Montana legislature prohibits gene-based vaccines in veterinary medicine

Montana's House Bill 418, introduced on February 12, 2025, aims to reshape the landscape of veterinary medicine in the state by imposing strict regulations on the use of gene-based vaccines for animals. The bill specifically prohibits licensed veterinarians from prescribing or dispensing various types of gene-based vaccines, including messenger ribonucleic acid (mRNA) and deoxyribonucleic acid (DNA) vaccines. Violators of this provision could face misdemeanor charges and fines of $500 for each incident, with collected fines directed to the animal health enterprise fund.

The bill seeks to address growing concerns among certain stakeholders regarding the safety and efficacy of gene-based vaccines in veterinary practices. Proponents argue that the legislation is necessary to protect animal health and ensure that veterinary practices adhere to traditional methods of treatment. However, the bill has sparked notable debates within the veterinary community and among animal health advocates, with some arguing that it could hinder advancements in veterinary medicine and limit options for disease prevention in animals.

In addition to the vaccine restrictions, House Bill 418 outlines various practices that constitute veterinary medicine, including diagnosing, prescribing treatments, and performing surgical operations on animals. It also clarifies that individuals may still conduct pregnancy testing on their own farm animals without falling under the bill's regulatory scope.

The implications of this bill are significant, as it could reshape veterinary practices across Montana, potentially limiting veterinarians' ability to utilize modern medical advancements. Experts warn that such restrictions may lead to increased disease prevalence among livestock and pets, ultimately impacting the agricultural economy and public health.

As the legislative process unfolds, stakeholders are closely monitoring the bill's progress, anticipating further discussions and possible amendments. The outcome of House Bill 418 could set a precedent for how veterinary medicine is practiced in Montana and beyond, highlighting the ongoing tension between traditional practices and modern medical innovations.
