 Immunization

Colorado law requires that the Colorado Department of Public Health and Environment— Certificate of Immunization be completed and provided to your child’s school. The law requires documentation of immunizations or a signature on file exempting the child for medical, religious, or personal reasons(C.R.S. 25-4- 903).

The following requirements are effective for the coming school year:

  • Two doses of MMR (Measles, Mumps, Rubella) vaccine are required for all students grades K –12.
  • Three doses of Hepatitis B vaccine are required for all students grades K – 12.
  • Varicella, (chicken pox). All  sixth grade and seventh grade students are required to have either, a laboratory test showing immunity or a disease history from a health care provider.
  • Tdap (tetanus, diphtheria, and pertussis) is required for 6th graders
