CDC researchers looked at patient visits to hospitals and urgent care centers in 10 states.
An early look at the performance of COVID-19 booster shots during the recent omicron wave in the U.S. hinted at a decline in effectiveness, though the shots still offered strong protection against severe illness.
The researchers looked at patient visits to hospitals and urgent care centers in 10 states. They estimated how well Pfizer or Moderna booster shots prevented COVID-related visits to emergency departments and urgent care centers, and how well the vaccines prevented hospitalizations. Those results, however, were based on only a small number of patients — fewer than 200 — who had been boosted four months earlier at the time of the omicron wave. And it’s unclear if those people had gotten boosters early for medical reasons that may have made them more vulnerable to severe illness.
And from the beginning, vaccines have offered less protection against the omicron mutant than earlier versions of the virus. The study couldn’t address how protection will hold up against the next variant to come along.
