How do vaccines work to protect our bodies from disease?

Vaccines are like training your body to fight off bad guys before they attack.

Imagine your body is a superhero team, and germs are sneaky villains trying to take over your town. Vaccines give your superheroes a little peek at what the villains look like so they can get ready for the real battle.

When you get a vaccine, it gives your body a tiny piece of the germ, kind of like a photo of the villain. Your body sees this tiny piece and goes, "Oh, I know who this is!" It then makes special fighters called antibodies to remember how to beat that germ.

Next time the real germ comes in, like when you get sick, your antibodies are already ready. They jump into action and stop the germ from making you feel terrible.

It’s like when you practice for a big game, you know what to expect, so you can win faster!
