On April 24th Professor Sally Bloomfield gave a teleclass outlining the latest thinking on the, so called “Hygiene Hypothesis”. The presentation also explored the question “Can we have it both ways?” i.e how can we develop lifestyles, medical and public health strategies which reconnect us with the natural animal and environmental microbiota, whilst at the same time protecting against infectious diseases?
