I’ve now gotten old enough that the scar is gone(!!), but that was one of my go-tos with anti-vaxxers: I’d show them the scar on my arm and ask them if they had one like it. No? Oh, that’s right: because my generation all got the vaccine; now smallpox is eradicated and no one has to get the vaccine anymore!
If you get your kids vaccinated, maybe your grandchildren won’t have to be, or at least not for as many diseases.
