A leading scientist at the research institute that developed the product said that the Russian satellite V is less effective on the South African variant of covida-19, but the decline is smaller than other vaccines.
Alexander Gintsburg told Interfax: “As far as the South African variant is concerned, the effectiveness of the antibodies produced by Sputnik V is declining, as with all other vaccines.”
Gintsburg said in an interview that Sputnik V has tested the British and South African variants in laboratories in the United States, as well as the original strain that was first discovered in Wuhan, China.
He explained that the laboratory used blood samples from people infected with COVID-19 in Argentina.
He added that Russian scientists did not participate in those tests.
Gintsburg said that although the antibody response to the South African variant was weak, the decline was significantly smaller than that of other vaccines.
He said that the results of testing Sputnik V on a strain in Wuhan confirmed the findings of his team at the Gamaliya Institute in Moscow.
Gintsburg said: “It also shows that of all the vaccines currently in use in the world, Sputnik V…can best neutralize what we call the British variant.”
