I agree with
@Beth Gallagher in that there is no point in ridiculing or otherwise putting someone down who listened to a different expert than you did. In 2020, the prevailing voice for the medical community, the only one that was allowed a voice, was that everyone should line up for the mRNA vaccination. While I, and roughly 20% of the population, questioned that advice, it could be considered reasonable to go along with it at that time, particularly given that many people were not allowed to work, visit family, or even travel without the vaccination.
I also believe that those who were in the minority in 2020, and the experts whose voices were difficult to find then, have since been proven right, but I wouldn't expect the mRNA-pushers in 2020 to admit, in 2026, that they were wrong, and those who received the vaccines and the boosters can be expected to either continue to insist they were right in having done so, or be angry about it, and most of us don't enjoy being angry.
While it seems clear today, to those who are willing to look, that the mRNA COVID vaccines were not a good idea, those who got them can't undo that, so they can deal with that however they wish. It makes sense to warn someone when you see danger, but it doesn't make sense to ridicule someone, after the fact, for listening to their doctor and the man whom the federal government, under both Trump and Biden, appointed as the spokesperson for medical science. I'm happy that I didn't do it, but it has to be considered reasonable to have listened to them at the time.
