How do vaccines work? - Kelwalin Dhanasarnsombut?

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

Imagine you're playing hide-and-seek with a friend who always runs fast. You want to get better at catching them, so you practice running every day. That way, when the real game starts, you're ready.

That’s how vaccines work, they help your body practice fighting germs, so it can be strong and ready for the real battle.

When you get a vaccine, you’re given a weaker version of a germ. It's like getting a little push from a slow friend who’s not very good at hiding, easy to catch!

Your body notices this weak germ and starts working on it, making special soldiers called antibodies. These soldiers remember how to fight that germ.

Next time the real germ comes to attack you, your body says, “Hey, I’ve seen you before!” The soldiers jump in and stop the germ from making you sick, just like how you’d catch your fast friend after practicing.

So vaccines are like secret training sessions that help your body stay strong and ready!
