The immune system is the intricate constellation of cells and molecules in our bodies that defends us against disease and on this special bonus episode of New Scientist Weekly we delve into the latest science on how the immune system works.

Why do some people never seem to get ill? What was the effect of covid lockdowns on our immune system? Is it really possible to boost your immune system through eating certain foods? Do you have a naturally strong or weak immune system? And how can we engineer the immune system to seek and destroy cancers that have evaded treatment?

Discussing these issues are New Scientist journalists Rowan Hooper, Helen Thomson, Penny Sarchet and Michael Le Page. These stories and much more are explored in a special edition of New Scientist magazine, also available to download on our app.
