How do personalized mRNA cancer vaccines target tumors?

Personalized mRNA cancer vaccines help our body fight cancer by giving it special clues to find and attack the tumor.

Imagine your body is like a detective team. When they get a clue, they know exactly who to look for. That’s what happens with these vaccines, they give the body a special clue, made from pieces of the tumor itself.

The vaccine uses something called mRNA. Think of it like a message that tells our body's soldiers (called immune cells) how to recognize the cancer cells. This message is made from bits of the tumor, so it’s like a picture of the enemy.

When the soldiers get this message, they learn what the enemy looks like and then go on a mission to find and destroy them in the body, just like how you might use a photo to spot your friend at school!

Each person's tumor is a bit different, like each kid has a unique fingerprint. So, the mRNA message is made specially for each person’s tumor, it’s like getting a custom-made detective clue that fits exactly what the body needs to win the fight against cancer.
