Sputnik V Demonstrates 97% Efficacy Against Hospitalisation Caused By Omicron Variant: Study

New Delhi, June 15 (TNA) The Gamaleya National Research Center of Epidemiology and Microbiology (Gamaleya Center) on Wednesday announced that Vaccines, the leading peer-reviewed medical journal, has published the results of a joint study conducted by team of scientists including representatives of Moscow’s City Clinical Hospital No. 67 named after L.A. Vorokhobov and the Gamaleya Center showing the two-dose Sputnik V vaccine is 97% effective against hospitalisation caused by the Omicron variant of coronavirus (B.1.1.529) among those vaccinated with 3 or 4 components (re-vaccination with Sputnik Light or Sputnik V after Sputnik V).

The study was conducted from 11 January to February 21, 2022 involving over 1,000 patients in Moscow. Sputnik V showed high efficacy against hospitalisation at 85.9% among patients vaccinated with at least one component.

To date, Sputnik V has been authorized in 71 countries with a total population of over 4 billion people, and Sputnik Light has been approved in more than 30 countries. The Russian Direct Investment Fund invested in development and production of both Sputnik V and Sputnik Light.

Efficacy among those vaccinated with 3 or 4 components (re-vaccination with Sputnik Light or Sputnik V after Sputnik V) rose to:

97% against any cases of hospitalisation;

97.7% against moderate-severe and more severe cases;

98.6% against severe and critical cases;

99.4% against critical cases.

As authors note, “the study shows that vaccination with Sputnik V and Sputnik Light has a high effectiveness for protection against hospitalisation. The reduction in the severity of COVID-19 regarding the Omicron variant was also observed. The greatest effectiveness was evident in protection against a critical course of the disease requiring patients to be admitted to the intensive care unit.”
