How COVID-19 mRNA Vaccines Work?

The mRNA vaccine helps your body learn how to fight COVID-19, like teaching a friend how to beat a game.

Imagine you have a secret message that tells your body how to make a special tool to catch the virus. The mRNA vaccine is like sending that secret message into your body through a tiny door, your skin!

Your body has little helpers called cells, and they’re like musicians who can learn new songs. When the mRNA vaccine enters, it gives these cells a sheet of music, instructions on how to make a special tool called an antibody.

Once your cells start making those antibodies, they become ready for battle. If you ever meet the virus again, your body can quickly use those tools to stop it from causing sickness, just like knowing the words to a song helps you sing it faster.

The message in the mRNA vaccine is temporary, kind of like how a drawing on paper fades away after a while. But the antibodies your body makes stay with you, helping you fight off the virus if you meet it again later!
