US to hold push for Covid boosters until fall in order to better protect against BA.5

Pfizer and Moderna expected to roll out reformulated boosters, likely to be authorized for anyone 12 and older, in September

Instead of expanding eligibility for a fourth Covid-19 booster shot now, the Biden administration will push this fall to get Americans to take another booster vaccination that is predicted to better protect against the Omicron BA.5 subvariant of the coronavirus.

Pharmaceutical companies Pfizer and Moderna are expected to start rolling out the reformulated boosters, which are expected to be authorized for anyone 12 and older, in September.
