MIIS Registration

The Massachusetts Immunization Information System (MIIS) is hosted by the Executive Office of Health and Human Services Virtual Gateway (VG). To gain access to the MIIS, providers must complete registration for both the MIIS and the VG for the site, as well as individual users. We have integrated both registrations into one process, which can be completed online through this website.
