The Russian Direct Investment Fund (RDIF, Russia’s sovereign wealth fund), and Mumbai-based Wockhardt have partnered to produce and supply Sputnik V and Sputnik Light vaccines against COVID-19. The agreement was reached under the aegis of Enso Healthcare (part of Enso Group), RDIF's coordination partner for sourcing Sputnik V vaccines in India.

Sputnik V is based on a proven and well-studied platform of human adenoviral vectors and uses two different vectors for the two shots in a course of vaccination, providing immunity with a longer duration than vaccines using the same delivery mechanism for both shots. While Sputnik Light is the first component of Sputnik V and is based on human adenovirus serotype 26.

Sputnik V demonstrates 83.1% efficacy against the Delta variant of coronavirus - higher than many other vaccines. The vaccine shows 6 times reduction of infection risk. Sputnik V is also 94.4% effective against hospitalisations with 18 times reduction in hospitalisation risk.
