The Laura Dowling Experience Dr Andy Hogan on How the Immune System Shapes Your Health
🎧 Episode Description
This episode traces Dr Andy Hogan’s path into immunology, from a childhood curiosity to a career exploring how the immune system shapes our health. Growing up in a challenging environment, the Access Programme gave him a route into higher education - highlighting the impact of support and opportunity.
Alongside his story, Andy explains the immune system not just as a defence against illness, but as something deeply involved in everyday health. He explores how obesity, ageing, and chronic inflammation affect immune function, and how these links connect to conditions like diabetes, cancer, and infection.
There’s also reflection on COVID-19, vaccines, and the future of medicine - from why pandemics were expected to how immunity develops over time. It’s a conversation that blends scientific insight with real-world impact.
🔑 Key Points
A single opportunity can reshape a future
