The further issue with a lot of this is that it was presented as having been validated as preventing spread from the beginning, which now Pfizer has stated did not transpire. It was pretty evident by early summer that it was not in fact doing that. It's a big piece of the narrative for forcing/mandating the vaccine and it's gone. Anyone questioning it immediately were lumped into the far right regardless of their reasons. It was bad medically and bad politically.
The reality is it was needed to help comfort and calm the populous, it provided some efficacy, but ultimately should have been a personal decision. There's 0 chance we won't see lawsuits for the foreseeable future and honestly i'm still on the side of personal choice.
You're right too, the vaccine never was on the level of "real" vaccines and we knew that, hence why they changed the legal definition to make it fit.
