on per his quotes, Fauci told the nation/world that 60% to 70% would do it. Though he admitted later that he wasn't telling the truth and was just making up numbers to what he felt the public would accept.
Then, according to the quotes, he told everyone that it would take 70% to 75%.
He claims that attacking him is akin to attacking science. Probably a lot of people believed him when he said 70% to 75% would get us to herd immunity.
Of course if as he originally stated, and common sense would dictate, that immunity from infection and recovery should be added to any effective vaccinations to get to herd immunity percentages we should already be there even if herd immunity required up to 98% immunity. Of course that would be based on a couple of assumptions... that the US covid deaths are at least close to reasonably accurate, and that the WHO studies at some 51 locations around the world that concluded that the infection fatality rate was .23% was also close to reasonably accurate. If more than 60% of our populace is already vaccinated (& the vaccines provide immunity... ha ha) then we would only need about 38% to 40% of the unvaccinated to have been infected and recovered, no?
If the # of infected = I and the Infection Fatality Rate is IFR the equation for figuring out the number of Americans who have been infected would be:
I * IFR = #Deaths
Solving for I we get:
I = #Deaths/IFR
Plugging in the numbers we get:
I = 827,206/.0023
I = 359,654,783
US population = 331,002,651

Solving for percent of US Population with Natural Immunity (%NI) we get:
%NI = I/population
% of US Population with Natural Immunity = 108.66%
108.66% of the non vaccinated have natural immunity we should be at herd immunity unless you or Fauci think that more than 100% of the population has to have immunity.
Of course, the WHO studies may not be perfectly accurate and the death toll numbers they've given us may not be totally accurate, but we should certainly be awfully close, no? Or at least anyone who believes in science should think so.
