I've often said that my grandmother was so grateful for all the childhood vaccines that came out during my mom's and my aunt's childhoods, or around that time (the Baby Boom era), because my grandmother really concretely saw how terrible some of those diseases were, with people in her generation actually contracting them in childhood, maybe even dying of them. But if you've really never seen them, it's pretty natural that they start to seem like something that barely even exists at all.
Like, I don't even know the different between typhus and typhoid, or what their symptoms are, or what you actually do to prevent them, or exactly how they're spread, or whether they've been eradicated in certain regions or whatever (or even whether there are any vaccines against them or whether or not I've personally received those vaccines in infancy!). I just barely have a vague sense that these are truly awful things that apparently exist in the world, probably relate to water contamination somehow, and may potentially come back in war zones or disaster zones. (Way to go, people who do ... something? ... to prevent those two!)

I feel like there needs to be a name for this. For now, "Those who do not learn from history are doomed to repeat it." is the most apt I think.
Happens constantly when you're essentially born on 3rd base. Maybe that's the proper name. Born on 3rd Base Syndrome.
