Researchers from the University of Washington and the Swiss manufacturer Humabs Biomed SA have analyzed the efficacy of six vaccines against the highly contagious and most mutated variant of COVID. Only three of the 13 subjects given both doses of Sinopharm injections showed neutralizing antibodies against omicron. For J&J, this scale fell to one in 12 samples. None of the 11 people fully vaccinated with Sputnik produced such antibodies.
The study, which was published as a manuscript prior to peer review, also found that reduce antibodies Hama comes from a combination of Previous infection and two doses of Pfizer mRNA vaccines. Antibody levels in this subgroup of people increased fivefold, compared to 44 times for those who took two Pfizer vaccines but had no history of COVID infection.
