For all the coronavirus variants that have thrown pandemic curve balls — including alpha, beta, gamma and delta — COVID-19 vaccines have stayed the same. That could change this fall.
On June 28, an advisory committee to the U.S. Food and Drug Administration met to discuss whether vaccine developers should update their jabs to include a portion of the omicron variant — the version of the coronavirus that currently dominates the globe. The verdict: The omicron variant is different enough that it’s time to change the vaccines. Exactly how is up in the air; the FDA still has to weigh in and decide what versions of the coronavirus will be in the shot.
“This doesn’t mean that we are saying that there will be boosters recommended for everyone in the fall,” Amanda Cohn, chief medical officer for vaccine policy at the U.S Centers for Disease Control and Prevention said at the meeting. “But my belief is that this gives us the right vaccine for preparation for boosters in the fall.”
