Coronavirus vaccine and Delta mutation: From 90% to 83% the effectiveness of Sputnik V

The Russian Sputnik V coronavirus vaccine is about 83% effective against the coronavirus delta mutation, less than previously thought.

The Russian authorities attribute the increase in coronavirus cases in June and July to the most contagious Delta mutation and the reluctance of the population to be vaccinated, despite the fact that vaccines are widely available in the country.

The latest results show that the efficiency is about 83% “, said the Minister of Health of Russia, Mikhail Murasko, according to press sources.

Alexander Ginzburg, director of the Gamaleya Institute that developed the vaccine, said today that Sputnik V is safe and effective against all coronavirus strains.
