Snake bites kill tens of thousands of people around the world each year. But we still use techniques invented in the late 19th century to make antivenom, and each bite needs to be treated with antivenom for that specific type of snake.

We hear from two scientists whose recent breakthroughs – and failures – could save many more lives and help achieve the holy grail: a universal antivenom. Featuring Stuart Ainsworth, senior lecturer at the University of Liverpool in the UK and Christoffer Vinther Sørensen, postdoctoral researcher at the Center for Antibody Technologies at the Technical University of Denmark.
