How Does COVID vaccine and new variants Work?

The COVID vaccine helps your body learn how to fight off the virus, and new variants are like tricky versions of that same virus.

Imagine you're playing a game with a friend who keeps changing their moves, sometimes they hide behind a tree, sometimes they jump over it. That's like a variant: it’s still the same friend (the virus), but now they’re doing something different to try and trick you.

The vaccine is like giving your body a practice round before the real game starts. It shows your body what the virus looks like, so when the real virus comes in, or even a tricky variant, your body can quickly recognize it and fight it off, like a superhero with a secret weapon.

New variants are like when your friend learns new moves to make the game harder. Sometimes they’re easier to beat, sometimes harder. But your body keeps learning, just like you keep getting better at the game, so even if the virus changes, your vaccine still helps protect you!
