Pfizer booster beneficial, study finds
Houston Chronicle, February 9, 2022
A third dose of COVID-19 vaccine provides robust protection against the omicron variant, according to research from a team of scientists at Pfizer, BioNTech and the University of Texas Medical Branch. The non-peer-reviewed study found that two doses of the Pfizer-BioNTech vaccine are insufficient to induce robust antibody neutralization against omicron, but a third increases the magnitude of neutralization. The effect remained robust at 4 months after the third dose, according to the study.
