Researchers may have found the key to creating the ultimate snake antivenom, and all it took was someone getting bitten 200 times.

Tim Friede might be the world's most snakebit person—and his antibodies could hold the key to a truly universal snake antivenom.

Jacob Glanville, founder of San Francisco-based vaccine developer Centivax and lead author of the study, met Friede in 2017. Working with Peter Kwong , a Columbia University vaccine researcher, Glanville’s team isolated the antibodies and tested them in the mice.
