I seriously doubt you even understand this dynamic. And Fauci is just bloviating about "viral dynamics"And if you put yourself in an environment in which you have a high level of viral dynamics and a very low level of vaccine, you might want to go the extra step and say, "When I'm in that area where there's a considerable degree of viral circulation, I might want to go the extra mile to be cautious enough to make sure that I get the extra added level of protection. Even though the vaccines themselves are highly effective."
that is a term of internal infections (in the host) nothing to do with transmissions or acquiring infection itself
when are you giving up the mask? like never ROFL
