Summary: An Act relative to routine childhood immunizations (HD 3775)

Overview

This proposed Massachusetts bill would expand transparency around school-based immunization data. It would require all kindergarten-through-12th grade (K–12) schools—public, private, and charter—to report immunization activity to the state and would obligate the state to publish aggregate data about immunizations and exemptions. The aim is to provide public visibility into vaccination compliance across schools and districts while preserving student privacy.

Key provisions

  • Annual reporting by all K–12 schools to the Department of Public Health (the department) of:

    • Total number of children who are successfully immunized in accordance with immunization requirements, and
    • Total number of children exempted from immunization requirements.
    • The department will designate the methodology for how this reporting is to occur.

  • Annual publication by the department of aggregate data:

    • Publicly available immunization and exemptions data for each school and school district.
    • Data publication is not required if disclosure would reveal personal information or violate privacy laws.
    • The department may publish data by geography (e.g., municipality, county) or use other reporting formats at its discretion.

Who is affected

  • All schools serving grades K–12 in Massachusetts (public, private, and charter).
  • Students and families (through the visibility of school-level immunization data).
  • Local school districts and the Department of Public Health.

Context and legal framework

  • The bill would amend Section 15 of Chapter 76 of the General Laws (as it appeared in the 2020 Official Edition) by replacing the current third paragraph with two new paragraphs as described above.
  • The reporting and publication requirements are framed as aggregate data to protect individual privacy, aligning with privacy protections in state law (e.g., potential alignment with Chapter 93H privacy safeguards).

Timeline and implementation

  • Status: Proposed bill introduced in 2025. The exact effective date and implementation timetable are not specified in the text provided.
  • If enacted, the department would implement the reporting methodology and begin annual reporting and publication going forward.

Background note

  • A similar measure related to routine childhood immunization reporting has been filed in a prior session (House No. 604, 2023–2024), indicating ongoing legislative interest in transparency around school immunization data.
