Does your immune system need boosting?

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken cut through the confusion around every aspect of our health and wellbeing.

What defines a well-functioning immune system, and why are some people seemingly "immune" to everything while others catch every cold? In this episode, Chris and Xand dive into the complex mechanics of immunology. They tackle the controversial trend of "immune boosting" and discuss the delicate balance between under-active and over-active responses.

To help unpick this, they're joined by Professor Dan Davis, Head of Life Sciences and Professor of Immunology at Imperial College London and author of Self-Defence - a myth-busting guide to immune health.
