Pfizer Says Booster Lifts Antibodies For Omicron Variants

“While we expect more mature immune-response data from the clinical trial of our omicron BA.4/BA.5-adapted bivalent vaccine in the coming weeks, we are pleased to see encouraging responses just one week after vaccination in younger and older adults,” Pfizer Chief Executive Albert Bourla said in the statement. “These early data suggest that our bivalent vaccine is anticipated to provide better protection against currently circulating variants than the original vaccine, and potentially help to curb future surges in cases this winter.”
