That's the second person I've seen acting like the COVID vaccines weren't put through the testing and approval process. Is this some new talking point?
The standard approval process for a new drug takes years. The vaccines have been approved under Emergency Use Authorizations after extensive testing. The fact that the standard process was bypassed is what gives rise to the talking point. I would say the fact that 55+ million Americans have been vaccinated with essentially no ill effects is pretty strong evidence.
