Check the reply to the other user. Most things that I said there are relevant here.

What you described is why MAGA refuses to listen to experts re: the Covid vaccine and it’s specious logic at best.

By "maga" you mean the anti-vaxxers in Mexico, right?

What anti-vaxxers do, regardless of country, is to flip the fallacy around: from "authoriry said than its chrue lol" to "authoriry said than its false lmao". It's still a genetic* fallacy, i.e. they're still being irrational; you need to analyse the claim itself, not who said it.

If you know how vaccines are made, you don't need that appeal to authority on first place. You know that they're mostly safe, and it's overall better for society if you take the shot.

And, if you don't know how vaccines are made, this situation with vaccines is better handled through inductive reasoning. But then you don't get to say "I know it", like anti-vaxxers do; you weight the risk based on your incomplete information. (And then you get people correctly mocking you for being misinformed.)

*"genetic" because it refers to the origin of the claim, instead of the claim itself.

It also quickly backslides into “I don’t trust you because you’re an authority.”

Appeal to consequences is also a fallacy.
