Allergies, the Immune System and Parasites

09 July 2006
Presented by Chris Smith, Kat Arney.

In honour of the annual hoards of bleary-eyed hayfever sufferers, we are joined in the studio by Professor Carrock Sewell from the University of Lincoln, who describes how the immune system works, what causes allergic reactions and how we might be able to cure them, and Dr Mark Booth from Cambridge University discusses parasites, how they suppress and evade the immune system and how the Matangini Project attempts to provide parasite-free water in Africa. Sticking with the African continent, Derek Thorne travels to Tanzania to learn how to make ugali in this week's Kitchen Science.
