New studies claim COVID-19 immunity may last years

Most people who recover from COVID-19 could have immunity that lasts at least a year or even longer — and may not need a booster shot after being vaccinated, as pair of new studies suggest.

The first study, published Monday in the journal Nature, found most people who were infected with the virus about a year earlier had immunological memory of the disease in their bone marrow, suggesting they’re still able to produce antibodies. And another report, which was published on the pre-print server BioRxic, found that these cells — called “memory B” — were robust for at least 12 months after infection.
