This is reported by TASS with reference to Inna Dolzhikova, head of the laboratory of the state collection of viruses of the Gamaleya National Research Center for Epidemiology and Microbiology, one of the developers of Sputnik V.

According to her, the effectiveness of the drug with the initial antigenic composition for the entire period of the pandemic was assessed.

"Despite the fact that the level of protection of the vaccine against infection has changed due to the emergence of new variants of the virus, Sputnik V provides reliable protection against deaths at the level of 90% and protection against hospitalizations at the level of more than 80%," Dolzhikova said.

According to her, in this way, the drug still protects the vaccinated.

Earlier, the chief freelance specialist of the Russian Ministry of Health on infectious diseases, Professor Vladimir Chulanov, said in an interview with RT that the Sputnik vaccine with a new antigenic composition had passed preclinical trials.
