Researchers investigating what may determine whether a novel coronavirus vaccine candidate proves successful say they have found evidence that suggests previous exposure to a coronavirus, like one that causes the common cold, could possibly provide some form of protective immunity against COVID-19.
The team, at La Jolla Institute of Immunology, studied a group of 20 adults who had successfully recovered from COVID-19 and found that the body’s immune system is able to recognize SARS-CoV-2 “in many ways,” according to their research, which was published in the journal Cell.
“Given the severity of the ongoing COVID-19 pandemic, any degree of cross-reactive coronavirus immunity could have a very substantial impact on the overall course of the pandemic and is a key detail to consider for epidemiologists as they try to scope out how severely COVID-19 will affect communities in the coming months,” Dr. Shane Crotty, another study author, said in the news release.
