Literally HOW DO YOU BECOME IMMUNE TO THE BLACK PLAYUE

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.

Like everything else. You get it, and survive.

Also, plague did mutate, and morphed through history. When people got bitten by fleas it wasn't as deadly (still bad) as when transmission person to person (by coughing) became possible.

You become immune by surviving the disease. For some they will show no symptoms and it seems like they were always immune. Many will develop symptoms of varying severity and survive the infection. Now they have some immunity to the disease.

You either survive and gain immunity or die.
