Can't argue with that, although it is redundant based upon current standards. I'm sure most of this is a lot of pandering to their political base (which the majority of antivaxers probably belong to).
In the current climate, even if they are redundant, I like the idea of more guardrails rather than fewer. You have to believe that the pressure that's going to be placed on the FDA to get a vaccine out in late October is going to be ferocious. That may include even bootlegging the Russian vaccine in some fashion. Obviously that would require an end-run around current FDA rules but that's not stopped the current Administration in any other context. I'm not 100% convinced that the current head of the FDA has the backbone or the stomach for drawing lines and saying no. He could also be replaced with a stooge who is more willing to be compliant with what Trump wants.
