How do mRNA vaccines work to protect us from viruses?

An mRNA vaccine is like giving your body a map so it can build defenses against a virus.

Imagine you're playing hide and seek, and someone tells you where to look for your friend, that’s like an mRNA vaccine. It gives your body instructions on how to find and fight the virus.

When you get an mRNA vaccine, it sends a message into your body. This message is like a blueprint that tells your cells: “Make a copy of this protein, it’s part of the virus!”

Your body reads the blueprint and starts making these proteins. Then, your immune system sees them and goes on alert, thinking, “I’ve seen this before!” It gets ready to fight off the real virus if you ever meet it.

Once your body has practiced fighting the virus with these practice proteins, it remembers how to do it faster next time. So when you actually get infected by the virus, your immune system is already in gear, and that’s how you stay healthy!

It's like learning your multiplication tables before a math test, you're prepared!
