CDC ACIP Meeting Today and Tomorrow: Covid-19 Vaccine Omicron Bivalent Booster Candidates

The CDC ACIP will meet today and tomorrow about the Covid-19 Vaccine Omicron Bivalent Booster candidates from Pfizer and Moderna. A vote is expected this afternoon.

Update: The committee voted by a majority to upvote the approval of the Pfizer and Moderna bivalent boosters this afternoon. There was one dissenting vote because there was no clinical data to present. There was a clinical study using the bivalent vaccine booster, but results would not have been available until November or December.

However, there was a complicated statistical predication model which showed that if the boosters were rolled out this month, many thousands of hospitalizations and deaths could be prevented as opposed to waiting a few more months. That got prioritized in order to approve the boosters now rather than wait for the clinical study results.

There was a lot of concern about the packaging of the boosters resembling other boosters which might lead to mistakes in administration. Pfizer has a booster vial that looks very similar to that of their bivalent Omicron booster, unless you closely read the tiny print on the vial which says it’s BA.4/BA.5.

The committee voted to cancel tomorrow’s meeting since they completed the goal today.
