A new study shows high levels of coronavirus antibodies that fight the omicron variant four months after a third dose of the Pfizer vaccine, a positive sign for the durability of a booster shot’s effectiveness.
The study from researchers at Pfizer, BioNTech and the University of Texas Medical Branch shows virus-fighting antibodies enduring four months after the third dose, helping answer the key question of how long protection from the booster shot lasts.
Eric Topol, professor of molecular medicine at Scripps Research, tweeted in response to the study that antibody levels were “unexpectedly still quite high” after four months, “which is great.”
here was still some decline in antibody levels between one month and four months after the third dose, but the amount of decline against omicron was similar to that against the original strain of the virus, Pfizer said.
Pei-Yong Shi, one of the authors of the study at the University of Texas Medical Branch, told The Washington Post that the study “shows that at least up to four months, post-dose three, there is still substantial neutralizing activity against omicron.” ...
