Under the Affordable Care Act, most Americans would still get their Covid shots for free once the vaccine program goes commercial.
Currently, Pfizer’s and Moderna’s omicron shots are authorized as a booster, while the first two doses are still the old shots based on the original strain.
Pfizer said the booster triggered more antibodies against omicron BQ.1.1, BA.4.6, BA.2.75.2 and XBB.1 in adults older than 55 compared to the original vaccines.
The FDA pushed back against two independent studies that found the new boosters don’t trigger a better immune response than the old shots.
