Stats by counties with known political demographics. That’s the metric driving the stated outcome.
Well most of the counties across America are Red. County populations vary wildly. The rate of herd immunity is a function of density. Flu spread and migration was not uniform. And the “pandemic” was pretty much over prior to the rollout of the vax.
A specious study as far as I’m concerned.
See the link to the Vinay Prasad video in my #15 above.
Vinay has also written about this “study” on Twitter, on his Substack, and in a professional journal.
