Man who let snakes bite him 200 times spurs new antivenom hope
- Between 2000 and 2018, Tim Friede, a former truck mechanic from Wisconsin, was bitten by snakes over 200 times in his effort to develop immunity to their venom.
- Friede’s self-experimentation began after attending a class on milking snake venom and escalated to enduring deadly bites, motivated by mithridatism to build total immunity.
- In 2017, immunologist Jacob Glanville sought Friede’s blood to study its antibodies, which led to a Cell journal study showing they protect against multiple snake venoms.
- The new antivenom combines two antibodies from Friede’s blood with the drug varespladib, and researchers aim to develop a universal treatment covering many of the 600 venomous snake species.
- Friede stopped self-injecting venom in 2018 due to liability concerns but expressed pride in contributing to medical history and hopes to resume bites to aid research.
