May and Tim Hindmarsh sit down with activist and advocate Sofia Karstens to uncover the story of Dr. Bernice Eddy, a pioneering NIH scientist who warned about flaws in the original polio vaccine—only to be silenced.

Show Notes
This powerful conversation dives deep into the life and legacy of Dr. Bernice Eddy, a courageous scientist who uncovered that early batches of the polio vaccine contained live poliovirus—sparking what became known as the Cutter Incident, one of the worst pharmaceutical disasters in U.S. history.
Guest Sofia Karstens joins the Hindmarshes to connect Eddy’s story to today’s debates over medical transparency and accountability. The discussion traces how Eddy’s findings led to discoveries about SV40, a cancer-causing monkey virus, and how institutional pressure buried crucial truths.
The trio also examines the broader implications—how rushed medical products, lack of testing, and censorship continue to threaten public trust. Sofia brings her activist insight to highlight the role of whistleblowers, the persistence of corruption in regulatory systems, and what ordinary citizens can do at the local and grassroots level to reclaim their power.
It’s a riveting exploration of truth, science, courage, and the cost of speaking out—a timely reminder that protecting health freedom begins with asking hard questions.
