HB 364 Montana House · 2025 Regular Session

Generally revise laws related to immunizations

HB 364 proposes to update laws concerning student immunizations and exemptions in K-12 schools. It would require school governing authorities to submit written reports on student immunization and exemption data to state and local health departments. These reports must only contain deidentified or aggregate information, ensuring student privacy. The Department of Public Health and Human Services would determine the specific form and schedule for these reports.

MODERATE
The bill was amended to restructure the reporting requirements for school immunization data, shifting from a general mandate to a specific list of four required metrics. Additionally, the enforcement section was significantly expanded to include detailed reporting on enrollment numbers and conditional enrollment status alongside vaccination data.
Scope change
The reporting scope was expanded to require specific data points on enrollment and conditional enrollment, rather than just aggregate exemption and vaccination counts.
REQUIREMENT

The reporting mandate was changed from a general requirement to include specific data points: total enrollment, students with vaccine exemptions, fully vaccinated students, and students with conditional enrollment.

A new deadline was added, requiring the annual written report to be submitted by December 1 of each year.

ENFORCEMENT

The enforcement section was expanded to explicitly detail the specific data categories that must be included in the report.
