Connecticut Immunization Registry and Tracking System (CIRTS)


In 1994, the legislature authorized the Connecticut Department of Public Health (CT DPH) to establish the Connecticut Immunization Registry and Tracking System (CIRTS). CIRTS is a FREE statewide, immunization registry established and maintained at the CT DPH. The purpose of the registry is to assure that children remain up-to-date with their immunizations and that their records are available when needed. After a pilot period of several years, CIRTS became a statewide registry in 1998.


COMING THIS FALL! One Integrated System!

New Immunization Information System “CT WiZ”

The Connecticut Department of Public Health (DPH) Immunization Program will replace the Connecticut Immunization Registry and Tracking System (CIRTS) with a new Immunization Information System (IIS) called "CT WiZ".  CT WiZ will offer many new features! You will order your vaccines, report doses administered and track your inventory all in this one system. The IIS will enable bi-directional electronic data exchange between your electronic health record (EHR) and CT WiZ. You will be able to assess your immunization coverage rates in CT WiZ. We may be replacing CIRTS, but your favorite features will still be available for you and will be improved! You will be able to easily view and print official immunization certificates for schools, childcare, camps and even college. CT WiZ will allow you to access and electronically query your patients' previous immunization records into one consolidated record. CT WiZ includes up to date programming, called the “Recommender” which forecasts which vaccinations are invalid, due and overdue to help avoid under and over-vaccinations. These features and more are all part of the new CT WiZ.


To learn more about the new CT WiZ timeline and features you will be able to take advantage of in your clinic, school, or health department, please view the recorded webinar on the CT AAP website at:


Public Health requirements (state mandated) are independent of “Meaningful Use” (MU), now called Promoting Interoperability requirements, although there is overlap in content and standards. Efforts to achieve IIS-provider electronic data exchange will benefit providers for both public health and MU efforts. 


An Eligible Provider (EP) who routinely administers immunizations to children ages 0-6 years as part of the patient’s medical home and is mandated to report to the Connecticut Immunization Information System (IIS) is required to attest to the immunization registry public health reporting option in order to meet MU.

  • EPs can satisfy the Registration option for Active Engagement for Program Year 2017 for immunization reporting by completion and submission of the CT DPH Immunization Registration Form.  Please retain any confirmation material from DPH to validate the measure for Modified Stage 2.

  • Visit: Exceptions letter from DPH for Public Health reporting - Meaningful Use  Please note that Stage 2 immunization reporting, per state regulations, will only be for primary health care providers administering immunizations in an outpatient setting for children from birth to first grade.

All personal information including immunization status and dates of immunization of individuals shall be confidential as required by Connecticut law. Only the parent(s)/child’s legal guardian, child’s doctor, or health care workers who can assist with missed opportunities or missed immunizations have access to CIRTS.


Upon receiving a request from CIRTS, all healthcare providers administering immunizations to children in CT shall report those immunizations to CIRTS.
