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

SB 46 modifies Texas' state immunization registry rules to clarify which vaccination data can be included and how individuals can opt out. It requires healthcare providers to obtain initial consent (once for adults) before adding immunization records, while giving individuals or parents/guardians multiple ways to request exclusion - such as at birth, during appointments, online, or via written request. The bill ensures people aren’t required to repeatedly opt out and mandates that exclusion requests are honored until a new written request for inclusion is submitted. This directly affects Texas residents, parents/guardians of minors, and healthcare providers who report immunization data to the state registry.
