Russia says COVID-19 vaccine is 92% effective on early data
November 12, 2020
MOSCOW - Developers of Sputnik V, Russia's experimental COVID-19 vaccine, announced Wednesday that early, interim data from a large trial suggests the shot appears to be 92% effective.
The statement, which did not include detailed information about the trial, comes just two days after a similar one from Pfizer Inc., but is based on far fewer virus cases. Some experts suggest the data may have been rushed out in an effort to keep up with the worldwide race for a successful coronavirus vaccine.
Russia touted Sputnik V, a two-shot vaccine, as the world's first to receive a government go-ahead after it was approved in early August without completing advanced testing. The move drew considerable criticism from experts who said data from tens of thousands of people were needed to ensure the safety and effectiveness of the vaccine before it is given widely.
