Two new studies published Wednesday report good news about the updated Covid-19 vaccine, with one suggesting it is more effective than the previous monovalent vaccine and the other showing that even though it targeted an earlier strain of the SARS-CoV-2 virus, its protection is holding up against current variants.
The findings suggest the updated vaccine, which targets both the original SARS-2 virus and the Omicron subvariants BA.4 and BA.5, is performing better than some critics of the decision to update the vaccine concluded, based on studies that only compared the levels of neutralizing antibodies each induced.
The first study, published in the New England Journal of Medicine, found the updated vaccine was significantly more effective at protecting against severe illness, hospitalization, and death from Covid than the monovalent vaccine that was previously used.
“It’s clear from this study that the bivalent booster, in that short term following administration, provides additional protection above and beyond that of the monovalent,” said Michael Osterholm, director of the University of Minnesota’s Center for Infectious Diseases Research and Policy. “I think that’s clear and this should be a reason why we can feel confident that it was the right decision to go with the bivalent vaccine.”
