For geeks:
Are cross reactive tcells the answer to why some populations are having less trouble?

T cells are a possible alternative protection to antibodies.
Cross reaction implies that T cells from one pathogen response can protect from a later one.
Cross reactive T cells seem to have helped with sars.
They last a decade.

Think cowpox. The antibodies to which protect from smallpox. It’s how the vaccination works.
Although we can’t do what Jenner did: inject live smallpox into his gardener to see if his vaccine worked. It did!

I do not think the Germans and South Koreans performance was better preparation. By the time either country recognised it , it was already endemic. The tests don’t work very well anyway.
Shutting a stable door. So what else is protecting some populations?
