Amen, to both points. There's a pretty big difference between being an anti-vaxxer and not wanting to be too early on in the list. There's plenty of reasons to wait, but unless you have a health condition or allergy there's no good reason to abstain.
They don't even have any good reasons, and their logic is just straight fucked. Here's an argument that my mom had with pretty much the only anti-vaxxer in my immediate family (her other older, X'er son...sigh):
Mom: "Vaccines are the only reason we're rid of viruses like smallpox and polio."
AV: "Well, how do you know how bad it is? Have you met anyone with smallpox?"
Mom: *long, disbelieving pause* "No, because there were vaccines for it, and its effects are well-documented. I went to school with someone who had polio, and they were wheelchair bound and were in constant pain. I wouldn't wish that upon my worst enemy,"
AV: "I still think it's bullshit."
Mom: "Whatever."
(Side note: my folks are getting their shots on the same day I'm getting mine, though they have an earlier appointment)
The worst part about it is that anti-vaxxers tend to be vaccinated, so the only people they're hurting are their own kids. There are some states that allow minors to get vaccinations without informing their guardians, so some zoomers are going behind their idiot parents' backs and getting them anyway. That sort of thing needs to become a national policy.
