The degree of cognitive dissonance required to jump from "You can't make me take an unapproved vaccine!" to "I'll take horse de-wormer instead!" is frankly pretty astonishing. Interesting too, in a frightening sort of way.
All three of the vaccines in the US are approved.
@Pat Pfizer was just approved yesterday but the other two are still only available under the government's emergency use authorization. That's the case in the US anyway.
