coronavirus vaccine has more than 95% efficacy according to new preliminary data, giving it a success rate comparable to vaccines being developed by Pfizer and Moderna.
Russian officials also claimed their vaccine had greater efficacy than the Oxford/AstraZeneca vaccine because of Russia’s proprietary technology, which it offered to share with British scientists.
“Sputnik shows very high effectiveness, higher than 95%,” Kirill Dmitriev, the head of the Russian Direct Investment Fund, said during a briefing on Tuesday. “This is indisputably positive news not just for Russia, but for the entire world, for all countries.”
The Sputnik results were computed after 42 days of a study in which 19,000 participants received two doses of the vaccine and 21,000 participants received a single dose. Earlier data showed that the vaccine had an approximately 91.4% efficacy 28 days after participants received the first dose.
