Immunologist Jenna Macciochi takes a sceptical look at the long history of people’s attempts to boost immunity. She will reveal that immunity is not so much a “thing” as it is a complex system and leave us with some science-based guidance to what we can do to give our bodies the best shot at staying healthy. As we continue to battle the global pandemic, interest in the immune system is at an all-time high. Dr. Jenna Macciochi is a Senior Lecturer in Immunology at the Sussex University School of Life Sciences. As a gifted science communicator, Jenna has pursued a mission to spread the latest science-backed information on how to improve our immunity as well as to debunk myths on the topic. Her first book, Immunity: the Science of Staying Well, was published in 2020 by Harper Collins. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
