Sputnik V vaccine effective against Omicron - Putin

Sputnik V is one of Russia's four domestically approved COVID-19 vaccines.

Also on Friday (December 17) a study which has not yet been peer reviewed said that COVID-19 vaccines from U.S. drugmaker Johnson & Johnson, China's Sinopharm and Russia's Sputnik V shot had no neutralizing activity against the Omicron variant.

It was conducted by Humabs Biomed SA, a unit of Vir Biotechnology, and the University of Washington, among others.

Russia's Gamaleya Center issued a statement saying that the Sputnik V shot was tested "deliberately using serum samples that are not representative" and thus, conclusions about its effectiveness against the Omicron variant based on the study could not be made.
