MOSCOW, March 19. /TASS/. Russia’s Convacell coronavirus vaccine will be effective against the stealth Omicron variant, Head of the Federal Medical Biological Agency (FMBA) Veronika Skvortsova told the Rossiya-24 TV channel on Saturday.

"Indeed, we recorded the development of combined immunity with very high protective properties and complete seroconversion. The share of cases where high titers of immunoglobulin G tagerting N protein were detected is 100%, besides, specific cells and cellular immunity are also developed and central memory cells emerge, which guarantees that the protective effect of the vaccine will remain in place for a long time," she explained.

On Friday, Russia’s Health Ministry registered the Convacell coronavirus vaccine developed by the FMBA’s St.Petersburg Research Institute of Vaccines and Serums.
