Immunization Information


Colorado law requires all students attending Colorado schools and licensed child cares to be vaccinated against certain diseases, unless an exemption is filed. Below are the vaccines required for students attending Colorado licensed child cares and schools.  

Vaccines required to enter school (K-12)  

  • Hepatitis B.  
  • Diphtheria, tetanus, pertussis (DTap).*  
  • Inactivated poliovirus (IPV).*  
  •  Measles, mumps, rubella (MMR).*  
  • Varicella (chicken pox).*  
  • Tetanus, diphtheria, pertussis (Tdap).**  

*Students 4 through 6 years of age are required to have their final doses of DTaP, IPV, MMR and Varicella prior to kindergarten entry.  

**Students are required to have Tdap prior to entry into 6th grade. One dose of Tdap is required for 6th through 12th grades. 

If you choose not to have your student vaccinated according to the current recommended schedule because of personal or religious reasons, you must submit a Certificate of Nonmedical Exemption to AVA when school begins in August.  

Nonmedical exemptions must be submitted annually, which means parents must submit the certificate every new school year. (The school year begins on July 1 and runs through June 30 of the following year.) There are two ways to file a nonmedical exemption:

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 the online education module.

Downloadable certificates and the online education module are available at
