Exposure to one virus rarely leads to a resistance to another one. That’s why they have a new flu vaccine every year even though they’re all closely related. Cow pox immunizating against small pox was a fluke
It’s more about being exposed to everyday bacteria, pollen, and hot/cold cycling that gives your immune system exercise.
