This bill mandates that the medical examiner's report for investigations involving infants aged zero to three years must include a request for information about the date and type of the decedent's last immunization. In cases where multiple immunizations were administered at that time, the report must detail all types of immunizations received.

Additionally, the bill requires the state medical examiner to adopt rules in accordance with chapter 17A to ensure compliance with these new reporting requirements. This aims to enhance the collection of immunization data in the context of child death investigations.
