We comply with the Massachusetts law (M.G.L. c. 111, Section 24M) which 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 healthcare 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 www.mass.gov/dph/miis or contact the Massachusetts Immunization Program directly at (617) 983-6800 or (888) 658-2850.
