As calls to ban mRNA shots intensify worldwide, a growing number of U.S. states and communities are eyeing laws to prohibit or pause their use.

A bill introduced Tuesday in the Kentucky House of Representatives would ban until July 1, 2035, the administration of "any human gene therapy product for any infectious disease indication, regardless of whether the administration is termed an immunization, vaccine, or any other term."

Lawmakers in Idaho and Montana recently introduced similar bills. Legislative initiatives are in the planning stages or have been passed at the county level in at least four other states, including Iowa, South Carolina, Texas and Washington.

"A critical mass will soon be reached, forcing the federal government to follow suit," said epidemiologist Nicolas Hulscher of the McCullough Foundation.

Dr. Kat Lindley, president of the Global Health Project and director of the International Fellowship Program for the Independent Medical Alliance (IMA), said such initiatives are "important in sending the message" to public health agencies "that states recognize the damage mRNA shots have done to U.S. citizens."

Hulscher said the McCullough Foundation "will be actively engaged in legislative efforts to ban mRNA injections" in several states.

The state and local initiatives come as Rep. Thomas Massie (R-Ky.) called on the U.S. Food and Drug Administration (FDA) to "immediately revoke approval" of the COVID-19 vaccines, in a post Wednesday on X.

Montana bill cites contamination, lack of safety studies

Montana's House Bill 371 would ban mRNA vaccines entirely and classify their administration as a misdemeanor, citing the "enormous numbers of deaths, disabilities, and serious adverse events" the shots have caused.

The bill states that the vaccines "are contaminated with DNA, metallic particles, and other unknown nanoparticles" and may shed to others or "integrate into the human genome and be passed onto the next generation." It noted that no long-term safety studies of the mRNA COVID-19 vaccines have been completed.
