CDC got caught lying about the vaccines, claiming they provided a benefit to those already infected. A message tons of people have been pushing - probably because of an attempt to discount natural immunity.
In fact, while the Pfizer trials excluded people with prior infections, 1,300 managed to get included anyway. Of that subset, the % infected was identical in both vaccine and placebo groups.
I've personally caught the CDC lying about masks. So I'm not surprised.
@pete I think that for an organization like a government apparatus, just brute-forcing the vaccine regiment is much cheaper than doing any form of analysis and differentiation. Like with the mask, it's a strategic lie to push the public into certain behavior.
