MOSCOW (Sputnik) – The single-shot Sputnik V Light version of the Russian vaccine against coronavirus decreases the chance of infection by 50-60 percent, Alexander Gintsburg, director of the Gamaleya research institute behind the vaccine, said on Sunday.
The slimmed-down version of the vaccine was registered in late March as an alternative to the main two-shot Sputnik V after successfully undergoing all three phases of clinical trials. The latter will remain the main version.
According to a publication in the Lancet medical journal, the two-shot Sputnik V is 92 percent effective at preventing symptomatic illness and 100 percent in preventing severe disease.
