COVID vaccine: CDC expands booster rollout, OKs mixing shots

Virus Outbreak Boosters

WASHINGTON (AP) — Millions more Americans can get a COVID-19 booster and choose a different company’s vaccine for that next shot, federal health officials said Thursday.

Certain people who received Pfizer vaccinations months ago already are eligible for a booster and now the Centers for Disease Control and Prevention says specific Moderna and Johnson & Johnson recipients qualify, too. And in a bigger change, the agency is allowing the flexibility of “mixing and matching" that extra dose regardless of which type people received first.

The Food and Drug Administration had already authorized such an expansion of the nation's booster campaign on Wednesday, and it was also endorsed Thursday by a CDC advisory panel. CDC Director Dr. Rochelle Walensky had the final word on who gets the extra doses.

“These past 20 months have taught us many things, but mostly to have humility," she told the panel. "We are constantly learning about this virus, growing the evidence base and accumulating more data.”
