When I was a kid the chicken pox vaccine was still pretty new. I remember hearing parents talking about it, and remember a few of them saying that it was only X% effective (don’t remember what that percentage was off the top of my head)

At the time, it seemed like every other children’s show had a chicken pox episode with one or more of the characters getting chicken pox, their parents talking about having a chicken pox party to get their kids infected, etc. it kind of seemed like it was almost inevitable that either I’d get chicken pox at some point or a lot of kids I knew would.

But I, and most of the kids I went to school with, did end up getting the vaccine, and very few kids in my school ever ended up with chickenpox. I can probably just about count the number of cases on my fingers in a school with hundreds of kids.

So vaccines work.

Funny story though, at one point in my childhood I got sick and ended up getting a prescription for amoxicillin. I started breaking out in sort of a rash/hives, and for a while they thought it might be chicken pox.

Turns out I’m actually just allergic to amoxicillin.

And then to make things even weirder, my sister gets a similar reaction from the azithromycin I usually got instead.
