Russia’s Sputnik V Coronavirus Vaccine 92% Effective – Interim Data

 

 Russia’s Sputnik V coronavirus vaccine is 92% effective, its developers said Wednesday as the global race heats up over mass vaccination to slow the spread of the pandemic that has killed nearly 1.3 million people and battered economies worldwide.
Interim results showed that 20 of the 16,000 volunteers who received both Sputnik V doses have contracted Covid-19, the Russian Health Ministry, state-run Gamaleya research center and Russian Direct Investment Fund (RDIF) said in a statement.

“As a result of a statistical analysis of 20 confirmed cases of coronavirus, the case split between vaccinated individuals and those who received the placebo indicates that the Sputnik V vaccine had an efficacy rate of 92% after the second dose,” the statement said.
More than 20,000 volunteers have received the first dose of Sputnik V as of Wednesday, according to Gamaleya, the Health Ministry and RDIF.
The developers said that “some” of the volunteers experienced short-term “pain at the injection site [and] flu-like syndrome including fever, weakness, fatigue and headache.” They noted that these adverse effects were expected.
