Man Becomes Human Antivenom Factory After Letting Snakes Bite Him 200 Times

A Wisconsin man spent decades letting venomous snakes bite him—over 200 times—so he could help develop a universal snake antivenom. Scientists now say his blood is packed with antibodies, making him the ultimate human antivenom factory and a legend in weird science circles.
Centivax’s researchers are now tapping Tim Friede’s blood, which holds antibodies for 19 different snake venoms, as a blueprint for next-gen snakebite treatments. This viral science experiment could turn his decades-long obsession into a global breakthrough for antivenom research.
