Why is snake venom required to make anti-venom?
gpt
Anti-venom is antibodies that the immune system has produced in response to a foreign protein. In order to produce those antibodies, an animal is injected with the protein, and the antibodies produced by the animal are extracted and used for antivenom. So, you have to use the venom to train the animal's immune system to create the antivenom.
