This bill mandates that the medical examiner's report for investigations involving infants aged zero to three years must include a request for detailed information about the decedent's last immunization. Specifically, it requires the inclusion of the date and type of the last immunization received, and if multiple immunizations were administered at that time, all types must be documented.

Additionally, the bill stipulates that the state medical examiner is responsible for adopting rules in accordance with this new requirement, ensuring that the process aligns with existing regulations under chapter 17A. This legislative change aims to enhance the data collected during medical investigations of young children, potentially aiding in public health assessments and responses.
