No friendships survived. My own family barely talks to me now. I went hard on the vax- almost everyone I know took it so they all hate me.
This is the narcissistic mistake of the well-intentioned. Just as the Gamma who erroneously believes that the power and purity of his attraction to a woman will make him attractive to her, the informed assumes that those he tries to save, but fails to convince, will be grateful to him and appreciative of his efforts when they eventually realize that he was right all along.
This never happens. Humanity is an ungrateful species. The average individual is more likely to hate you for being right than appreciate you for caring enough for trying to save them. In fact, they are more likely to blame you for not trying hard enough, no matter how hard you actually tried, because your lack of success in saving them is sufficient proof of your lack of effort.
This doesn’t mean that you shouldn’t do your best to warn your friends and family of future dangers. It means that you should warn them once, twice at most, and be willing to answer any questions that they might have for you, but do no more than that.
Most people are incapable of learning, or changing their minds, on the basis of information. Accept that and accept them how they are and for what they are. As soon as it’s clear that they’re not going to listen to you, leave them to their fate and thereby preserve the relationship. Because, in the end, you can’t save anyone who doesn’t want to be saved.
If Jesus Christ can’t, you certainly won’t be able to.
