RFK Jr. Calls for a World Prohibition on Mercury in Vaccines

Permitting mercury in vaccines while calling it dangerous in batteries and makeup is a ‘double standard,’ he said.

No ifs, ands or buts: All countries should eradicate mercury from vaccines following the standard set by the United States, according to Health Secretary Robert F. Kennedy Jr.

“The Minamata Convention was born from a shared moral conviction that no human being should suffer from exposure to mercury,” Kennedy said, during a Nov. 3 meeting in a video address to the Minamata Convention on Mercury in Geneva, Switzerland.

“Article 4 of the Convention calls on parties to cut mercury use by phasing out listed mercury-added products. But in 2010, as the treaty took shape, negotiators made a major exception. Thimerosal-containing vaccines were carved out in the regulation,” Kennedy said, referring to the mercury-based preservative used to prevent microbial growth in vaccines.

The treaty, according to The Epoch Times, which began to phase out mercury in cosmetics and lamps, chose to permit the substance to be used in products that are injected into vulnerable people—babies and pregnant women, the health secretary said.

“We have to ask: why? Why do we hold a double standard for mercury? Why do we call it dangerous in batteries, in over-the-counter medications, and makeup, but acceptable in vaccines and dental fillings?” Kennedy Jr. asked.

A key issue, Kennedy said, is that thimerosal has never gone through a proper safety testing in human beings. He added that hundreds of studies have classified the substance as a strong neurotoxin, carcinogen, endocrine disruptor, and mutagen.

“Thimerosal’s own label requires it to be treated as a hazardous material and warns against ingestion. There is not a single study that proves it safe,” he said. “That’s why in July of this year, the United States closed the final chapter on the use of thimerosal as a vaccine preservative, something that should have happened years ago.”

According to a March 2024 safety data sheet on Thimerosal, the substance is “considered hazardous” under the 2012 Hazard Communication Standard from the Occupational Safety and Health Administration.
