That's immunity.

Auto in auto-immunity is not the "auto" from "automatic" but the ancient Greek "auto-" meaning "self-".

So, auto-immunity is like self-fighting (fighting yourself). You don't want that.

(which is also from the Greek auto meaning self)

I think GP meant it's not shorthand for automatic

Yep. Automatic, autonomous, all are from auto (self), automatic being "doing by itself", autonomous being "governing itself" (or "self-sufficient"), etc.
