Scientists of Spallazanian Institute in Italy proved that the Vaccine “Satellite V” provides a higher protection against the Omicron-option SARS-COV-2 than Pfizer. The virus ethibrous activity of the Russian vaccine exceeds the American RNA-vaccine figure more than twice. This was reported in a press release, which was sent to the editor of the “Lental.ru”.
According to the results of comparative studies, the Vaccine “Satellite V” showed twice the larger titer of neutralizing antibodies to the strain B.1.1.529 and 2.6 times higher – three months after vaccination. The Russian vaccine neutralizes the Omicron strain due to the formation of a strong immune response due to the high level of antibodies. In 100 percent of the vaccinated “satellite V”, antibodies were recorded, effectively neutralizing a new omikron strain, compared with 83.3 percent in vaccinated Pfizer.
According to experts, this is due to the fact that due to the “satellite V” generates a wider spectrum of virus-violent antibodies, in contrast to the Pfizer vaccine, affecting the specific S-protein epitopes, strongly distorted by mutations in the Omicron strain. Since 80 percent of epitopes in S-protein, recognized by T-cells CD8 +, are not affected by mutations in the Omicron version, “satellite V” forms a strong and long-term T-cell immune response and is expected to provide long-term protection against severe cases and hospitalization. .
