they have all had the Rona, though not all of them had the antibodies. We knew one had it when she lost her taste and smell so we said lets go ahead and all get it. We did not get tested for the virus, only got the antibody test after the fact and though we all had the same symptoms, though to varying degrees, and we shared drinks, food etc and only 4 of 6 had the antibodies after the episode - the two that did not were my wife and my 12 year old which is really weird. So I think we are all pretty safe.
