CIIS opt-out procedures
Under Colorado law, you have the option to exclude your/your child’s immunization information from the Colorado Immunization Information System at any time.
If you change your mind, you can always have your health care provider re-enter your/your child’s immunization record into CIIS at a later time.
If you choose not to participate in CIIS, you're responsible for keeping track of your/your child’s shot record.
If you choose to opt out of the Colorado Immunization Information System, please read the following instructions and follow all steps to ensure that your/your child’s immunization information is excluded from CIIS.
Upon your request to exclude immunization information from CIIS, your health care provider should:
Direct you to a Colorado Immunization Information System Opt-Out Form.
Attach one signed copy of the form to your/your child’s medical record in the location usually reserved for the immunization record, if applicable or practical for clinic work flow.
To complete the opt-out procedure, it's your responsibility to:
Mail or fax one signed copy of the CIIS Opt-Out Form to the CIIS office at the address found on the bottom of the form.
Keep one signed copy of the form for your records.
