Study finds high levels of omicron-fighting antibodies four months after Pfizer booster | TheHill - The Hill

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.

There 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.

There is still an open question as to how long protection from a booster shot will last beyond four months
