The Massachusetts Medical Society (MMS) told the Joint Committee on Public Health that declines in immunization rates and rising vaccine hesitancy pose a public‑health threat, particularly for measles.

Hugh Taylor, president of the Medical Society and a family physician, said the CDC reports thousands of measles cases nationwide and that some New England neighbors have reported cases. “Massachusetts has not reported a case yet,” Taylor said, “but we are definitely at risk here.” He noted that herd immunity for measles requires about 95% coverage and that local pockets can fall far below that threshold.

The MMS urged the committee to remove all non‑medical exemptions from the school immunization law, citing evidence that states eliminating non‑medical exemptions have improved immunization rates. The society also emphasized the need for physicians and public‑health agencies to counter misinformation and for targeted outreach where local vaccination coverage is low.

Why it matters: The society warned that clusters of under‑vaccinated students could trigger outbreaks and that delays in care or misinformation heighten risk for vulnerable populations. Committee members asked about the quality and completeness of vaccination data and noted reporting limits in some communities.

What’s next: MMS said it stands ready to work with the committee on legislation to reduce non‑medical exemptions and to assist with provider and public outreach to rebuild vaccine confidence.
