Man Let Deadly Snakes Bite Him More Than 200 Times, Now Scientists Say His Blood Could Revolutionize Antivenom

A self-taught truck mechanic who spent nearly two decades allowing some of the world’s deadliest snakes to bite him may have helped scientists achieve a medical breakthrough once thought impossible.

Tim Friede, an American snake enthusiast, intentionally exposed himself to venom from cobras, black mambas, taipans, and rattlesnakes over an astonishing 18-year period in a bizarre effort to build immunity.

According to reports, Friede endured 202 snake bites and injected himself with venom 856 separate times.

At one point, he reportedly suffered two cobra bites within a single hour and slipped into a coma.

Many experts viewed his experiments as reckless and extraordinarily dangerous.

But years later, scientists discovered something remarkable inside his blood.

In 2025, researchers reportedly isolated powerful antibodies from Friede’s immune system and used them to help create what may become the world’s first broad-spectrum antivenom capable of protecting against multiple deadly snake species at once.

The stunning development has drawn worldwide attention after researchers at biotechnology company Centivax combined Friede’s antibodies with the drug varespladib.

According to findings published in the journal Cell and covered by outlets including Nature and NPR, the treatment successfully protected mice against venom from 19 deadly snake species, including cobras and mambas.

That is something scientists have struggled to achieve for decades.

Traditional antivenoms are usually designed to treat bites from only one species or a small group of related snakes, forcing hospitals in many parts of the world to stock multiple different treatments.

Snakebite remains a major global health crisis, killing tens of thousands of people every year, particularly in rural regions across Africa and Asia.

The viral video circulating online shows Friede calmly handling a large venomous snake inside a room lined with enclosures before allowing the reptile to bite his arm.

The footage has left many viewers stunned that anyone would willingly expose themselves to such extreme danger.

Despite the apparent success of the research, experts continue to warn that attempting anything similar would almost certainly be fatal for most people.

Scientists say Friede’s case is highly unusual and involved years of gradual exposure under self-directed conditions.

Still, the former mechanic’s extraordinary and dangerous obsession may now help pave the way for a universal snakebite treatment capable of saving countless lives around the world.
