Strong antibody responses against harmless coronaviruses also partially protect against SARS-CoV-2.
Infections with the novel coronavirus and vaccination lead to strong antibody responses against SARS-CoV-2. Immune responses to other human coronaviruses, which mostly only cause harmless colds, also provide some protection against SARS-CoV-2. This cross-reactive immune response is an important piece of the puzzle of how to achieve comprehensive coronavirus immunity, researchers at the University of Zurich have shown.
The population’s immunity to SARS-CoV-2, achieved either through infection or vaccination, is crucial to overcome the COVID-19 pandemic.
A team of researchers led by the University of Zurich (UZH) has now discovered another component that contributes to SARS-CoV-2 immunity – previous antibody responses to other, harmless coronaviruses.
“People who have had strong immune responses to other human coronaviruses also have some protection against SARS-CoV-2 infection,” says Alexandra Trkola, head of the Institute of Medical Virology at UZH. ...snip...
