N.J. Stat. Ann. § 26:1A-9.1

Provisions in the State Sanitary Code in implementation of this act shall provide for exemption for pupils from mandatory immunization if the parent or guardian of the pupil objects thereto in a written statement signed by the parent or guardian upon the ground that the proposed immunization interferes with the free exercise of the pupil's religious rights. This exemption may be suspended by the State Commissioner of Health during the existence of an emergency as determined by the State Commissioner of Health.
