The Massachusetts Department of Public Health (MDPH) keeps people healthy and communities strong. DPH promotes the health and well-being of all residents by ensuring access to high-quality public health and healthcare services, focusing on prevention and wellness, and health equity for all. The MDPH Immunization Division is committed to promoting the health of Massachusetts residents by reducing the burden of vaccine-preventable diseases. As part of this effort, in 2011 the MDPH Immunization Division launched the Massachusetts Immunization Information System (MIIS) As the state’s immunization information system, MIIS has played a critical role for the state and its residents during the COVID-19 pandemic.



The COVID-19 pandemic emphasized the need for consumers to be able to provide proof of immunization against COVID-19 to their medical providers, for travel, entry to local businesses, and more. Massachusetts sought a way to provide consumers access to their vaccination records in a secure and effective way. The Commonwealth was looking for something that could:

  • Handle large volumes of requests from the public at the same time, without the system crashing
  • Provide secure access while still remaining compliant with HIPAA and other regulations
  • Be user-friendly and straightforward for the public to use
  • Reduce the burden on MIIS staff to handle requests manually
  • Integrate with the existing MIIS Support record amendment requests from the public in instances where errors were found


The consumer access portal, called My Vax Records was built on SSG’s Casetivity platform and launched in January 2022. It connects directly with the MIIS to provide consumers secure access to their vaccine records.

My Vax Records presents a person’s complete immunization record to them, including COVID-19 vaccinations and vaccines provided across different locations. Additionally, consumers can access their dependents’ complete immunization records from the same application.

When using My Vax Records, consumers enter their demographic information and a mobile phone number or an email. The system queries the MIIS for a matching record and when their record is ready, they will receive a text message or email (based on what they initially entered) with a link to their record and a SMART health card. If there is an issue with their record, they can submit a record amendment request via a webpage built on Casetivity that alerts the MIIS team to fix errors.
