MOSCOW, February 12. /TASS/. The effective term of the Sputnik Light vaccine will be three-four times shorter than that of the Sputnik V preparation consisting of two components, Alexander Gintsburg, director of the Gamaleya National Research Center for Epidemiology and Microbiology that developed Sputnik V, said on Friday.

"The duration of protective action of Sputnik Light will be at least 3-4 times less than the duration of action of a vaccine consisting of two components," he said in an interview with the Russia-24 TV channel.

According to the developer, most likely Sputnik Light will protect against the coronavirus for 4-5 months.

On August 11, 2020, Sputnik V became the first registered vaccine against the coronavirus worldwide. On December 17, Russian President Vladimir Putin mentioned the possibility of creating a light version of the preparation.
