About Us
The Massachusetts Department of Public Health (MDPH) Immunization Division is committed to promoting the health of Massachusetts' citizens by reducing the burden of vaccine preventable diseases that affect residents of the Commonwealth. A part of this effort is the Massachusetts Immunization Information System (MIIS), a web-based immunization registry and vaccine management system. The MIIS is the official source of immunization information for Massachusetts. The goal of the MIIS is to consolidate patient immunization information to create secure, accurate and easily accessible immunization records to health care providers across the Commonwealth, who can then share them with patients and families. The MIIS also helps ensure vaccines administered in Massachusetts are based on the latest immunization recommendations.
The MIIS is designed to serve the needs of electronic health record (EHR) users through electronic data exchange and can also support the needs of non-EHR users through direct data entry. Please visit MIIS Information for Providers for an overview of MIIS features and more information about utilizing the MIIS.
MIIS Regulations
The Regulations (PDF) governing the MIIS have been approved by the Massachusetts Public Health Council and were effective as of January 2, 2015. Section 222.400 of the regulations states that all health care providers licensed in the Commonwealth who administer immunizations in Massachusetts to any person, whether or not that person is a resident of the Commonwealth, shall be in compliance with the regulations. All providers should be reporting to the MIIS as of June 2016.
By law (M.G.L. Chapter 111, Section 24M), the MIIS must be discussed by providers with each of their patients
before immunization data is first entered or transmitted to the
system. This should be done at the first immunization encounter after
the MIIS has been integrated into the practice. For information on
informing patients, please visit the MIIS Materials
page.
MIIS and Birth Hospitals
Information about immunizations given at birth are automatically sent
to the MIIS from the Registry of Vital Records and Statistics (RVRS).
Providers and institutions have a legal responsibility to inform
parents/guardians about the MIIS. Please review the official
notification sent to Birth Hospitals about their duty to inform
expecting parents about the MIIS. MIIS Birth Hospital Memo (PDF) | (RTF)
