The Tenpenny Files with James Grundvig

For more than twenty years, parents have been told there was nothing to see. The studies were done. The questions were answered. The science was settled. Meanwhile, autism rates continued to rise, families searched for answers, and physicians who challenged the narrative found themselves attacked by medical boards, government agencies, professional organizations, the media, and a public conditioned to believe the debate was over. Investigative journalist James Grundvig, whose own son regressed into autism after childhood vaccinations, has spent more than a decade examining one of the most controversial stories at the center of that fight.

Millions of families have lived with the consequences. Parents who trusted the system watched their children change and were told their concerns were anecdotal. Doctors who spoke out risked their careers, reputations, and livelihoods. The deeper the questions became, the harder institutions worked to convince the public that everything had already been investigated.

In Master Manipulator, Grundvig documented the rise of Danish researcher Poul Thorsen, the CDC-funded autism studies that helped shape public trust in vaccine safety, and the financial crimes that eventually led to a federal indictment. What many assumed was an old story has suddenly become very current because Thorsen has now been extradited to the United States.

Grundvig joins Dr. Sherri Tenpenny to examine the studies that influenced public policy, the allegations of fraud and scientific misconduct that followed, and the questions that refused to disappear. The conversation explores mercury, aluminum, autism rates, government accountability, and the institutions that helped defend a narrative long after concerns were raised.

This interview goes beyond the headlines and beyond the book. Master Manipulator contains years of additional documentation, investigative research, timelines, and source material that could not be fully explored in a single conversation. As legal proceedings move forward, one question hangs over the entire story: if the man at the center of this controversy is finally forced to answer questions under oath, what might the public learn about one of the most consequential public health debates of our time?
