Antibodies may feel like an extra shield of protection for recovered COVID-19 patients, but experts warn against relying on them to stop the spread.
There is “credible evidence” of reinfection and it’s “probably more common” than we think, says infectious disease expert Dr. Isaac Bogoch.
Immunity is “a dance between the virus and the person’s immune system,” he told CTVNews.ca over the phone on Tuesday. “That’s going to be different for every single person. It’s not quite clear who’s going to have what degree of immunity for what period of time.”
Though a growing body of research shows that SARS-CoV-2 antibodies can be present for many months after infection, their presence does not equal immunity to reinfection, scientists stress. There remains a lack of evidence as to how much immunity coronavirus antibodies provide, if any at all, though U.S. President Donald Trump recently made news for claiming otherwise.
