Relating to prohibited discrimination based on a child's immunization status; authorizing administrative penalties.

HB 3957 prohibits health care providers and facilities in Texas from denying treatment, services, or discriminating against children based on their immunization status for infectious or communicable diseases. It specifically bans doctors, nurses, and health care facilities from refusing care or creating policies that deny services due to a child's vaccination status, except during declared public health emergencies. The bill requires health care facilities to post clear notices about non-discrimination rights and allows parents to file complaints with state agencies (like the Texas Medical Board) for violations, with administrative penalties for repeated offenses. This law directly affects all health care providers serving children in Texas and aims to prevent discrimination in medical settings.
