Russia has registered Sputnik Light, the single-dose vaccine against COVID-19, which has an efficacy of 79.4 percent, the Russian Direct Investment Fund (RDIF) said.

“The Russian Ministry of Health, the Gamaleya National Research Center of Epidemiology and Microbiology and the Russian Direct Investment Fund announce that Sputnik Light, a single dose COVID-19 vaccine, has received authorization for use in Russia … The single-dose Sputnik Light vaccine demonstrated 79.4% efficacy according to analyzed data taken from 28 days after the injection was administered. An efficacy level of near 80% is higher than that of many two-dose vaccines,” the press release read.

According to the statement, the efficacy of Sputnik Light was calculated based on data obtained from Russians “vaccinated with a single injection, having not received the second one for any reason during the mass vaccination program between December 5, 2020 and April 15, 2021.”
