Tim Friede, who intentionally exposed himself to snake venom for nearly two decades, is helping scientists develop a universal antivenom. His unique antibody response, built through repeated exposure, is being studied. Researchers identified two antibodies in his blood that neutralize venom from various snake species, offering a potential breakthrough in treating snakebites, which kill around 110,000 people annually. While early tests on mice show promise, human trials are years away, and the antivenom isn't effective against all snake types. Friede cautions against replicating his dangerous method.
