Sudden death; require medical examiners to report vaccinations and emergency countermeasures within 90 days prior to.

SB 2457 requires medical examiners in Mississippi to review and document an infant or child’s vaccination records and emergency medical treatments administered within 90 days before sudden, unexpected deaths (including SIDS, SUID, or SDY cases). It mandates that autopsies include toxicology and microscopic studies, with findings reported to the national SUID/SDY Case Registry if the deceased was under age 20. Failure to report such cases within 30 days incurs escalating fines (up to $10,000 for repeat offenses). The bill also clarifies that compliance with these reporting rules is permissible under medical privacy laws like HIPAA. This legislation died in committee on February 3, 2026, and has not advanced further.
