About CIIS

What is the Colorado Immunization Information System?

Also known as Colorado’s immunization registry, the Colorado Immunization Information System (CIIS) is a confidential, computerized, population-based system that collects and consolidates vaccination data from vaccine providers and provides tools for designing and sustaining effective immunization strategies at the provider and program levels. Operated by the Colorado Immunization Program at the Colorado Department of Public Health and Environment, CIIS helps healthcare providers, schools, childcare centers, universities, and individuals keep track of the shots that they and/or their children have received.

Why is this important?

The schedule of shots that is necessary for you/your child to stay healthy and required for your child to attend school, daycare, camp and university becomes more complicated with every new vaccine development. Keeping all the shots in one place, and on one record, helps ensure that you and your child get the complete schedule of immunizations – no more and no less.

What information about me/my child will be entered into CIIS?

The shots that you/your child have already received and any vaccines that you/your child will receive in the future will be entered into CIIS. Other information, including mother’s name (for individuals under 18 years of age), gender, and the office where each shot is given will be included in the registry to be sure that your/your child’s record is accurate and cannot be confused with another patient’s record. Your address will also be included in the system to allow your healthcare provider to send you a card to remind you when you/your child are due for an immunization. All information entered into CIIS is secure and confidential. For more details on the CIIS confidentiality policy, please visit the Confidentiality page.
