What does a low dose immunity take? Does it prevent a possible 1918 reoccurrence? Is it like varicella zoster virus, get it young to prevent a serious later exposure that could be deadly to an older person. Are non-high risk” young humans being inappropriately masked?
Big coronavirus unknowns: 1. Will it subside over summer? 2. What fraction of the population has been exposed and did not develop symptoms? 3. If you were infected and recovered, do you have immunity or can you get infected again? 4. If you have immunity, how long does that last?
