Story Synopsis

Inside your body, there’s a careful team that works every day, even when you’re asleep. This story introduces the immune system as a friendly “internal army.” Miluna explains that germs are tiny living things that can make us sick. When they try to enter, your body has first lines of defense—like skin, tears, and mucus—that act like soft shields. If germs slip past, special cells notice them, send signals, and help the body fight back. Some cells “remember” what they’ve seen before, which is why vaccines and past illnesses can help protect you later. The story stays gentle and empowering: your body is not fragile. It’s learning, practicing, and taking care of you—quietly, kindly, and steadily.

In One Glance

The immune system protects the body from germs. Barriers like skin and tears help block invaders. If germs get inside, immune cells recognize them and coordinate a response to fight them. Afterward, some cells keep a memory of the germ, so the body can respond faster next time. This is part of how vaccines work. The story explains these ideas with calm language that helps children feel safe and curious about how their bodies care for them.
