• Welcome to the MIIS

    The Massachusetts Department of Public Health Immunization Program is committed to promoting the health of Massachusetts' citizens by reducing the burden of vaccine preventable diseases that affect the residents of the Commonwealth. As part of this effort, in 2011 the MDPH Immunization Program launched the Massachusetts Immunization Information System (MIIS), a web-based immunization registry. The MIIS is in the process of being rolled out statewide and once fully implemented will be the official source of immunization information for Massachusetts.
