In February 1997, the Committee on Bioethics of the American Academy of Pediatrics (AAP) updated its position on religious exemptions to medical care. In its earlier statement, the committee noted that forty-four states have religious exemptions to the child abuse and neglect statutes, and they argued for the repeal of these exemptions. The committee did not indude in its statement a position on religious exemptions to childhood immunization requirements that exist in forty-eight states, although this issue was discussed in committee meetings. In its revised statement, the committee concluded that “The AAP does not support the stringent application of medical neglect laws when children do not receive recommended immunizations.” In this paper, we consider whether failure to immunize one's child is a form of medical neglect and, if so, whether states should repeal their religious exemptions to the immunization statutes. We argue that failure to vaccinate a child properly is medical neglect.
