Between 2000 and 2018, former Wisconsin mechanic Tim Friede endured over 200 venomous snakebites and self-administered 650-plus diluted venom injections to build tolerance through mithridatism. Despite nearly dying early in his self-experimentation—including a four-day coma following back-to-back cobra bites—his hyper-immunity successfully developed over nearly two decades.
A study published in Cell revealed that a synthetic antibody cocktail derived from Friede's blood, paired with an anti-inflammatory compound, fully protected test mice against venom from 13 deadly snake species and offered partial protection against six others.
Researchers believe Friede's uniquely evolved antibodies could form the foundation for the world's first universal antivenom, potentially saving thousands of the estimated 138,000 global snakebite victims annually. Now serving as Director of Herpetology at Centivax, Friede's controversial path is heavily discouraged by medical professionals, who warn that self-immunization is extremely dangerous and should never be attempted.
