One of the reasons I've heard people give for not getting vaccinated, is that the Pfizer approval is "for emergency use only".
That changed today. Pfizer now has full FDA approval.
Of course, people will still use the batshit crazy excuses, such as the fear of being microchipped, or the 5G fantasy (whatever that is). And Trump got booed for telling people at his rally to get vaccinated. Or the fact that the vaccine was developed very quickly. But full FDA approval is the "gold standard" for medications.
