Maryland is set to undergo a significant shift in its approach to vaccine recommendations and other preventive health guidelines, under the "Vax Act". The law allows the state health secretary to determine which vaccines and preventive services are recommended in Maryland. The move is seen as a move away from reliance on federal guidance, including recommendations from the Centers for Disease Control and Prevention (CDC). Critics argue that the shift could create confusion for families and health care providers if state and federal guidance diverge. The state will still consult major medical organizations, including the American Academy of Pediatrics, for guidance.
