That is part of the purpose behind the original anti vax campaign, to undermine a fundamentally long term accepted science. It’s a foot in the door for overturning anything “proven” by academia/science, in addition to being a learning course.

Just the other day, I was listening to a (maga) gentlemen tell me that he’s steering clear of Tylenol because it’s unsafe. He’ll only take acetaminophen. (I told him, he did not care. In his mind, they are two different meds).

So the original intent is working. The principle of the anti vax push is now imbued in American society. Canada too, now, sadly. I recently read about another measles outbreak up there.
