Had a neighbor and good friend participate in a study today where they did the antibody tests for Covid-19. Both were positive for the antibody but have had no symptoms other than being sick in January. The tests showed they would have had it more than 21 days ago. I sent a message to my primary care physician to see when/if they’d have them anytime soon and he still didn’t know. It’s his belief, as it is mine that millions of people have already had Covid-19 and are now immune.
