Man Survives 200 Snakebites for Universal Antivenom

Tim Friede, a 58-year-old window cleaner from Wisconsin, has subjected himself to over 200 intentional snakebites in a remarkable effort to help develop a universal antivenom. His nearly two-decade-long, painful journey, which nearly cost him his life and limbs, has yielded antibodies that scientists believe could combat the growing global threat of snakebites.

This initiative is particularly urgent as climate change is projected to increase encounters between humans and venomous snakes, leading to a potential rise in the estimated 138,000 annual deaths and 400,000 disfigurements. Friede's replicated antibodies have shown promise in neutralizing toxins from a significant portion of venomous snake species.

A company named Centivax is working with Friede to isolate these antibodies for antivenom production. A trial for this new antivenom is slated to begin with pets in Australia later this year, before any potential human use.

Friede's dangerous experiment, which began as a personal puzzle to understand immunity, involved keeping about 60 snakes in his home. Despite near-fatal experiences, including a coma in 2001, he persisted with his self-experimentation. He is motivated by the plight of vulnerable populations disproportionately affected by snakebites. The development of this antivenom offers hope for a more accessible treatment, especially as global aid budgets face cuts.
