House Bill No. introduced by G. Kmetz and others seeks to prohibit the administration of gene-based vaccines for infectious diseases in the state of Montana. The bill defines "gene-based vaccine for infectious diseases" as those developed using mRNA technology, modified mRNA technology, self-amplifying mRNA technology, or DNA technology. It explicitly states that this definition does not include gene therapy products used to treat cancer or genetic disorders. Violators of this law would be guilty of a misdemeanor and subject to a $500 fine for each incident, with the appropriate licensure board reviewing the licenses of those who violate the law.

The bill emphasizes concerns regarding the safety and long-term effects of mRNA vaccines, citing potential adverse events, lack of informed consent, and the possibility of these vaccines integrating into the human genome. The legislation aims to address these concerns by prohibiting the administration of such vaccines and establishing penalties for non-compliance. Additionally, the bill includes a codification instruction indicating that the new section will be integrated into Title 45, chapter 5 of the Montana Code.
