Scientists haven’t yet been able to produce snake venom antibodies in a lab, so, instead,
0:04
they rely on the immune systems of real live creatures to do it for them.
0:08
First, they find – and milk! – a venomous snake. Then, they inject that venom into an animal –
0:13
preferably something big, like a horse. But, because they don’t want to kill the horse, they
0:17
dose it with the venom little by little, and wait for it to naturally produce antibodies. Finally,
0:21
after collecting some of the horse’s blood and spinning it out, voila: antivenom. You can check
0:26
out this video to see the whole process in action, but the point is that making even a single vial of
0:30
antivenom is a really slow, expensive process – and snakebite victims often need several vials in
0:35
order to recover. Researchers are experimenting with ways to produce snake venom antibodies more
0:40
quickly and cheaply, and they’re even working on a universal antivenom. But for now, decreasing the
0:45
death toll of venomous snakes is going to require us to collectively agree that people shouldn’t
0:48
have to risk death just because they were born in a place with more snakes and less money. And
0:53
if we can do that, snakebite deaths could become a thing of the past. Or should we say, hissssstory.
