Numbers are always relevant. You say this is a “small sample” of such deaths, but the article does not say that. It is conveniently silent about numbers.
If these are all such deaths then we are talking about 12-14 deaths out of 93,000,000 doses
If everyone in Germany died within 2 weeks of the vaccine then that’s a lot.
I suspect the actual number is somewhere between 40 and 93,000,000.
But we don’t know that number from the article, do we?
You also say “You can then apply this to the larger group of all reported deaths within 2 weeks after getting the jab”.
But you cannot apply the findings from a group of 40 to a larger population unless it is a statistically valid sample. We do not know how those 40 autopsies were chosen for him to review. We do not know whether they were chosen because there was some flag that raised particular questions about those deaths. If so, there would be an expectation that a larger percentage of those deaths would naturally be caused by the vaccine.
But we don’t know that from the article.
