The unvaccinated survival rate for COVID-19 infection is 99.35% (https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios-archive/planning-scenarios-2020-09-10.pdf).
The vaccines increase that somewhere close to 100% by reducing the risk of infection significantly (~94% reduction in risk for asymptomatic infection and 97% reduction in risk for symptomatic infection) and reducing the severity of symptoms for those who actually do get infected. (https://www.cnbc.com/2021/03/11/pfizer-covid-vaccine-blocks-94percent-of-asymptomatic-infections-and-97percent-of-symptomatic-cases-in-israeli-study.html)
And 0.65% doesn’t seem like much, but 0.65% of 330 million Americans is 2,145,000. That’s simple math.
So, you’re assuming that all 330 million Americans will get the rona?
If not, why inflate your numbers?
But that includes 85 year-olds, the obese, diabetics, etc.
It is much, much lower for relatively healthy people (and kids).
Quite a few in the immediate know dispute those figures you cited vigorously.
