Sputnik is 90 percent more effective against the delta variant, the Russians say.
All this is stated by Alexander Semyonov, head of the Russian Consumer Protection Research Institute of Viral Infection in Yekaterinburg.
“The effectiveness of vaccines is declining slightly, but according to the latest data, it still remains above the 90 percent level. Surveillance is ongoing and virus neutralization tests are performed on all new virus isolates. “
Semionov said of the Russian vaccine. For all these reasons, he does not consider it necessary to change the composition of the vaccines.
