If efficacious vaccines are produced for our public, I think it is a good bet that many people will take it and many people will refuse leaving a mixed bag of people theoretically immune to COVID-19 for some unknown period of time. Add to that people who have had the disease and recovered theoretically building antibodies also making them immune and incapable of transmitting the disease as well.

Question: will those people thus unable of transmitting the disease be exempt from the mandatory edicts of wearing the face diapers/distancing and how would we verifiably know who qualifies? Or, like now for people who have recovered, would everyone still have to wear the damned things?
