More Veterans Vaccine Clinics in Montana The Montana Veterans Administration Health Care System (MTVAHCS) is scheduling Moderna vaccinations around the state for Veterans, their spouses, caregivers and CHAMPVA recipients. The Department of Veteran's Affairs has expanded the program to include all Veterans, regardless of their VA health care enrollment status, along with Veteran spouses, caregivers and some beneficiaries. Veterans who have not yet received vaccinations are encouraged to call the MTVAHCS to schedule an appointment at 877-468-8386 and select Option 2, and then select Option 2. Non-veterans who are eligible to receive a MTVAHCS vaccine can sign up online. After registering online, the Montana Health Care Service will contact the non-enrolled Veterans, spouses and caregivers to schedule an appointment.
