Imagine your body as a fortress under constant siege. Every single day, thousands of different viruses, bacteria and other microbes attempt to invade.

Your immune system is the army defending this fortress—and it’s incredibly good at its job. Without it, you would not survive.

They discovered the body’s secret security guards: Special cells that constantly patrol your body, making sure your defence system doesn’t accidentally destroy you.
