Summary — HB 4552 (2025)

Status: House introduced 03/12/2025; bill text electronically reproduced 06/05/2025. Introduced by Rep. Brad Paquette. Tie-bar: HB 4553 of 2025. If enacted, takes effect 90 days after enactment and is conditional on enactment of SB ___ or HB 4553.

Purpose / Intent

HB 4552 restricts state and local public health rulemaking and regulatory authority related to school and group‑program immunization exemptions and limits the ability to exclude students or program participants from attendance for communicable‑disease control in non‑epidemic circumstances.

Key provisions

  • Adds MCL 333.5115a:

    • Prohibits the Michigan Department of Health and Human Services (MDHHS) from promulgating or enforcing any rule that would allow a local health officer who confirms or reasonably suspects an individual in a school or recognized “group program” has a communicable disease to exclude that individual from attendance as a disease‑control measure where the situation is not an epidemic.
    • Rescinds Michigan Administrative Code rule R 325.175.
  • Amends MCL 333.9215 (school immunization exemptions):

    • Confirms medical exemption where a physician certifies a given vaccine is or may be detrimental to a child.
    • Preserves nonmedical exemptions: a parent, guardian, or person in loco parentis can submit a written statement to the school/operator asserting religious convictions or other objections to immunization.
    • Prohibits MDHHS from promulgating or enforcing rules that impose different or additional requirements for claiming these exemptions, or requiring exemptions to be on a form prescribed by the department.
    • Prohibits local health departments from adopting/enforcing regulations that impose different/additional requirements for these exemptions or require department‑prescribed forms.
    • Requires that if the department provides public information about these exemptions, it must also include information on vaccine effectiveness and potential risks for required immunizations.
  • Amends MCL 333.9227 (rulemaking authority):

    • Retains MDHHS authority to promulgate rules to implement immunization requirements (ages, dose schedules, reporting, registry functions), but subject to the limitations above.

Who is affected

  • MDHHS and local health departments (limits on rulemaking/regulatory authority).
  • Schools, child care/group programs and their administrators (changes in exclusion authority and exemption processing).
  • Parents/guardians and students/children (easier ability to use existing medical or written nonmedical exemptions; potential reduced risk of exclusion in non‑epidemic cases).
  • Public health practice in schools and outbreak control (limits on exclusion as a control measure outside epidemics).

Procedural / timeline notes

  • Reported favorably (committee substitute) in late April 2025; committee reports filed in May 2025.
  • Enactment is conditioned: the act “does not take effect unless” SB ___ or HB 4553 of the 103rd Legislature is enacted.
  • If enacted, effectiveness is 90 days after the bill becomes law; rescission of R 325.175 would occur as part of that enactment.
