RUSSIA'S CORONAVIRUS VACCINE IS 91.6% EFFECTIVE
Russia's coronavirus vaccine is 91.6% effective, said an interim analysis of phase-3 data published in The Lancet.
Russia approved the drug for emergency use in August, before phase 3 trials, and started giving it to the public in December.
One expert said the study had some caveats, but that the results seem to endorse Russia's strategy.
Russia's Sputnik V coronavirus vaccine is 91.6% effective, an interim analysis of its phase 3 data has found, five months after the country approved the vaccine for use and started giving it to people.
The peer-reviewed study was published in The Lancet on Tuesday. Many of the study's authors are affiliated with Russia's ministry of health, according to The Lancet.
Dr. Julian Tang, a consultant virologist at the UK's University of Leicester, said the interim analysis showed the vaccine to be 91.6% effective after two doses.
But he noted that the trial was only conducted on participants who self-reported symptoms and were then tested, meaning the results only include people with COVID-19 symptoms.
