I caught measles as a kid. I wasn't vaccinated. I don't know if my mother was antvax then, but she's definitely a crazy level, anti Vax (and many other conspiracy follower) theorist, now.

I thought I was going to die. Some 40 years later I remember it like it was yesterday, it was a horrific thing to do to a child, especially when meditation to ease it was available. I doubt I'll ever forgive my mother for that level of evil. She didn't care, either.
