Immunizations and Exemptions 2023 - 2024

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 year between July 1st and August 31st.
2023 - 2024 Exemption Information

There are two ways to submit a nonmedical exemption. 

Be sure to check with your student’s school, child care, or college/university to find out if they need a printed copy of the Certificate of nonmedical exemption. If you submit to CIIS, the school can access the exemption information in CIIS, but cannot access the completed Certificate of nonmedical exemption

  • Submit the Certificate of nonmedical exemption WITH a signature from an immunizing provider in Colorado who is a medical doctor, doctor of osteopathic medicine, advanced practice nurse, delegated physician’s assistant, registered nurse, or pharmacist OR
  • Submit the Certificate of nonmedical exemption received upon the completion of CDPHE’s Online Immunization Education Module.
  • Parents of students in grades K-12 claiming a non-medical exemption must submit one annually. Nonmedical exemptions expire June 30th each year. If you submit a Certificate of nonmedical exemption on or before June 30th, it will not be valid for the upcoming school year unless you submit the exemption during early registration.
