Meet the man who survived 200+ snakebites, now scientists are using his blood to save lives

A Wisconsin-based man has turned personal risk into a potential medical breakthrough. Tim Friede, a snake enthusiast, deliberately exposed himself to more than 200 snakebites and hundreds of controlled venom injections over nearly two decades. His unusual immunity is now helping scientists develop a new kind of antivenom that could save thousands of lives worldwide, including in India, where snakebites claim thousands of victims annually.

From Hobby to Scientific Breakthrough

Friede’s fascination with snakes went beyond collecting or observing them. He meticulously documented every bite, tracking his health and the effects of venom on his body. Over time, his immune system developed antibodies capable of neutralizing neurotoxins, the molecules responsible for shutting down breathing, across a variety of deadly snakes, including cobras, mambas, and kraits.

A Safer, Faster Antivenom in the Making

Using Friede’s antibodies as a blueprint, scientists developed an experimental antivenom that combines lab-made human antibodies with a molecule called varespladib, which inhibits venom enzymes. Early studies on mice show the therapy can protect against lethal doses from multiple snake species, offering hope for a single treatment capable of working across many regions and species.

Experts emphasize that Friede’s personal approach was highly risky and should never be repeated. However, his immunity has provided a blueprint for creating safer, faster, and more universal antivenoms, potentially reducing the time and complexity of treating snakebites in rural areas.

Currently, the antivenom targets elapid neurotoxins. Scientists are working to expand coverage to vipers and other snakes, scale up production, ensure heat-stable formulations, and make the therapy affordable. These steps are crucial for countries like India, where many snakebite victims live far from advanced hospitals and timely treatment can mean the difference between life and death.
