a us executive order directed the cdc and the federal vaccine advisory board to align with an hhs assessment calling for reduced childhood vaccine recommendations, and separately a major obstetrician-gynecology society publicly broke from cdc guidance on covid and other vaccines for pregnant women. this is two simultaneous fractures in us vaccine governance \u2014 one from the executive pushing the agency to change its schedule, one from a professional body refusing to follow the agency. when the rule-setting body, the executive, and the medical profession diverge at the same moment, the official recommendation stops being a single number.
