When Tim Friede, an American self-taught researcher, began injecting himself with diluted snake venom in the early 2000s, many dismissed him as reckless or delusional. But two decades and over 700 venom exposures later, Friede has not only survived — he may have paved the way for creating a universal antivenom, now pursued by U.S. biotech firm Centivax.
Friede’s blood, rich with broad-spectrum antibodies, is being studied as the foundation for a treatment that could neutralize venom from multiple snake species — something the world has never seen.
With India bearing the world’s highest snakebite mortality, the news has sparked curiosity and caution among those on the front lines. Indian snake catchers, doctors, and enthusiasts offer their reactions to Friede’s controversial journey — and what it could mean for India’s ongoing fight against venom.

“While a universal antivenom could revolutionize treatment, ensuring regional efficacy, improved venom studies, and standardised production is critical for success.”
“Current polyvalent antivenoms primarily target the ‘Big Four’ (cobra, krait, Russell’s viper, saw-scaled viper), leaving many species untreated. Hence, this could be a breakthrough.”
Aaron Fernandes, a Conservationist and Reptile Enthusiast in Goa, says,
“It’s unsafe to try this out of an experiment without medical backing. There have, however, been instances where people have injected themselves with venom over a few years, become immune to certain types of snake bites, and helped other people recover from snake bites. As rarely as this has been done, it is possible.”
“Snakes have only been researched in terms of surface level, still, a deeper understanding is something the country could use about anti-venom.”
Dr. Genelia Kasad, a Toxicologist from Mumbai, said,
“While it’s true that repeated exposure to small doses of venom can trigger the immune system to produce antibodies, this kind of self-experimentation is hazardous and medically unadvised. Yes, the individual may have developed some level of resistance, but this doesn’t make him immune to all snake venoms, nor does it mean this approach is safe or replicable for others.”
With the expert advice here, it becomes clear that Mr. Friedy either got very lucky with survival or had medical assistance every step of the way.
“India has almost half of the global deaths by snake bites every year,” according to a statistic pointed out by Mr. Aaron, and with that being said, the need for antivenoms becomes more and more pressing by the day.
