okay, I’ll walk you through it but you are pretty bright so I think you’re being lazy…Fauci himself said with vaccination the country would reach herd immunity when we get to 75-85%vaccination.
"Dr. Fauci and his colleagues write that achieving classical herd immunity against SARS-CoV-2 is unlikely, due to a combination of factors that include features of the virus as well as current societal dynamics."
Achieving herd immunity thresholds have been less successful with respiratory viruses which continually mutate.
