Health: immunizations; Michigan care improvement registry; ensure that users have access to certain data. Amends secs. 9201 & 9207 of 1978 PA 368 (MCL 333.9201 & 333.9207).

HB 5346 amends Michigan's Public Health Code to update access to the Michigan Care Improvement Registry (formerly the Childhood Immunization Registry). It requires the state department to allow users to query and extract immunization records by school building, directly affecting school health staff and administrators. The bill also adds a provision enabling individuals aged 20 or older to request that their personal immunization records be made inaccessible in the registry upon submitting a written request. These changes focus on improving data accessibility for school-based health management while enhancing privacy options for adult patients.
