for the emergence of new variants that can broadly evade the virulence-inhibiting PNNAbs in highly C-19-vaccinated populations.

Understanding the evolutionary dynamics of the virus-Ab interactions during an immune escape pandemic in highly C-19 vaccinated populations is key to understanding the pivotal transition from acute self-limiting URT infection over subacute self-limiting pulmonary disease and, eventually, to chronic disease symptoms in distal organs (commonly referred to as 'long Covid').

The preceding explanations illustrate why I have consistently used the following one-liners to describe the direness of the situation:
"Societies in highly C-19-vaccinated countries will be caught off guard."
"Africa will win."
"We are currently witnessing the calm before the storm (tsunami)."
"When two dogs fight over a bone (alluding to the conflict between stakeholders and opponents of the mass vaccination program), the third (referring to the virus) will run away with it" or "Many parties are vying for control, but no one can master the virus."
"Scientists and public health authorities are no longer seeing the forest for the trees."
"It was highly predictable that the C-19 mass vaccination program could only lead to catastrophic consequences."
"Only Nature has the ability to restore the disrupted balance between the virus and immunity.”

While that colleague prefers not to engage in the more rigorous work but rather to 'check back in a couple of months', I reiterate that such a casual approach will undoubtedly fail to mitigate the crisis, as it will not provide sufficient time for any actions to be implemented aside from severe lockdowns.

Therefore, I believe it's imperative for someone to undertake a comprehensive effort to not only assess the immune pressure that highly C-19 vaccinated populations are currently exerting on viral virulence but also to communicate and elucidate this information, no matter how unpleasant, to the broader public:

I estimate the likelihood of a new variant emerging capable of evading the virulence-inhibiting effect of the PNNAbs to be 50% before the end of April 2024 and 99% before the end of June 2024.


Back in 2015, I designed some well-characterized neopeptide constructs capable of educating NK cells to recognize pathologically altered host cells upon intradermal administration. In my view, these constructs could serve numerous prophylactic and therapeutic purposes, including training NK cell-mediated innate immunity in C-19 vaccinees, thus offering them the same ‘training’ status as those who are unvaccinated. Previously, the unvaccinated had to endure symptoms and discomfort to attain this training status.

However, these pure, unadjuvanted constructs could provide such targeted training without inducing symptoms of C-19 disease or any side effects. However, even if I manage to find a team of scientists willing to collaborate on advancing this NK cell-enhancing platform, it's disheartening to realize that clinical trials would come far too late, preventing timely licensing of an adequate neopeptide. My intention has always been to make this technology available to all whose health could potentially benefit from it….

The sole alternative, not reliant on immunity, for fully vaccinated individuals to potentially diminish the risk of contracting enhanced severe C-19 disease is the prophylactic use of antivirals. These antivirals must be safe, broadly effective (i.e., against all circulating SC-2 variants), and would need to be made accessible in sufficient quantities at an affordable cost.

Last, I expect that this communication will likely prompt another call from my colleague, urging the broader public once again to 'stop listening to my predictions of doom and gloom that keep getting recycled and updated every six months'.

He travels the world to complain about backstabbing and the lack of an open and scientific debate. Sometimes, when I hear his criticism, I cannot help but think of the saying: 'The pot calling the kettle black…'

First of all, I wonder who the colleague was who publicly attacked him. Alexander? Malone?
In the comments of this sub-stack article, the commentators wonder if Geert knows this covid virus is a bio-weapon. But maybe that's not necessary since it is still a virus. And also Thailand News (TMN) is pointing to April 2024 and he does realize that this virus is a bio-weapon. TMN however, believes that there will begin a tsunami of death beginning in April more because the immune system will be overwhelmed with all sorts of disease, bacteria and virus, cancer etc. He also understands that the genius of this bioweapon is that it is slowly attacking the organs and the brain and heart.
TMN is alerting that Brazil and Argentina and Nicaragua hospital systems are already failing.

TMN sees the same thing as Geert in how many deaths there will be. So buckle up my friend. The road gets a lot rougher starting in a couple of weeks. Psalm 91 is a source of great comfort and peace for the crisis ahead.
