“We have more than 200 candidate vaccines, and six of them are at a very good stage, undergoing clinical trials,” TASS quotes him as saying.

The head of WHO spoke in favor of the availability of a future vaccine against coronavirus infection for the world's population, stressing that such a vaccine should be considered a "public good."

Previously, director of the National Research Center for Epidemiology and Microbiology named after N.F. Gamaleya of the Ministry of Health of Russia, Alexander Gintsburg, said that the decrease in herd immunity in the autumn-winter period in citizens is one of the important criteria for the need for a vaccine against coronavirus infection.
