CIIS helps healthcare providers, schools, childcare centers, universities, and individuals keep track of the shots that they and/or their children have received.
CIIS is a program within the Colorado Immunization Section at the Colorado Department of Public Health and Environment (CDPHE). CIIS is a lifelong immunization record tracking system under the Colorado Immunization Registry Act of 2007.
