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.

Masking and following vaccination and booster recommendations from public health experts prevented many infections, ...
