The requirement to cover shots began immediately for the updated fall 2023 shots after they were greenlighted by the Food and Drug Administration, officials said, erasing a monthslong grace period private insurance companies typically have to implement new vaccines.
It does look like they are trying to put something into place (Bridge Access Program that would entail funding vaccine programs) and they are encouraging private insurers to pay for shots as they do other vaccines. I would hate for cost to be a barrier for those who want it!
