Last week one of the medical professionals, not Fauci, but a woman doctor, said that because there are no plans to vaccinate children, 95% of adults will have to be vaccinated in order to achieve herd immunity.
Right now in red states it's the macho thing to not wear a mask and not get vaccinated. Recently Trump repeated the baseless claim that vaccinations cause autism. The horrendous divide in this country is going to make it very hard to defeat the virus.
