RUSSIAN scientist, Denis Logunov, a lead developer of the Sputnik V coronavirus vaccine, said on Friday that the shot had proven itself 97.6 per cent effective against COVID-19 in a real-world assessment, based on data from 3.8 million people.
The new effectiveness rate is higher than the 91.6 per cent rate outlined in results from a large-scale trial of Sputnik V and published in The Lancet Medical Journal earlier this year.
Using a database of people who received both doses of the vaccine, scientists at Moscow’s Gamaleya Institute, which developed it, calculated a real-world effectiveness rate of 97.6 per cent, Logunov said during a presentation for the Russian Academy of Sciences. (Reuters)
