Dr. Yonatan Grad, an assistant professor of immunology and infectious diseases at the Harvard T.H. Chan School of Public Health, wrote recently in an op-ed for STAT that there are two ways to achieve this: immunity from infection or immunity through vaccination. “We hope that when you get infected with the virus, you develop sufficient immune protection to prevent subsequent infection, at least for a little while,” he told CBC News. Antibodies arise after someone has recovered from COVID-19, but the timing can vary between individuals. The World Health Organization says the average recovery time for mild cases is about two weeks and three to six weeks for patients with severe disease. Patients can still infect others for up to two weeks after symptoms disappear.
