Immunity to the coronavirus lasts at least a year, probably much longer.

Two  new studies suggest that most people who have recovered from Covid-19 and who were later immunized will not need boosters. 

Vaccinated people who were never infected most likely will need the shots, however, as will a minority who were infected but did not produce a robust immune response.

Both reports looked at people who had been exposed to the coronavirus about a year earlier. Cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed, according to one of the studies, published Monday in the journal Nature.

The other study, found that these so-called memory B cells continue to mature and strengthen for at least 12 months after the initial infection.

“The papers are consistent with the growing body of literatures.

We need a new look at the natural immunity for the young. Just a thought.
