Alternative Schedules: Resources & Information

The U.S. childhood immunization schedule is reviewed and approved by CDC, American Academy of Pediatrics, American Academy of Family Physicians, and American College of Obstetricians and Gynecologists. Alternative vaccination schedules have not been tested, reviewed, or approved by any medical authority or public health group. Alternative schedules delay induction of immunity and leaves children vulnerable to vaccine-preventable diseases.
