Autistic people tend to travel together because we find similar social norms natural. I know a ton of old guys who were just weird in their era but would absolutely be diagnosed today.

There is no humane way to test a vaccine to the standard that anti vaxxers demand.

If the vaccine works, every vaccinated person released into the population is 1 person who cannot spread the disease. That means that the unvaccinated population will also get sick less often because they got exposed less often. That means that we need to isolate the vaccine and no vaccine groups from the general population to get reliable data. Except now we isolated our groups which may cause them to not get exposed to the disease. Ok, so that requires intentionally exposing 2 groups of people to a disease then withholding medical care from one of the groups. That is Tuskegee Syphilis Experiment levels of absolutely immoral to any sane person and would never ever pass an ethics review board.

So now you face a choice. Be the next Mengele, or stop all research into the concept of vaccination forever causing all harms globally that would have been prevented by working vaccines. Both would put you on the list of greatest villains in human history.

There is no 0 risk path forward. The solutions presented by anti vaxxers are worse than the current path, though there may be ways to improve.

And yes I know I'm reasoning against a cult position which is a total waste of my effort.
