HB 1584 New Hampshire House · 2026 Regular Session

directing the department of health and human services to provide notice of medical and religious exemptions from immunization requirements and relative to notice of drug pricing options.

HB 1584 requires New Hampshire's Department of Health and Human Services to prominently display notices about medical and religious immunization exemptions on all vaccination-related materials, such as websites, brochures, or social media posts. It specifies that the notice must appear as visibly as main content - like a headline - and not just in footnotes. The bill also allows parents to use any written statement (not a specific form) to claim religious exemptions for their children's vaccinations. Additionally, the department must submit an annual report to the legislature detailing all promotional materials, compliance with the notice requirement, and any penalties assessed for noncompliance. This bill directly affects the Department of Health, schools, and healthcare providers distributing immunization information.

What changed between versions

Version adopted by both bodies CHAPTERED FINAL VERSION · 4 edits
MODERATE
The changes between these two versions are entirely procedural and formatting-related, reflecting the standard transition from a bill adopted by both legislative bodies to its final chaptered form after gubernatorial approval. The bill was assigned Chapter 328, section numbers were updated to include the chapter prefix (e.g., 1 became 328:1), the fiscal note was removed, and an approval date of July 15, 2026 with specific effective dates was added. No substantive policy language was changed.
TECHNICAL

Section numbers were updated to include the chapter number prefix: Section 1 became 328:1, Section 2 became 328:2, and Section 3 became 328:3.

The fiscal note section, which provided estimated state budget impact and methodology for cost analysis, was removed from the final version as is standard when a bill becomes law.

Line wrapping and formatting were adjusted throughout to accommodate the new chapter number prefix in section headings and to conform to final publication layout.

TIMELINE

An approval date of July 15, 2026 was added, along with explicit effective dates: Section 1 effective October 13, 2026 (90 days after passage) and the remainder effective January 1, 2027.
