Earlier, the study was conducted using sera with a long period after vaccination (more than 6 months after vaccination) as an indicator of Sputnik V's long-lasting protection, Sputnik V's statement mentioned.

Further, the preliminary study by the Gamaleya Centre has demonstrated that the Sputnik V vaccine and the one-shot Sputnik Light booster (based on human adenovirus serotype 26, the first component of Sputnik V) are effective against Omicron (B.1.1.529) variant of COVID, providing for better protection when compared to other vaccines. Also, Heterologous boosting with Sputnik Light is the solution to increase other vaccines' efficacy, including against Omicron, and extend the booster protection period. Also, Sputnik Light as a booster significantly increases virus neutralising activity against Omicron based on sera 2-3 months after revaccination and is a universal booster to other vaccines inducing stronger antibody and T-cell response, according to Sputnik V's press release.
