How Antivenom is Made
Making antivenom is a fascinating process that often involves animals like horses. Here's how it generally works:
Getting the Venom
First, a small amount of venom is carefully collected from the animal, like a snake or spider. This process is called "milking" the venom. Scientists make sure to do this safely.
Injecting into an Animal
Next, tiny, harmless amounts of this venom are injected into a large animal, often a horse. This is done over a long period, like several months. The horse's body is very clever! It starts to build up a natural defense against the venom. This defense is called an "immunity."
Building Immunity
As the horse's body gets used to the venom, it produces special proteins called "antibodies." These antibodies are like tiny soldiers that fight off the venom. Over time, more and more venom can be injected into the horse without harming it, because its body has become very good at fighting it off.
Collecting the Antibodies
Once the horse has a strong immunity, a small amount of its blood is carefully drawn. From this blood, the scientists separate the part that contains the helpful antibodies. This part is then purified and turned into the antivenom medicine.
Ready for Use
Finally, this antivenom can be given to humans who have been bitten by the same type of venomous animal. The antibodies in the antivenom quickly go to work, neutralizing the venom in the person's body and helping them recover.
Types of Antivenom
Antivenoms are made for many different types of venomous creatures around the world.
Spider Antivenoms
There are specific antivenoms for dangerous spiders. For example, in Australia, there is an antivenom for the very dangerous funnel-web spiders. These spiders have powerful venom.
Another common antivenom is for widow spiders, like the black widow spider. These spiders are found in many parts of the world. Their bites can be very painful and cause serious health problems, but antivenom can help.
Antivenoms are a great example of how science and nature can work together to create life-saving medicines.
