This episode traces Dr Andy Hoganβs 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.
Thereβs also reflection on COVID-19, vaccines, and the future of medicine - from why pandemics were expected to how immunity develops over time. Itβs a conversation that blends scientific insight with real-world impact.
A single opportunity can reshape a future
The Access Programme gave Andy a pathway into higher education.
A childhood moment led to a scientific career
Early curiosity about genetics sparked a lifelong interest in biology.
The immune system shapes everyday health
It regulates metabolism, tissue health, and overall balance - not just infection.
Obesity and immune ageing are linked
Obesity can accelerate immune decline and affect disease response.
COVID-19 exposed immune vulnerabilities
The pandemic showed how differently populations respond to new threats.
Medical research is opening new possibilities
Immunology is unlocking new treatments for complex diseases.
Vaccines protect communities, not just individuals
They play a key role in protecting the most vulnerable.
