Go behind the scenes at our biggest day of the year – Discovery Day!

Every year, we open our doors to families so they can chat to our scientists and do fun hands-on activities. In this video, Dani tests out a game with Zoe and Sasha, two scientists who look at how your immune system helps to defend your body. Watch to see Dani learn about different immune cells.

What is your immune system?

Your immune system is your body's defence system. It helps protect you from injuries and fight off infections caused by germs that can make you sick. The immune system is made up of lots of different types of cells. These cells are tiny and adapted to do different jobs in your body. Some are super-fast, some are super-sticky and some are super-squishy. Working together with their combined superpowers, immune cells help keep you healthy.

Sometimes, immune cells don't work the way they are supposed to. By putting immune cells through lots of different tests, scientists like Zoe and Sasha can figure out what's going wrong and think of ways to fix them.
