Millions more Americans are closer to getting a COVID-19 booster as influential government advisers on Thursday endorsed extra doses of all three of the nation’s vaccines — and opened the possibility of choosing a different company’s brand for that next shot. Certain people who received Pfizer vaccinations months ago already are eligible for a booster and now advisers to the CDC say specific Moderna and Johnson & Johnson recipients should qualify, too. And in a bigger change, the panel allowed the flexibility of “mixing and matching” that extra dose regardless of which type people received first.
