Russian V Sputnik Effectiveness Against Omicron 75 Percent: Vaccine Developers

Moscow: The effectiveness of Sputnik V Covid-19 vaccine against Omicron Coronavirus variants is 75 percent, Alexander Gintsburg, the Head of the Russian Gamaleya Research Center, said on Tuesday.
“In the population, the effectiveness of v sputnik vaccines in connection with Omicron …
is 75 percent,” Gintsburg said at the press center Rossiya Segode.
Gamaleya’s head added that the protection of Omicron increased to 100 percent if someone received a sputnik light booster dose in six months but decreased to 56-57 percent if the circuit was not carried out.
The effectiveness of Sputnik V to Omicron decreases eight times but is still sufficient for protection, Gintsburg said, adding that the effectiveness of other vaccines decreases 21 times.
