Data suggests Russia's one-shot Sputnik Light COVID-19 vaccine 70% effective against Delta virus variant
13 October 2021 -

The Russian Direct Investment Fund (RDIF), Russia's sovereign wealth fund, has said that the country's one-shot Sputnik Light COVID-19 vaccine shows 70% effectiveness against the Delta variant of COVID-19 three months after injection, Reuters news agency reported on Wednesday.

According to the RDIF, this data was submitted by the vaccine developer, the Gamaleya Institute, to medical website medRxiv ahead of a peer review.

It was based on 28,000 participants who received a dose of Sputnik Light, as compared with a control group of 5.6 million individuals who were not vaccinated.

The RDIF, which markets Sputnik V internationally, stated that Sputnik Light as a booster for other vaccines will be almost as effective against the Delta variant as Russia's flagship two-shot Sputnik V vaccine.

RDIF added that Sputnik Light would be over 83% effective against infection and over 94% effective against hospitalisation.

Kirill Dmitriev, head of the RDIF, told Reuters: "Eventually, we believe that Sputnik Light could be the main vaccine one year from now when many people will just need to get revaccinated or will have had COVID and won't need Sputnik V."
