Minnesota 2025-2026 Regular Session

Minnesota House Bill HF3239

Introduced
4/24/25  

Caption

Use of an exemption to immunization due to conscientiously held beliefs for immunization against measles, mumps, and rubella prohibited.

Summary

HF3239 narrows Minnesota’s school and child care immunization exemption rules by ending the use of the “conscientiously held beliefs” exemption for measles, mumps, and rubella (MMR). Under current law, parents or guardians may submit a notarized statement claiming a conscientious-belief exemption for required immunizations; this bill would preserve that exemption for other vaccines, but not for MMR beginning August 1, 2026. After that date, children and students who previously relied on the conscientious-belief exemption for MMR would need to provide proof of MMR vaccination or qualify for a medical exemption. The bill applies to children enrolling or remaining enrolled in child care facilities, certified license-exempt child care centers, preschools, prekindergarten programs, and elementary or secondary schools. It also updates the statute’s definitions section to incorporate the new MMR-specific rule. In effect, the bill creates a targeted vaccine requirement for MMR while leaving other existing immunization exemptions in place for the rest of the statute.

Impact

HF3239 amends Minnesota Statutes section 121A.15 to remove the conscientious-belief exemption for MMR immunization in child care and school settings, effective August 1, 2026. It would require affected families to either document MMR vaccination or obtain a medical exemption, and it would apply to public, nonpublic, home school, and child care settings covered by the statute. The bill does not eliminate all nonmedical exemptions statewide; it specifically limits the exemption only for measles, mumps, and rubella.

Sentiment

The bill’s caption and structure suggest a public-health-oriented approach focused on increasing MMR vaccination coverage, and the available context shows it was introduced by multiple House authors and referred to the Health Finance and Policy Committee. Because there are no committee transcripts or recorded votes provided, there is no direct evidence here of debate or opposition in the legislative record supplied. Overall, the bill appears to reflect support for tighter immunization requirements rather than a broad overhaul of Minnesota’s exemption framework.

Contention

The main point of contention is likely the elimination of the conscientious-belief exemption for MMR, which affects parents and guardians who object to vaccination on religious or personal grounds. Supporters would likely emphasize disease prevention and school/child care outbreak control, while opponents may argue the bill restricts parental choice and religious or philosophical freedom. The bill is narrowly tailored, however, because it preserves medical exemptions and leaves conscientious-belief exemptions available for other immunizations, which may reduce but not eliminate controversy.

Cover Outstanding Vulnerable Expansion-eligible Residents Now Act or the COVER Now Act This bill establishes a demonstration program to allow local governments to provide health benefits to the Medicaid expansion population in states that have not expanded Medicaid. Under the program, local governments may provide coverage for individuals who are newly eligible for Medicaid under the Patient Protection and Affordable Care Act (i.e., the Medicaid expansion population) for a maximum of 10 years, or until their respective states expand Medicaid. The bill provides a 100% federal matching rate for the first three years of program participation. The bill prohibits states from taking certain actions against participating localities, such as withholding funding, increasing taxes, or restricting provider participation. States that violate these requirements are subject to certain funding penalties.
