New Hampshire RSA 141-C:20-c states that a child may be exempt from required school and child care immunization if:
A licensed physician or authorized health care provider certifies that immunization against a particular disease may be detrimental to the child's health. The exemption shall exist only for the length of time, in the opinion of the physician, such immunization would be detrimental to the child. An exemption from immunization for one disease shall not affect other required immunizations. This is a Medical Exemption.
A parent or legal guardian objects to immunization because of religious beliefs. The parent or legal guardian shall sign a notarized form stating that the child has not been immunized because of religious beliefs. This is a Religious Exemption.
