Furthermore, Dr. Freidrich says while human corona virus infections are quite common and most of us likely have some immunity to human corona viruses that cause the common cold, this does not appear to protect people against COVID-19. Although scientists are examining the role of receptors, Spaan stresses that they are looking at the impact of genes on the entire cycle of SARS-CoV-2 infection and disease development.

In that case, Bogoch says a person can still transmit the virus to others but has developed antibodies, or an "immune fingerprint," showing that something was there. As explained in their lab study, they used CRISPR genome editing technology to disable the 20,000 genes in human lung cells, then exposed the cells to SARS-CoV-2 and watched what happened. These include their overall health, how much of the virus was shed by COVID-stricken people around them, and the strength of their immune systems. Sanjana points out that genes exist to serve critical functions, and disabling any of those functions creates risks for unintended harmful consequences. In other words, it may be interesting scientifically, but perhaps not clinically. To their surprise, they found antibodies that reacted to SARS-CoV-2 in some of the samples.
