Very little. I think I maybe convinced two people to examine their idiotic prejudices after trying gently with perhaps fifty, and I've no idea whether they got uh Red Pilled or whatever (?). But here's the thing: There are no points awarded for being Right in this game. You or I will die just as fast as anyone else (statistically, maybe you or I have a particular genetic resistance, but you get the idea) when the next, radically more virulent virus comes along. Again, this isn't a moral question, it's purely practical. Viruses do not have a conception of "should" and if they could laugh they'd laugh at Virtue. The ONLY practical thing which can be done (beyond the Herculean efforts of our Scientists) is attempting to break the waves of ignorance.
Consider: If you, and I, and everyone else convinced *one* person who was previously vaccine-hesitant early on, this thing might never have become endemic.
As ever, being on the "right side of History" (or whatever) isn't easy. If it was easy, everyone would be doing it.
