Seasonal colds are by all accounts no fun, but new research suggests the colds you’ve had in the past may provide some protection from COVID-19. The study, authored by infectious disease experts at the University of Rochester Medical Center, also suggests that immunity to COVID-19 is likely to last a long time — maybe even a lifetime.
The study, published in mBio, is the first to show that the COVID-19-causing virus, SARS-CoV-2, induces memory B cells, long-lived immune cells that detect pathogens, create antibodies to destroy them and remember them for the future. The next time that pathogen tries to enter the body, those memory B cells can hop into action even faster to clear the infection before it starts.
Because memory B cells can survive for decades, they could protect COVID-19 survivors from subsequent infections for a long time, but further research will have to bear that out.
