The World Health Organization estimated on Thursday that millions of coronavirus vaccine could be produced in the end of 2020.
The United Nations health agency said it was working on the vaccine and hoped that two billion doses of them can be made by the end of this year when pharmaceutical companies are developing a vaccine.
WHO chief scientist, Soumya Swaminathan said researchers were working with over 200 vaccine candidates in the world and ten of them are testing on humans now. One or two candidates would give out good results by the end of 2020 if we are lucky, she added.
Swaminathan suggested that those who are vulnerable should inject the validate vaccine first. Front-line workers like medics and police officers, elderly people, patients with diabetes and people in high-transmission settings, like urban slums and care homes are those who are in need of the vaccine.
