How do vaccines help babies fight infections? | How Vaccines Work?

Vaccines are like special training that helps babies get ready to fight off germs before they even meet them.

Imagine your baby’s body is like a toy box full of different toys, each toy is a fighter that can help protect the baby from a specific germ. But when a germ comes in, it's like a new toy that the baby hasn’t played with yet. The baby might not know how to fight it off and could get sick.

Vaccines are like giving your baby a preview of those germs, they show up as tiny, harmless versions so the baby’s body can practice fighting them. This way, when the real germ comes along later, the baby already knows what to do and can fight it off quickly, without getting too sick.

Think of it like learning how to catch a ball before the big game. When your baby gets vaccinated, their body is learning new tricks, just like they’re practicing for a fun game with friends.

Each vaccine teaches the body about one kind of germ, so over time, the baby becomes a super fighter who knows how to beat many different germs.
