Dr. Andrew Kaufman regarding polio.

Everything you’ve been told about polio is a lie.
From what causes it to how it spreads, the entire narrative was engineered to sell one thing — vaccines.
When you look at the original experiments, the story falls apart fast. Researchers tried to prove polio was contagious by feeding spinal fluid from a child who died of “polio” to healthy monkeys. Nothing happened. No paralysis. No sickness. Nothing.
So they tried again, this time injecting the spinal fluid under the skin. Still nothing.
Finally, they injected the fluid directly into the brains of the monkeys, and only then did they see injury. But what they created wasn’t polio. And that’s what they used as proof of a contagious virus.
That faulty science became the foundation for one of the biggest medical myths in history, that polio was infectious and could only be stopped with a vaccine.
In reality, the rise of paralysis lined up perfectly with the rise of industrial toxins like pesticides, arsenic, lead, and DDT. The environment was poisoned, and people were getting sick. But instead of addressing the toxins, the medical system built an empire around a false cause and a profitable solution.
This is how narratives are built, not on truth, but on experiments that serve an agenda.
