Russia says its coronavirus vaccine is 92% effective, as battle to beat Western drugmakers heats up

Russia said Wednesday its coronavirus vaccine is 92% effective at preventing people from getting Covid-19, based on interim trial results.

The announcement by Russia’s sovereign wealth fund RDIF came two days after U.S. pharmaceutical giant Pfizer and its German partner BioNTech said their vaccine was more than 90% effective in phase three trials.

RDIF said the early results from its late-stage phase three clinical trial of the vaccine, called “Sputnik V,” showed that its efficacy was “based on the 20 confirmed Covid-19 cases split between vaccinated individuals and those who received the placebo.”

“Currently 40,000 volunteers are taking part in double-blind, randomized, placebo-controlled Phase III of Sputnik V clinical trials, out of which over 20,000 have been vaccinated with the first dose of the vaccine and more than 16,000 with both the first and second doses of the vaccine,” a statement published on the dedicated Sputnik V website said Wednesday.
