Relating to the immunization data included in and excluded from the immunization registry.

HB 772 modifies Texas' immunization registry rules to clarify patient consent and exclusion processes. It requires healthcare providers to obtain written or electronic consent before adding immunization data to the registry, and allows individuals or their representatives to request exclusion at multiple points (e.g., during birth, after each vaccination, or online). Once excluded, individuals need not re-request exclusion, and the registry must include clear instructions on how to opt out. The bill directly affects all Texas residents receiving vaccinations, as it governs how their immunization data is collected and managed within the state's public health system. The changes focus solely on data privacy procedures, not vaccination requirements or public health policies.
