Sharing Immunization Information

The Massachusetts Immunization Information System (MIIS) is a confidential, web-based system that collects vaccination records for people of all ages vaccinated in Massachusetts.

The MIIS is operated by the Immunization Division at the Massachusetts Department of Public Health and helps you, along with your healthcare providers, keep track of the shots that you have received.

Why is the MIIS Important?

The schedule of vaccines that you need to stay healthy and that are required for you becomes more complicated with every new vaccine introduced. Keeping all your shot records in one place helps to make sure that you receive the complete schedule of immunizations.

What information about me will be entered into the MIIS?

Boston University Student Health Services is mandated to report any immunizations we administer to the MIIS. Other information, including address, date of birth, sex, and the provider office location will also be included in the registry to be sure that your records are accurate and cannot be confused with another patient’s record. All the information in the MIIS is secure and confidential.

What if I do not want to share my immunization information?

The law requires that immunizations are reported to the Massachusetts Department of Public Health through the MIIS. There is no option to “opt-out” of the MIIS. Your records will only be available to those involved in your care, who have a reason to know about them. The MIIS enables Student Health Services to verify what shots you have received in the past from other providers. If you prefer that your immunization history not be viewed by new providers, you may object to sharing your immunization information.

If you object to data sharing, your immunization information will still be in the MIIS, but only the provider(s) who administered your vaccines and the Department of Public Health will be able to see it. To object to data sharing, you must complete the MIIS Objection (or Withdrawal of Objection) Form. If you change your mind, you can fill out the same form to have your immunization information shared in the MIIS.

Please note: you will need to keep track of your records in the event that you receive immunizations from other health care providers.
