Cardiologist Dr. Peter McCullough challenges official COVID-19 narratives, claiming vaccines caused 500,000+ deaths via underreported adverse events, presenting evidence of spike protein persistence in organs and proposing detoxification protocols using natural compounds—claims widely disputed by medical establishments. McCullough asserts the McCullough Protocol for early COVID treatment was suppressed despite allegedly preventing hospitalization and death, while alternative treatments like hydroxychloroquine and ivermectin faced coordinated discrediting campaigns. He claims 19,609 deaths reported to VAERS represent a 30-fold underreporting factor, suggesting true vaccine-related mortality reaches 500,000-600,000 deaths in the U.S. alone.
