Snake Season: What to Do if a Venomous Snake Bites You?

- Friede's practice of mithridatism aimed to achieve total immunity and escalated after he took a class on milking snakes for venom in childhood.
- Immunologist Jacob Glanville, who shifted focus to antivenoms in 2017, studied Friede's blood antibodies to develop a broader antivenom with a drug called varespladib.

- Friede stopped self-injecting venom in 2018 to reduce liability for Centivax but remains proud of contributing to medical history and hopes to resume exposure carefully in the future.
