Massachusetts law (M.G.L. c. 111, Section 24M) requires providers to report
immunization information to a computerized immunization registry known as the
Massachusetts Immunization Information System (MIIS). The MIIS stores immunization records for you and your healthcare provider and can help prevent outbreaks of disease like measles and the flu. All information in the MIIS is kept secure and confidential. The MIIS allows information to be shared with health care providers, school nurses, local boards of health, and state agencies concerned with immunization. You have the right to object to the sharing of your immunization information across providers in the MIIS.
For more information, please ask your healthcare provider, visit the MIIS website at
www.mass.gov/dph/miis or contact the Massachusetts Immunization Program MIIS Help Desk directly at 617-983-4335.
