Many human beings suffer from illnesses that force them to regularly inject themselves with various types of medication to stay healthy. American Tim Friede is also accustomed to this practice—but for very different reasons: for the past twenty years, he has been regularly injecting himself with… snake venom. A decidedly surprising approach, but one whose rather spectacular results could benefit all of humanity.
He has always been fascinated by these reptiles, especially the most dangerous ones, which he has been collecting since his adolescence. For him, the pythons and snakes generally found in private vivariums are of little interest. Instead of these snakes, which are relatively harmless to humans, he prefers cobras, mambas, vipers, taipans, and other highly venomous species, whose bites can be fatal.
A Matter of Life and Death
He quickly realized that he absolutely had to find a strategy to prevent a minor accident from one day turning into a real tragedy. So he decided to expose himself directly to these deadly substances. His goal: to force his body to develop a form of immunity, a bit like a vaccine. For almost twenty years, he has regularly administered substantial doses of venom—either by injecting it in diluted form, or by letting himself be bitten directly by one of his sharp-fanged charges.
These recurring attacks have had the effect of stimulating his immune system to a rather spectacular level. Over time, his body has learned to produce antibodies specialized in the response against these toxic agents, allowing him to survive bites that would likely have been fatal for any other human.
Originally, this curious practice had only one goal: to limit the risks associated with his favorite hobby. But what Friede didn't know at the time was that he had actually started a process that could ultimately save thousands of people around the world.
A Broad-Spectrum Antivenom
One day, he was contacted by Jacob Glanville, CEO of Centivax, a biotechnology company that develops antivenoms. Friede agreed to let the firm's engineers collect his supercharged antibodies—probably unique in the world—to develop an extremely effective antivenom serum.
And the results were nothing short of spectacular: after the first phase of testing, the researchers observed that this cocktail was capable of protecting mice against the venom of 19 snake species, all ranked among the most dangerous in the world.
This result is so exceptional because broad-spectrum antivenoms are rare and are generally limited to a maximum of ten species. The vast majority of known antivenoms only work against a specific species. However, the fact that Friede's immune system was regularly exposed to a large number of different species seems to have made her antibodies incredibly versatile, hence the versatility of this product.
Universal antivenom, the Holy Grail of toxinology
And the most exciting thing is that this may only be the beginning. According to Centivax, this preliminary work could well pave the way for the true Holy Grail of modern toxinology: a universal antivenom, capable of protecting a person against almost all of the world's most dangerous snakes.
This might seem almost trivial, given that snakes don't really pose a major threat in our countries. But such a product could be absolutely lifesaving in countries where these animals are a constant concern. We think, for example, of Australia, which is full of species, each more venomous than the last — including the famous desert taipan, which produces the most powerful venom ever recorded in a snake.
But this is even more true in India, Latin America, or sub-Saharan Africa, for example. In these regions, dangerous snakes are not only numerous—they are also notoriously aggressive and diverse. This results in a large number of potentially fatal bites that are often difficult to identify, further complicating treatment.
To top it all off, there are several socioeconomic factors that weigh heavily in the balance. Rural populations, for example, tend to work without shoes, and are therefore even more exposed to bites. This is far from ideal when the nearest hospitals are sometimes located several hours from the scene of the accident, and they may not even have access to the right antivenom due to a lack of resources.
As you can see, developing a virtually universal antivenom would be a huge step forward in addressing this public health problem, which claims the lives of more than 100,000 people each year. It will therefore be very interesting to follow the impact of this potentially revolutionary work, which emerged from a particularly unusual story.
