Yes, there's a lot of that going on, I believe. Many are angry because that serves to ameliorate their own sense of having been played for fools.
And some are simply frightened by what the future might hold for them, in terms of their long-term health.
Frightened seems about right. Does anyone else notice how the vaxxers don’t talk about the vax even among themselves? I’ve noticed around a lot of my acquaintances (not my friends, they are all purebloods) that if I mention anything about the covid shots, all they want to do is change the subject as quickly as possible. They’re scared, and don’t want to be reminded of it.
