        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.

            Where did you live? I always wore a mask around other people, but I also live in a rural area, so I didn’t need to wear a mask for that many hours comparatively.

              Also in a more rural area. After Covid was over I got pretty sick 4-5 times from just normal colds. What used to be a slight headache had me bedridden. This happened a few times but gradually improved.

              Now years later my immune system is back up and running again.
