quote:Booster shots of the Pfizer-BioNTech and Moderna vaccines lose substantial effectiveness after about four months — but still provided significant protection in keeping people out of the hospital during the omicron surge, according to a study published Friday by the Centers for Disease Control and Prevention.
Researchers found the booster shots remained highly effective against moderate and severe covid-19 for about two months after a third dose. But their effectiveness declined substantially after four months, suggesting the need for additional boosters, the study said.
The vaccine was 91 percent effective in preventing a vaccinated person from being hospitalized during the two months after a booster shot, the study found. But after four months, protection fell to 78 percent.
Protection faded more in preventing trips to urgent care and emergency departments, falling from 87 percent in the first two months to 66 percent after four months. After more than five months, vaccine effectiveness fell to roughly 31 percent, but researchers noted that estimate was “imprecise because few data were available” for that group of people.
