Even if they are working somewhat, even if not as perfectly as hoped?
The shots were approved to PREVENT COVID19. The FDA's stated VE threshold is 50%.
They worked to spec for a while. Not anymore.
Let's say the shots DO help keep people out of the hospital. While that's a positive product feature, if it's failing to perform its PRIMARY function, then a) revoke its approval, b) perform clinical trials on hospitalization, and c) obtain approval on THAT basis.
I want my medicinal compounds to do what they're formulated to do.
