The immune system is designed to lower IFR as well. Only better when we look at low vax to high vax areas of comparable sizes.
Funny you picked Arkansas. They have 8 deaths, not 20 for comparable population size to SF. Less than half for a population that is half as vax'd as SF if you want to link anything.
Ok. 0 in SF compared to 8 daily deaths in Arkansas. Or 20 in Arkansas versus 0 in SF, depending on which population size is your default.
Sounds like the mask + vaccine plan has fewer covid deaths than the no mask + no vaccine plan.
Any luck finding a highly vaccinated city with high daily deaths?
