Researchers found antibodies against the SARS-CoV-2 spike protein receptor-binding domain (RBD) in 99 percent of study participants who tested positive for COVID-19, with some having had the illness as long as 20 months prior.
"The major takeaway is that natural immunity … is strong and durable," [Dr Dorry] Segev told The Epoch Times in an email.
Dr. Dorry Segev, the director of the Epidemiology Research Group in Organ Transplantation at Johns Hopkins University.
