HB 5044 Connecticut House · 2026 Regular Session

AN ACT ESTABLISHING CONNECTICUT VACCINE STANDARDS.

HB 5044 establishes Connecticut's official vaccine standards for children and infants, requiring the Commissioner of Public Health to create and maintain a standard of care based on CDC and medical association guidelines. This standard, posted online, will guide vaccination schedules and safety protocols, and must be updated as needed. The bill also mandates a state immunization program that provides free vaccines to healthcare providers for children, distributes vaccination schedules to parents at hospital discharge, and develops outreach to help children who fall behind on immunizations. It directly affects children (especially infants), healthcare providers, hospitals, and public health departments. The program must use available state and federal funds to support these services without creating new state regulations.
