An international team of researchers is in the process of recruiting potential study participants who fit the so-called “never COVID” cohort. They are looking for people who were exposed to someone with COVID-19 for a lengthy period, without protection, and never got sick or tested positive for the virus. For example, in some cases an entire family...
Another study, published in Nature Communications, shows that some individuals have what might be a pre-existing immunity to COVID-19. “The hypothesis is that people with increased exposure to other versions of coronaviruses will have ‘premade’ T cells that cross-react with COVID-19 and are able to quickly respond to COVID-19 infection,” Sensenig e...
In addition to potential immune system or genetic factors, other people may have never developed COVID-19 if they evade exposure. For example, some people have had the ability to work from home or practice rigorous social distancing. Masking and following vaccination and booster recommendations from public health experts prevented many infections, ...
