Hyderabad: The Gamaleya National Research Center of Epidemiology and Microbiology and the Russian Direct Investment Fund (RDIF), Russia's sovereign wealth fund, on Monday announced strong results of the study on neutralizing the activity of sera from individuals vaccinated with Sputnik V vaccine against new variants of SARS-CoV-2.


The company said vaccination with Sputnik V has produced protective neutralizing titers against new variants, including Alpha B.1.1.7 (first identified in the UK), Beta B.1.351 (first identified in South Africa), Gamma P.1 (first identified in Brazil), Delta B.1.617.2 and B.1.617.3 (first identified in India) and Moscow endemic variants B.1.1.141 and B.1.1.317 with mutations in the receptor-binding domain (RBD).


"The methodology was based on the assessment of virus-neutralizing activity (VNA) using the live virus, which provides the most reliable data and is the gold standard. It compared neutralizing activity of Sputnik V induced sera to the internationally relevant variants with the neutralizing activity to the ancestral B.1.1.1 variant. The sera were obtained from individuals after vaccination with two doses of Sputnik V," the company said.
