The study found that after a booster vaccination, levels of antibodies in the blood that could bind to and neutralize a new omicron variant increased substantially. FOX13
may provide protection against a subvariant of omicron – the variant which has rapidly become the dominant strain in the world and currently accounts for most cases of the virus in the U.S.
The team tested antibodies from the blood of 24 people who had been vaccinated and boosted with the Pfizer shot. In addition, they looked at antibodies from eight people who had recovered from COVID-19, seven of whom had also been vaccinated. According to the study, the number of antibodies that could recognize BA.2 was even higher in people who had been vaccinated and infected with the original omicron variant. The one person who had no detectible neutralizing antibodies in their blood after exposure to COVID-19 hadn’t been vaccinated.
