Great news! Study says immunity to COVID-19 can last years

Wednesday, November 18, 2020 • Tamil Comments

New York Times has reported that immunity to the coronavirus might last years or decades, as per a new, credible study. For months now, many have feared that the immunity may last only a few months, in which case COVID-19 might not have a solution at all. As per the study, as much as 90% of those infected once will not face a recurring infection.

Health journalist Apoorva Mandavilli of NYT has tweeted that nations probably will not need to vaccinate people every year if reinfections are very rare. Drawing a parallel with the survivors of SARS, she writes that human bodies have similar levels of immunity to COVID-19 as well.

"The vast majority of people in the new study have robust levels of B cells (which can make antibodies as needed), as well as the types of T cells needed to fight the virus, and they show extremely slow rates of decline — consistent with many years of protection," the reporter tweets out.


This news comes in the wake of Pfizer and Moderna developing "safe, effective" vaccines. Moderna's vaccine will be suitable for Indian conditions.
