Health: immunizations; promulgation of certain rules that are more stringent than the requirements for claiming exemption from immunizations; prohibit. Amends sec. 9215 of 1978 PA 368 (MCL 333.9215).

HB 5634 prevents Michigan's health department from creating stricter rules or requiring additional paperwork for school immunization exemptions. It preserves only two existing exemption types: medical (certified by a physician) and religious/philosophical (via a parent's written statement). The bill explicitly blocks the department from mandating new exemption forms or imposing extra requirements beyond these two categories. This directly affects schools, parents seeking exemptions, and the health department's regulatory authority. The legislation maintains the current exemption framework without expanding or altering it.
