Immunity to coronavirus lingers for months, study finds

Immunity to Covid-19 infection lingers for at least five months, researchers reported -- and probably longer than that.

While the report may seem confusing and contradictory to a similar report out of Britain this week, it really isn't. People's bodies produce an army of immune compounds in response to an infection and some are overwhelming at first, dying off quickly, while others build more slowly.

The new report out Wednesday shows 90% of people who recover from Covid-19 infections keep a stable antibody response."While some reports have come out saying antibodies to this virus go away quickly, we have found just the opposite -- that more than 90% of people who were mildly or moderately ill produce an antibody response strong enough to neutralize the virus, and the response is maintained for many months," Florian Krammer, a professor of vaccinology at the Icahn School of Medicine at Mount Sinai, who led the study team, said in a statement.

"This is essential for effective vaccine development."
