Two studies on monkeys published on Wednesday offer hope that humans can develop protective immunity to the novel coronavirus.
The studies, published in the journal Science, looked at a prototype vaccine and whether infection with SARS-CoV-2 provides immunity against re-exposure.
“The global COVID-19 pandemic has made the development of a vaccine a top biomedical priority, but very little is currently known about protective immunity to the SARS-CoV-2 virus,” said senior author Dan Barouch, director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center in Boston.
The monkeys developed COVID-19 symptoms but created protective antibodies and recovered after a few days. “Rigorous clinical studies will be required to determine whether SARS-CoV-2 infection effectively protects against SARS-CoV-2 re-exposure in humans,” they said.
