Monkeys develop virus immunity after infection, vaccine

WASHINGTON: 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. Both questions are critical as researchers tackle the virus, which has infected nearly five million people around the world and caused more than 325,000 deaths. The studies were carried out on rhesus macaque monkeys to see whether they develop protective virus immunity from natural infection or from a vaccine. “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.
