MOSCOW (BLOOMBERG, REUTERS) - An analysis of the 3.8 million Russians who received both Sputnik V shots between December and March showed that the vaccine has 97.6 per cent efficacy, the inoculation's state-run developers said in a statement on Monday (April 19).
The data, which compare the infection rate of people who received the shots with the incidence among the unvaccinated population, will be published in a peer-reviewed journal in May, according to the Russian Direct Investment Fund and Gamaleya National Research Centre.
The new effectiveness rate is higher than the 91.6 per cent rate outlined in results from a large-scale trial of Sputnik V and published in The Lancet medical journal earlier this year.
