The study, conducted based on the blood serum of 9 people vaccinated with Sputnik V, as well as 6 revaccinated with Sputnik Light, concluded that the neutralizing activity against omicron is greater 2 to 3 months after the booster with Sputnik Light than the activity against the virus original 6 months after vaccination with Sputnik V.

Based on these data, it is expected that the efficiency of Sputnik V together with the reinforcement of Sputnik Light, could be higher than 80% against this variant, since Sputnik V showed greater than 80% efficacy against wild-type virus 6 months after vaccination.

Furthermore, the scientists explain that Sputnik Light is a universal booster for other vaccines it can boost the antibody response, even against omicron, and extend the protection period of the boost.

In trials in Argentina of combination with vaccines produced by AstraZeneca, Sinopharm, Moderna and Cansino it was shown that Sputnik Light “induces a greater response of antibodies and T cells compared to the homogeneous regimen [dos inyecciones de la misma vacuna]Each combination showed a higher antibody number on day 14 after administering this component as a second dose compared to the original homogeneous regimens of each of the vaccines.
