Follow RT on Following a large scale trial, Russia s pioneering Sputnik V vaccine has proven to be 91.4 percent effective overall against Covid-19, its creator said on Monday, as the country embarks on a national mass vaccination program.
In a statement, Moscow s Gamaleya Institute and Russian Direct Investment Fund (RDIF), which funded the vaccine’s development, cited data received from volunteers 21 days after they were inoculated with the first dose of the jab. The results confirmed a 91.4 percent efficacy rate overall and showed that it is
“100 percent” effective against severe cases of the virus.
In practice this means that while some of the formula s recipients may still become infected, their cases will be mild.
