SB 1949, the "mRNA Bioweapons Prohibition Act," prohibits the manufacture, possession, or distribution of modified mRNA products (including certain vaccines and gene therapies) in Tennessee, classifying violations as Class B felonies - equivalent to weapons of mass destruction offenses. It defines prohibited products as synthetic mRNA with specific genetic modifications (e.g., N-methyl-pseudouridine substitutions) used in medical treatments, excluding naturally occurring mRNA. The bill requires state and local officials to investigate violations and allows residents to sue for enforcement failures. It exempts naturally occurring mRNA and takes effect July 1, 2026.
