The Texas Immunization Registry, better known as ImmTrac, is a no-cost service offered by the Texas Department of State Health Services (DSHS). It is a secure and confidential registry available to all Texans. ImmTrac safely consolidates and stores immunization information from multiple sources electronically in one centralized system. Texas law requires written consent for ImmTrac participation and limits access to the registry to only those individuals who have been authorized by law. ImmTrac contains over 120 million immunization records and continues to rapidly grow with increased participation.

The immunization information in ImmTrac is provided by a variety of sources, including private health-care providers, pharmacies, public health clinics, Medicaid claims administrators, and the Vital Statistics Unit (VSU). Regardless of the number of sources, each client’s immunization information is consolidated into one electronic record. Authorized professionals such as doctors, nurses, and public health providers can access clients’ vaccination histories.

Records include the participant's name and address, the name of the parent or guardian (if applicable), information on the shots given, and who gave them. Medicaid numbers are also included if participant is enrolled in the program. Other information, such as the Social Security number may be provided with consent.

How does ImmTrac protect my child?

Providers authorized to use ImmTrac can see what immunizations your child has already had, even if they were given in another city or country. So when you come in for shots, your child gets only those that he or she needs.

This means that your child won't be under-vaccinated and more susceptible to diseases. Your child won't be over-vaccinated either, so he or she does not have to go through any more discomfort than is necessary.

ImmTrac can also print out a shot record you can use to get into school or daycare.

Using ImmTrac, immunization providers can remind you to bring your child in for shots that are due, or to notify you about shots that are overdue.

How can I get my child's immunization records into ImmTrac?

Participation in ImmTrac is voluntary. To have your shots put into the database, talk to the clerk who is completing your birth certificate. Or, when you take your child to a clinic or to the doctor's office for shots, ask if they use ImmTrac or send their shot records to ImmTrac. If they do, give them your consent to have your child's records put into ImmTrac.
