I want to know how snake venom in the antidote makes sense? – Raagini, 10, New York

One of my roommates is a corn snake named Buddy. He’s not venomous. But he’s a very private individual and really likes his space.

Buddy and I talked about your question with my friend Blair Perry. He’s a biologist at Washington State University. He’s an expert on snakes and venom.

Perry told me antivenom doesn’t contain actual snake venom. It’s made with antibodies to snake venom.

Antibodies are proteins. They’re part of your immune system. They travel in your blood to fight germs or dangerous molecules—like those in venom—that could hurt you. Sometimes we get vaccines to boost our antibodies so they’re ready when something harmful shows up.
