imMTrax, Montana’s Immunization Information System (IIS), is a free program administered by the Montana Department of Public Health and Human Services (DPHHS) containing immunization records for participating Montanans of all ages.    imMTrax   brings together multiple immunization records from Montana healthcare providers (public and private) and parental “shot cards” to form   one complete, electronically preserved record . By sharing immunization records for mutual patients,   imMTrax  assists health professionals in making appropriate immunization decisions and ensuring Montanans are immunized on time, every time.

imMTrax  is only accessed by health professionals, local public health, and school personnel for authorized purposes.
