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 completed Certificate of medical exemption signed by an advanced practice nurse, a delegated physician assistant, or physician licensed to practice medicine or osteopathic medicine in any state or territory of the United States will need to submit this Certificate only once unless the student’s information or school changes.
  • You can submit a Certificate of medical exemption with CDPHE to include in the Colorado Immunization Information System (CIIS). Check with your student’s school, child care or college/university to find out if they want the printed copy of the Certificate of medical exemption or, if they can access the “submitted” document from CIIS.
  • Per Colorado Revised Statutes 25-4-2403(2.5), immunizing providers must submit medical exemption data to CIIS.
