New Delhi: Omicron is spreading like forest fire globally with infections now reported on six continents. Amid this Russia has stated that the Sputnik-V vaccine is effective against the Omicron variant of COVID. Developed by Gamaleya Research Institute, part of Russia's Ministry of Health, Sputnik V demonstrated high virus-neutralizing activity (VNA) against the Omicron.
According to the data released by the government, the vaccine performed three to seven times better than other candidates, including those developed using mRNA technology. The Sputnik Light, meanwhile, showed an efficacy of 80 percent.
"Sputnik V induces robust neutralizing antibody response to #Ois micron, further strengthened by Sputnik Light booster, performing 3-7X better than other (including mRNA vaccines). Light's efficacy vs Omicron expected to be more than 80 percent after 2-3 months," RDIF shared on Twitter.
As per the study, RDIF said, virus-neutralizing activity (VNA) against Omicron, within two three months of a Light booster, was found to be higher than VNA against 'wild-type' virus six months after injection of the two Sputnik V doses. "Based on these data, the expected efficacy of Sputnik V with Sputnik Light booster against Omicron could be more than 80 percent," it said.
"100 percent of people revaccinated with Light as booster developed neutralizing antibodies against Omicron two-three months after revaccination, in contrast with 25 percent for the Pfizer booster three months after revaccination," Russia's sovereign wealth fund further noted.
