Scientists See Signs of Lasting Immunity to COVID-19, Even After Mild Infections

To the immune system, not all germs are equally memorable. But our body’s cells seem to be seriously studying up on the coronavirus.

Scientists who have been monitoring immune responses to the virus are now starting to see encouraging signs of strong, lasting immunity, even in people who developed only mild symptoms of COVID-19, a flurry of new studies suggests. Disease-fighting antibodies, as well as immune cells called B cells and T cells that are capable of recognizing the virus, appear to persist months after infections have resolved — an encouraging echo of the body’s enduring response to other viruses.

“Things are really working as they’re supposed to,” said Deepta Bhattacharya, an immunologist at the University of Arizona and an author on one of the new studies, which has not yet been peer-reviewed.

Although researchers cannot forecast how long these immune responses will last, many experts consider the data a welcome indication that the body’s most studious cells are doing their job — and will have a good chance of fending off the coronavirus, faster and more fervently than before, if exposed to it again.


Governor Cuomo Announces 7 Million COVID-19 Tests Conducted to Date in New York State

Governor Andrew M. Cuomo today announced 7 million diagnostic tests for COVID-19 have been conducted to date in New York State, and that the number of positive cases yesterday — 0.78 percent — was below 1 percent for the ninth day in a row.

“Our numbers reflect the hard work of New Yorkers, and as other states across the nation see surging cases, our numbers remain steadily low. For more than a week, we’ve seen our positivity rate stay below 1 percent, and to date New York has done 7 million tests—these are remarkable accomplishments that New Yorkers should be proud of,” Governor Cuomo said. “New York State is demonstrating that a response guided by science and data – not politics or opinion – is the only effective way to deal with this virus. But, we must not become complacent and risk slipping backwards — everyone must remember to wear their masks, socially distance, wash their hands regularly, and stay New York Tough.”
