Under Colorado law, you can remove your/your child’s immunization information from the Colorado Immunization Information System (CIIS) at any time. This is called an opt-out. If you change your mind, you can have your health care provider re-enter your/your child’s immunization record into CIIS at a later time by submitting a rescind opt-out form.
If you choose not to participate in CIIS, you're responsible for keeping track of your/your child’s immunization record.
Colorado Revised Statute (CRS) § 25-4-2403 (7) provides that an individual or a parent or legal guardian has the right to exclude immunization information from the Colorado Immunization Information System (CIIS).
