LOS ANGELES - Immunity created after being infected with COVID-19, in addition to getting vaccinated, could last in the body for years, according to two new studies published this month.
In both studies, one published in the journal "Nature" and the other published online at BioRxiv, authors noted that memory B cells were largely responsible for creating a longer immune response and subsequent immune memory to prevent future infection from COVID-19 and other variants for longer than 6-12 months. "The data suggest that immunity in convalescent individuals will be very long-lasting and that convalescent individuals who receive available mRNA vaccines will produce antibodies and memory B cells that should be protective against circulating.
