The WHO says a COVID-19 vaccine could be developed by the end of the year

On June 18 local time, WHO chief scientist Sumiya Swaminathan said that at least 200 COVID-19 vaccines are under development and about 10 have entered human trials. Three of them will soon enter phase III clinical trials, including one from China.

Sumiya Swaminathan notes that China has several vaccine candidates, and the results of phase I and II clinical trials show promise.

Sumiya Swaminathan also says one or two successful vaccine candidates could be available by the end of the year. The goal is to have 2 billion doses of vaccine produced by 2021. Fortunately, novel Coronavirus appears to have far fewer mutations than influenza viruses, and the mutations that lead to such critical parts as disease severity and immune response have not yet been shown.
