COVID-19 Survivors Have Immune Protection Against Reinfection

A Harvard Univerity - Massachusetts General Hospital led study reported on October 8, 2020, that people who survive serious COVID-19 infections have long-lasting immune responses against the new coronavirus.

“We can say now that if a patient has IgA and IgM antibody responses, they were likely infected with the virus within the last 2-months,” stated Richelle Charles, a professor of medicine at Harvard Medical School, and co-lead of this new study.

The study was published in Science Immunology, offers hope that people infected with the coronavirus will develop lasting protection against reinfection.
