Senate Bill 1949, known as the "mRNA Bioweapons Prohibition Act," seeks to amend Tennessee law by designating mRNA injections and products as weapons of mass destruction. The bill prohibits the possession or distribution of these products within the state. It defines "mRNA injections and products" to include COVID-19 injections that utilize modified messenger RNA, any human gene therapy products for infectious diseases, and nanotechnology that alters genes. However, it clarifies that naturally occurring messenger RNA is not included in this definition.

The bill establishes criminal offenses for individuals who knowingly manufacture, acquire, or possess mRNA injections and products, as well as for state or local government officials who fail to enforce these prohibitions after being presented with evidence of violations. Violations are punishable under existing law, and residents may seek various forms of legal relief against the state or officials for lack of enforcement. The act is set to take effect on July 1, 2026, and will apply to conduct occurring on or after that date.
