Sputnik Light Has 80% Efficacy, Effective against All New Covid Strains
Moscow: The Russian Government today announced that Sputnik Light, a single dose COVID-19 vaccine, has received authorization for use in the country.
Sputnik Light is the first component (recombinant human adenovirus serotype number 26 (rAd26)) of the Sputnik V coronavirus vaccine.
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 efficacy rate 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, according to an official statement.
The infection rate among vaccinated subjects from the 28th day from the date of the injection was only 0.277%. Over the same period, the infection rate among the unvaccinated adult population was 1.349%.
