Russia-s Sputnik V vaccine has been found to be more than 95 per cent effective against Covid-19 in the second interim analysis of Phase 3 clinical trial data, its developers said on Tuesday.
The analysis was based on data from volunteers obtained 42 days after the first dose -- which corresponds with 21 days after the second dose, Gamaleya National Research Centre for Epidemiology and Microbiology of the Russian Health Ministry and Russian Direct Investment Fund RDIF, said.
