Immunization Information

Colorado law (Board of Health rule 6 CCR 1009-2) requires all students attending Colorado schools (grades k-12) and child cares (preschools/Head Start) to be immunized against certain diseases, unless an exemption (medical or non-medical) is filed with the school. The minimum number and spacing of doses is set forth in the 2017 Advisory Committee on Immunization Practices (ACIP) Child and Adolescent Immunization Schedules.

Meeting the initial vaccine requirements does not excuse a student from meeting additional immunization requirements. Students not meeting vaccine requirements will be denied attendance in accordance with Colorado Revised Statutes 25-4-902.

In addition to the vaccines required for school entry, there are several vaccines recommended by the ACIP that provide protection against other diseases. These include Rotavirus, Meningococcal, Hepatitis A, Human papillomavirus and Influenza.

  • Diptheria, tetanus & pertussis (DTaP, DT, DTP, Tdap)
  • Polio (IPV/OPV)
  • Measles, mumps, rubella (MMR)
  • Hepatitis B (HepB)
  • Varicella (chickenpox)
  • Haemophilus influenzae type b (Hib) – not required after age 5
  • Pneumococcal Disease (PCV13) – not required after age 5
