Health: immunizations; certain information used in promulgating rules on immunizations; provide for. Amends sec. 9227 of 1978 PA 368 (MCL 333.9227). TIE BAR WITH: HB 5353'25

HB 5351 amends Michigan's Public Health Code to update how the state health department creates rules for childhood immunizations. It requires the department to consider recommendations from major health organizations like the CDC, American Academy of Pediatrics, and others when setting immunization rules, including minimum ages, doses, and school requirements. If recommendations from these groups conflict, the department must consult Michigan's advisory committee on immunizations. The bill also mandates that immunization requirements stay at least as strict as those in effect on January 1, 2025, if federal guidelines change. This bill directly affects the health department's rulemaking process and impacts schools, healthcare providers, and families managing childhood vaccination schedules.
