Moscow: Russian Sputnik V Vaccine against Covid-19 is 83% effective against the Delta variant of the Coronavirus novel, lower than the previous thought, Minister of Health Mikhail Murashko said on Wednesday.
The vaccine developer said in June that Sputnik v was around 90% effective against the Delta variant.
Claims have come at a time in June and July, when the authorities have blamed the wave in the case of the Coronavirus on a more contique Delta variant and the reluctance of residents to vaccinate widely regardless.
But the latest results indicate that effectiveness is around 83%, Tass news agency quotes Murashko.
Alexander Gintsburg, Director of the Gamaleya Institute, who developed a vaccine, said on Wednesday in an interview with the Izvestia newspaper that Sputnik V was safe and effective against all the Coronavirus strains.
Russia, which has a population of around 144 million, has approved four vaccines produced domestically.
It has recorded nearly 6.5 million infections since the commencement of Pandemi.
