I mean, note that that transmission effect is dramatically reduced in the face of omicron. Back in August, after a booster it was about 53%. To me, who works regularly with seniors, the population at the highest risk from covid, that still seems like a lot.
The OTHER thing that bugs me about anti-vax propaganda, while I’m sitting here stewing about it, is that they grab hold of things like the identified risk of myocarditis post mRNA vaccine but fail to present the alternative. So, risk of myocarditis from vaccination in the highest risk group (men under forty) means that in a million doses of vaccine, ~40 men will get (and recover from) myocarditis–in all other groups the risk is much, much lower. However, in a million covid infections, 1600 will get myocarditis. So . . .
