That would be smallpox. I went to Europe in 1971 and got the booster shot that year. The last year that it was given.

Not to hijack the topic, but I wonder -- what did kids of the 50s/60s get to protect them from smallpox? You'd think I'd know (having grown up in that era), but it just wasn't something I had any attention on at the time.

Weird thing is that since 1971 no children in the US have received a vaccine for smallpox.

I read somewhere that the vaccine lasts for about 10 years, that is why it was necessary to get booster shots if you were visiting a foreign country.

If smallpox raised its nasty head again, our country would be in for a world of hurt.
