A study from the Gamaleya National Research Center for Epidemiology and Microbiology in Moscow, published this Monday in the scientific journal Vaccines, shows that the Russian vaccine Sputnik V is effective against new variants of the coronavirus.
In particular, the research concluded that Sputnik V vaccination “produces protective neutralizing antibody titers” against variants such as Alpha B.1.1.7 (first identified in the UK), Beta B.1.351 (identified in South Africa), Range P.1 (in Brazil), Delta B.1.617.2 Y B.1.617.3 (in India) and B.1.1.141 Y B.1.1.317 (in Moscow, Russia).
“The data obtained show that Sputnik V retains its protective properties in front of the new strains [del coronavirus]”, communicated the Russian Direct Investment Fund (RDIF).
Besides, the decreased level of neutralizing activity of the virus [por parte] of Sputnik V, compared to various variants, turned out to be significantly lower compared to the data published by the manufacturers of other vaccines“.
To assess the continuity of neutralizing activity, the study was based on live viruses, which allows more reliable data to be obtained. In the course of the investigation, this effectiveness was compared in human blood serum after vaccination with both components of Sputnik V, in samples of variants of international distribution, with respect to the neutralizing activity against the original B.1.1.1.
From the RDIF they also stressed that the Gamaleya Center is actively studying new strains of covid-19 to evaluate the efficacy of its vaccine, and is also considering the possibility of creating drug “cocktails”, together with other manufacturers, using the first component of Sputnik V.
Sputnik V is currently registered in 67 countries, which cover a total population of more than 3.5 billion people. The data supplied by the regulators of several of them, including Mexico, Argentina, Serbia, Hungary, San Marino, United Arab Emirates, Bahrain and others, and obtained during the respective vaccinations, show that the Russian vaccine is one of the safest and most effective against the coronavirus, the RDIF specified.
