somewhere between phase I and II - I am not even sure phase I safety standards are established for some populations which are getting this. so few people have any background around the fda’s approval process. I came at it from the financial side but parsed a lot of studies (mainly nda-related). what is being said by authorities about these vaccines would be actionable misinformation under other circumstances.

Phases 1 & 2 included healthy people between 18-55 years old. Everyone else excluded including pregnant women. Meanwhile, that does not apply to the mass vaccination of the public. Old, unhealthy and pregnant women? No problem, step right up and get your jab. Kids too. We are now in Phase 3 but technically not done with Phases 1/2 because they all run for two years. Then there is Phase 4 which is kind of a mute point.
