The Battle to Find Vaccine Continues as Russia Claims its Coronavirus Vaccine is 92% Effective

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.”
