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.
During online registration, information is collected about the site and individual users, and then pre-populated on the required registration forms. Once you have completed online registration, you will simply need to print, sign and submit the necessary forms as described on each form's instructional coversheet. Prior to completing online registration, please review our Registration Overview
, which outlines some helpful hints.
To complete Group Registration, select Group Registration below and see the Group Registration Guide for step-by-step instructions.
To complete Site Registration, select Site Registration below and see the Site Registration Guide for step-by-step instructions.
If your site’s Access Administrator (AA) has already completed the Site Registration and has identified you as a MIIS User or additional AA, you must register as an individual user to gain access the system. To complete MIIS User Registration, select the MIIS User Registration below and see the User Registration Guide for step-by-step instructions.
