History of ImmTrac2

The 78th Legislature in 2003, passed House Bill 1921. The bill strived to clarify immunization registry components to:

  • Reduce confusion about parental consent.
  • Increase provider and client participation.
  • Protect the privacy and confidentiality of registry data.
  • Increase the utility of the registry and registry data. 
  • Transition from requiring a written signature on the provider registration and renewal form to allowing the use of an online form.

DSHS implemented House Bill 1921 in 2005. The bill’s key requirements:

  • All healthcare providers and payors must report to ImmTrac all vaccines given to children under 18 years old.
  • While registering for a birth certificate, parents can grant consent to participate in the registry or can request exclusion from the registry.
  • A parent may submit a child's immunization history to ImmTrac for inclusion in the registry.


The 80th Legislature passed Senate Bill 11 in 2007, changed the process for receiving parental consent, and added first responders and adverse vaccine reactions.

  • Authorized ImmTracusers were now able to affirm to DSHS that they received written parental consent without actually submitting the paper form.
  • ImmTraccould include immunization information on first responders (peace officers, fire protection personnel, emergency medical services personnel) and their immediate family members 18 years of age and older. The registry now captured information about people who get an immunization, antiviral, or other medication given in preparation for a potential declared disaster, public health emergency, or in response to such an event.
  • ImmTrac began tracking adverse reactions to an immunization, antiviral, or other medication given in preparation for a potential declared disaster, public health emergency, or in response to such an event.


During the 81st Legislature, Senate Bill 346 passed and changed the registry from a children's-only registry to a lifetime registry (enrollment from birth to death), allowing Texans aged 18 years or older to store their immunization records in the registry. In 2011, ImmTrac implemented the new legislation and began promoting the registry and adult consent requirements. Adults may grant consent at any time to participate in ImmTrac, and consent is valid for a lifetime.


During the 84th Legislature, in 2015, House Bill 2171 passed. It extended the time for maintaining information in the immunization registry after an individual becomes an adult, from 18 to 26 years of age. 

On April 3, 2017, DSHS Immunization Unit replaced ImmTrac with the Texas Immunization Registry, the enhanced ImmTrac2. The new system includes upgrades for immunization users, including enhanced immunization history and forecasting capabilities, client and immunization de-duplication, and report-generating capabilities.  

Currently, the registry is one of three programs at the DSHS participating in the stages of Meaningful Use (MU) as defined by the Centers for Medicare and Medicaid Services Electronic Health Record (EHR) Incentive Programs. Meaningful Use is in its second of three stages.
