Tim Friede’s Daring Journey Results in a Universal Antivenom That Could Save Thousands
In an extraordinary tale of human endurance and scientific innovation, Tim Friede, a former truck mechanic from Wisconsin, has helped scientists develop what is being hailed as the most broadly effective antivenom to date. For nearly two decades, Friede deliberately injected himself with venom from some of the world’s deadliest snakes, including black mambas, cobras, taipans, and kraits, enduring over 200 bites and 850 injections. His blood has now become the key to a universal antivenom that could transform snakebite treatment worldwide.
A Dangerous Obsession Turned Lifesaving Mission
Friede’s journey began in 2000 with a fascination for venomous creatures, initially extracting venom from scorpions and spiders. Driven by curiosity and a desire to protect himself while handling snakes, he started self-administering diluted snake venom, gradually increasing the doses. Over 18 years, he exposed himself to venom from 16 snake species, surviving close calls, including a four-day coma induced by two cobra bites. His risky endeavor, which he documented on platforms like YouTube, was not without controversy, but it caught the attention of scientists at Centivax, a U.S.-based biotechnology company.

Breakthrough in Antivenom Development
In 2017, immunologist Jacob Glanville, CEO of Centivax, recognized the potential of Friede’s unique immune history. By analyzing Friede’s blood, researchers identified two potent antibodies, LNX-D09 and SNX-B03, which neutralize neurotoxins found in the venom of elapid snakes, a family that includes cobras, mambas, and taipans. These antibodies were combined with varespladib, a small-molecule drug that inhibits venom enzymes, to create a three-part antivenom cocktail.
Tested on mice, this antivenom provided full protection against lethal venom doses from 13 of 19 snake species and partial protection (20% to 40%) for the remaining six. The species tested included some of the world’s deadliest snakes, such as Australia’s eastern brown snake and inland taipan. According to Glanville, the results are “unparalleled” in antivenom research, offering hope for a universal antivenom that could treat bites from multiple snake species without the need for species-specific treatments.
Revolutionizing Snakebite Treatment
Snakebites are a global health crisis, killing up to 140,000 people annually and leaving hundreds of thousands with permanent disabilities, particularly in rural areas of Africa, Asia, and Latin America. Current antivenoms, produced by injecting venom into animals like horses and harvesting their antibodies, are often limited by the need to match the venom to a specific snake species, which can vary by region. Friede’s antibodies, derived from human blood, could reduce side effects compared to animal-based antivenoms and simplify treatment protocols.
“Tim’s antibodies are really quite extraordinary—he taught his immune system to get this very broad recognition,” said Professor Peter Kwong from Columbia University’s Vagelos College of Physicians and Surgeons, a co-author of the study published in the journal Cell. The researchers aim to enhance the formula by adding a fourth antibody to provide full protection against all elapid venoms and are planning trials in dogs at Australian veterinary clinics.

Ethical Concerns and Future Prospects
While Friede’s contribution is groundbreaking, experts like Professor Nick Casewell from the Liverpool School of Tropical Medicine caution that more research is needed before the antivenom can be used in humans. Glanville has also emphasized the dangers of Friede’s methods, stating, “We strongly discourage anyone from trying to do what Tim did. Snake venom is dangerous.” Friede himself stopped his self-immunization in 2018 after several near-death experiences and now works with Centivax to further antivenom research.
The ultimate goal is a single antivenom that can treat bites from all venomous snakes or separate injections for elapids and vipers. Such a development could save countless lives and reduce the burden of snakebite-related disabilities in vulnerable communities.
A Legacy of Courage and Impact
For Friede, the journey has been deeply personal. “It just became a lifestyle, and I kept pushing as hard as I could—for the people who are 8,000 miles away who die from snakebite,” he told the BBC. His perseverance has not only challenged conventional approaches to antivenom production but also highlighted the potential of human-derived antibodies in medical science.
As researchers move toward clinical trials, Friede’s 18-year experiment stands as a testament to the power of unconventional paths in driving scientific progress. The world may soon have a lifesaving snakebite treatment thanks to one man’s daring vision.
