HB 156 New Mexico House · 2026 Regular Session

REPEAL SPECIAL SESSION VACCINATION LAWS

HB 156 would repeal specific vaccination-related provisions from New Mexico's 2025 First Special Session laws (Laws 2025, 1st S.S., Ch. 5, §§ 8-13). These repealed sections would have otherwise taken effect on July 1, 2026, governing certain vaccination policies. The bill removes these provisions from state law, effectively eliminating the requirements they established. As of now, the bill has passed committee hearings but remains pending legislative action.

Expanded from a repeal-focused bill to a substantive immunization policy bill covering both children in educational settings and adults residing in the state.

REQUIREMENT

Changed from repealing Laws 2025 Chapter 5 Sections 8-13 to creating new Section 24-5-1 governing immunization rules.

Added requirements for immunizations for children attending licensed childcare, early childhood programs, and public/private schools.

Added new subsection B requiring rules for immunization recommendations for adults residing in the state.

Added language requiring the public health division to supervise and secure enforcement of the immunization program.
