Vaccine exemptions

Colorado law requires all students attending Colorado schools and licensed child cares to be vaccinated against certain diseases unless they have a certificate of medical or nonmedical exemption on file. You must file a certificate of exemption at each school, or child care the student attends. To protect unvaccinated children, students with an exemption from one or more required vaccines may be kept out of a school or child care during a disease outbreak.

Medical exemptions

  • Students with a complete certificate of medical exemption (signed by a medical doctor, doctor of osteopathic medicine, advanced practice nurse or delegated physician's assistant) need to file this certificate only once unless the student’s information or school changes.
  • You can file a certificate of medical exemption with us to include in the Colorado Immunization Information System (CIIS). Check with your child's school or child care to find out whether it needs a paper copy of the certificate of medical exemption. Or, you can file the certificate with your child’s school or child care.
  • Per Colorado Revised Statutes 25-4-2403(2.5), immunizing providers must submit medical exemption data to CIIS.

    • File the certificate of nonmedical exemption WITH a signature from an immunizing provider, OR
    • File the certificate of nonmedical exemption received upon the completion of our online education module.
    • Parents of students in grades K-12 claiming a nonmedical exemption must file one annually. Nonmedical exemptions expire June 30 each year. If you submit a nonmedical exemption on or before June 30, it will not be valid for the upcoming school year unless you signed the exemption during early registration.
    • Parents of students in preschool or child care must file nonmedical exemptions at 2, 4, 6, 12 and 18 months of age. These exemptions expire when the next vaccines are due or when the child enrolls in kindergarten.
