What are antibodies?

Antibodies are like tiny superheroes that help your body fight off germs.

Imagine you're playing catch with a friend, and suddenly a ball comes flying at you, you catch it! That’s kind of what antibodies do. When something bad, like a germ or virus, enters your body, your antibodies go to work, trying to catch those bad guys so they can’t make you sick.

How Antibodies Work

Think of antibodies as special gloves that fit perfectly on germs. Each antibody is shaped just right for one kind of germ, like how your hand fits perfectly in a glove. When the antibody finds its match, it grabs onto the germ and either stops it from doing damage or helps other parts of your body know to come help out.

Sometimes, after you've caught a germ once, your body remembers it. Then the next time that germ comes around, your antibodies are already ready, like having a special glove for every kind of ball you play with!
