New Trump vaccine policy limits access to COVID shots to those 65+ or with demonstrated health issues; likely blocks access to others

I appreciate the attempt to backtrack from the claim of "There has never been any evidence" to nit-picking about the types of analysis used on the evidence which very much does exist.

It's interesting that you classify valid concerns with study methodology to be "nit-picking". The quality of the evidence is certainly relevant to any study's usefulness and validity. Just because someone did a "study" doesn't mean that it proves anything. I posted an article that explains in detail why a test-negative control analysis is not exactly gold-standard evidence (which you dutifully ignored).

The study you referenced only included people who sought medical care. What about all the people who get boosted and get COVID anyway? There are far more of them than those who seek medical care, yet they are not included in the study. In another discussion about myocarditis, I created a graphic to illustrate how rates can be severely skewed using this methodology. It applies to any situation where we only examine people who seek medical care.



When the denominator is wrong (as it almost always is in test-negative control studies), the results can be wildly inaccurate, as the above graphic vividly illustrates.

If it makes you feel better, I'll amend my earlier statement to say that there has never been any quality evidence that boosting young, healthy people provides any real benefit.
