Massachusetts Immunization Information System (MIIS)

The Massachusetts Immunization Information System (MIIS) is a web-based immunization registry.

The Massachusetts Department of Public Health (MDPH) Immunization Division is committed to promoting the health of Massachusetts' residents 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 Division launched the MIIS. All providers who administer immunizations in Massachusetts are mandated to report immunization data to the MIIS.
