Because vaccines work
@infobeautiful @wiebepaul wait: there's a vaccine against *chicken pox*?

@deborahh @infobeautiful @wiebepaul

yeah, that's news to me... but it was introduced widely in the US in 1995, and has been available since the early 1980s.

@pete @infobeautiful @wiebepaul wow, that's even more valuable if it saves adults from shingles later …
@deborahh @pete @infobeautiful @wiebepaul there's a different vaccine for shingles, but yeah
@catmisgivings @pete @infobeautiful @wiebepaul well, shingles happens in people who've already had chicken pox. Avoid chicken pox = avoid shingles, right?

@deborahh @pete @infobeautiful @wiebepaul what actually happened was, olds weren't getting exposed to chicken pox from their grands on the regular anymore, so their immunity waned leaving them vulnerable to shingles

That's why some countries decided not to vaccinate kids against chicken pox

Americans were holding "pox parties" to deliberately expose the kids to the chicken pox, though, and the authorities thought that was gross. So that's a big part of the reason why we vaccinate the kids

@catmisgivings @pete @infobeautiful @wiebepaul oh, I see!
I had shingles briefly, because I *did* have chicken pox as a kid. I read that the virus hides in nerve pathways until some stress makes it break out. I guess I am a very old, who had chicken pox 🤣🙃
