WHO hopeful COVID-19 vaccines could be available before end of 2020
World Health Organisation’s chief scientist, Dr Soumya Swaminathan has said that the agency is optimistic and hopeful that the COVID-19 vaccines could be available before the end of this year. She said, there are about 10 candidates which are in human testing phase and at least three of them are entering the new promising phase-three stage which proves a vaccine’s efficacy.
If we are lucky, there will be one or two successful candidates before the end of this year, she added. The chief scientist said that the agency hopes there will be about two billion doses of a vaccine against COVID-19 by the end of next year that would be reserved for priority populations.
