Reply to comment by Linzold in [eli5] Black plaque was not exactly cured, how did it just disappear from Europe in 1353? by Linzold

You get it and live. It was not 100% fatal.

Additionally, if, say, 10% of the population is naturally immune, and you wipe out a third of the population overall with the disease, you end up with 15% of the survivors being naturally immune.
