Product description

The Massachusetts Immunization Information System (MIIS), a web-based system that keeps track of all immunizations that healthcare providers report having administered to children and adults in Massachusetts. The system was established in 2011 and is operated by the Massachusetts Department of Public Health (MDPH) according to state law (M.G.L c. 111, Section 24M; 105 CMR 222). Beginning Tuesday, December 7, 2021 Massachusetts residents or individuals who have received a vaccination in Massachusetts may access the MIIS Patient Portal – My Vax Records to access their MIIS immunization record at

Through the MIIS Patient Access Portal – My Vax Records users will be able to:

  1. Access their MIIS records if a record is available
  2. Print or download their full immunization history certificate.


You are eligible to submit a request to access an MIIS record:

  1. You have received at least one vaccine in the Commonwealth of Massachusetts.


The Massachusetts Department of Public Health will review your request and attempt to match the information provided to an existing record in the MIIS.

By submitting a request, you consent to the electronic storage and transmission of the requested information, including the requested vaccine record, via the MIIS Patient Access Portal – My Vax Records and acknowledge under all applicable legal penalties that the information you have provided is true and that you have the legal authority to access the MIIS record and the information in it. You understand that you may face legal penalties for intentionally attempting to access a vaccination record that you do not have authority to access.

Absence or Inaccuracy of Vaccination Record in MIIS. The MIIS was established in 2011 and contains only those immunization records that providers have reported. Therefore, the MIIS may not contain all immunizations for every person in the Commonwealth. Contact your healthcare provider to request that any missing vaccinations be sent to the MIIS.

If you are not able to locate your MIIS vaccination record in the MIIS Patient Access Portal – My Vax Records or there are inaccuracies on the record, an Electronic Immunization Record Amendment form may be submitted along with sufficient proof of your identity to MDPH. The Massachusetts Department of Public Health will then make reasonable efforts to identify the vaccination record within MIIS if there is one, or correct inaccuracies in an existing record. Or you may contact the health care provider that administered the vaccination and request the information is sent to the MIIS or updated as necessary.
