"Most people agree, it's starting with healthcare workers, and frontline workers, but even there, you need to define which of them are at highest risk, and then the elderly, and so on," Swaminathan was quoted as saying to The Guardian.
"There will be a lot of guidance coming out, but I think an average person, a healthy young person might have to wait until 2022 to get a vaccine," she added.
Swaminathan also warned against complacency about the virus death rate, saying with the increasing number of cases, mortality would also rise.
"Mortality increases always lag behind increasing cases by a couple of weeks. We shouldn't be complacent that death rates are coming down," WHO's chief scientist said.
