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, while explicitly excluding gene therapy products used to treat cancer or genetic disorders. Violators of this prohibition would be guilty of a misdemeanor and subject to a $500 fine for each incident. Additionally, the appropriate licensure board within the Montana Department of Labor and Industry would review the licenses of individuals who violate this 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 proposed legislation aims to codify these provisions as part of Title 45, chapter 5 of Montana law.
