WHO Chief Scientist Soumya Swaminathan has said "a healthy young person might have to wait for coronavirus vaccine until 2022." "Most people agree, it's starting with health care workers, and front-line workers...and then the elderly, and so on," Swaminathan added. "You need to vaccinate at least 70% of people to really break transmission," she further stated.
