This existing immune system "memory" may explain why some people have milder COVID-19 infections.
"We have now proven that, in some people, preexisting T-cell memory against common cold coronaviruses can cross-recognize SARS-CoV-2
It's possible that this "immune reactivity may translate to different degrees of protection" against COVID-19, study co-lead author Alessandro Sette, a professor at La Jolla Institute for Immunology, said in the statement. "Having a strong T-cell response, or a better T-cell response may give you the opportunity to mount a much quicker and stronger response."
