A group of scientists led by a biochemist from the Center for Cancer Research in Seattle (USA) Tyler Starr has discovered an antibody that can fight not only various variations of SARS-CoV-2, but also other coronaviruses. This is stated in an article in the scientific journal Nature.
Scientists have conducted studies of the antibodies of those who have been ill, and have also compiled a list of thousands of mutations in the domains of various variants of COVID-19 and other coronaviruses.
It turned out that one of the antibodies (S2H97) was able to attach to the domains of all such pathogens and neutralize them in living cells.
According to scientists, the universal antibody effectively fights all variants of the coronavirus. However, it cannot be said with certainty that S2H97 will be able to protect against future SARS-CoV-2 mutations. But his research could help scientists create a vaccine that works against all strains of COVID-19.
Earlier, Vaccines magazine wrote an article claiming that the Russian Sputnik V coronavirus vaccine is capable of protecting against new strains of SARS-CoV-2. It follows from the article that vaccination with “Sputnik V” produces protective neutralizing antibody titers against strains that have become widespread in Russia: “alpha” (B.1.1.7, British), “beta” (B.1.351, South African), “gamma ”(P.1, Brazilian),“ delta ”and its mutations (B.1.617.2 and B.1.617.3, Indian). The drug is also effective against the variants identified in Moscow – B.1.1.141 and B.1.1.317 with mutations in the receptor binding domain (RBD).
