Connecticut State Department of Public Health

The Connecticut Immunization Registry and Tracking System (CIRTS), is a FREE statewide, computerized program established and maintained at the Connecticut Department of Public Health for the purpose of assuring timely childhood immunizations. The Registry includes such information as is necessary to accurately identify a child and to assess current immunization status. CIRTS can:

  • Keep permanent records of children’s shots
  • Let doctors keep track of their children’s immunization histories in a computerized database
  • Give parents their children’s immunization histories for daycare, school, and camp
  • Provide parents with immunization information in the future even if they move away from Connecticut or their baby’s doctor retires
All personal information including vaccination status and dates of vaccination 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.
