(CNN) — The WHO warns that it is not until 2022 when the world can begin to think about returning to life “before COVID”.
So said the doctor on Tuesday Soumya Swaminathan, Scientific Director of the World Health Organization (WHO) in Geneva.
“We are looking at at least 2022 before enough people start getting the vaccine to build immunity. Therefore, for a longer time, we will have to maintain the same type of measures that are currently being implemented with the physical distancing, the use of a mask and respiratory hygieneSwaminathan said, speaking to journalists during a virtual meeting organized by the United Nations Foundation.
“This will need to continue after the vaccine starts., because we need 60% to 70% of the population to have immunity before we start to see a dramatic reduction in the transmission of this virus, ”said Swaminathan.
“We also don’t know how long these vaccines will protect; that’s the other big question mark: How long does immunity last? And a booster may be needed“.
Swaminathan added that health officials are currently seeking control the coronavirus that causes COVID-19, rather than eliminating it at this time.
While the timeline remains uncertain and difficult to predict, “I think it’s safe to say that it could be 2022 when we will begin to think about returning to a normal life before COVID “Swaminathan said.
Swaminathan added that you don’t think coronavirus will become a seasonal virus as time goes byRather, we might expect to see “ups and downs” in cases and transmission.
