UPDATE: Changes in School Immunization Requirements effective October 1, 2015

The 2015 Montana Legislature revised school immunization requirements for school attendance through the passage of House Bill (HB) 158. The law, signed by the Governor and effective October 1, 2015, requires students attending school be vaccinated against varicella disease (chickenpox) and receive a booster of pertussis vaccine at 7th grade.

Varicella (Chickenpox) Vaccine:

Students in kindergarten through 12th grade will need to have two doses of varicella vaccine. (Please see below for Immunization Clinic hours)


If your child has had the chickenpox virus you may submit documentation by having your medical provider complete the approved History of Varicella form. The form can be found at your child’s school or by clicking here.
