Health Misinformation: UNPACKED

 Why do we fall for false or misleading information about our health? And in a world flooded with viral claims and conspiracy theories, how can we fight back? On September 15th 2025, the London School of Hygiene & Tropical Medicine brought together world-leading experts to tackle one of the most urgent threats to public health: misinformation. In this special episode, host Karl Byrne takes you inside the event to unpack the key takeaways. You'll hear from behavioural scientists on the psychology of "pre-bunking" and why our emotions make us vulnerable; journalists on the practical challenges of verifying news in a 24/7 cycle; and global health experts on how the fight looks different from West Africa to the UK. Featuring insights from Professor Sir Chris Whitty (Chief Medical Officer for England), Professor Sander van der Linden (University of Cambridge), LSHTM researchers, experts from BBC Media Action, PA Media, and international organisations. This episode explores the timeless techniques behind the misinformation machine, how we can effectively fight it and asks what it will take to rebuild trust. This isn't just a discussion about fake news- it's about finding clarity in the chaos.Find out more about the network to fight health misinformation in the UK and how you can help.

This summer, chikungunya has been making headlines — with more than 7,000 cases reported in China’s Guangdong province and tens of thousands more across the Indian Ocean islands.

How does it spread, what symptoms does it cause, and could it become a risk in cooler countries like the UK?Host Karl Byrne is joined by Dr Doris Kemunto Nyamwaya from The MRC/UVRI & LSHTM Uganda Research Unit to unpack what we know about chikungunya, why public health experts are watching it so closely, and whether vaccines might change the picture.Click here to find out more about LSHTM's courses, including the MSc Epidemiology mentioned in the episode

Ever had a sudden, gut-wrenching bout of vomiting and diarrhoea? You’re not alone—norovirus, the infamous ‘winter vomiting bug,’ has been wreaking havoc across the UK. But why are cases so high this year? And how can you protect yourself?In this special episode, Karl speaks to LSHTM expert Dr Damien Tully to break down the science behind norovirus, how it spreads, and why cruise ships are often the perfect storm for outbreaks. We also discuss the latest infection figures, the strain on the NHS, and practical ways to avoid infection.Ranked 4th globally for infectious diseases in 2024, LSHTM provides a renowned learning environment with research-led teaching.

In this bonus episode of LSHTM Viral, we explore human metapneumovirus (HMPV), a respiratory virus recently making headlines due to an outbreak in China and rising cases in the UK. But is this something we should be worried about? Host Karl Byrne is joined by Professor Martin Hibberd, an expert in emerging infectious diseases at LSHTM, to break down what HMPV is, how it compares to other respiratory viruses like flu and RSV, and why it’s unlikely to cause a pandemic. They discuss how to protect yourself from seasonal respiratory infections and what global health experts are watching for in future outbreaks.

The explosive COVID-19 outbreak in India has shone a striking light on one of the biggest moral issues of our time - vaccine equity. Subsequent halting of vaccine exports is severely affecting Africa and developing countries, and although 1.9 billion doses have been administered globally, many developing countries are yet to receive a single dose. In this episode we are joined by two global health leaders, Professor Peter Piot and Dr. Ayoade Alakija, who discuss vaccine nationalism, COVID-19 in Africa, and possible routes to improving health equity in the future.

How do countries get access to COVID-19 vaccines in the first place? In this episode, Prof Daniel Bausch of LSHTM shares his thoughts on the global vaccine purchasing and distribution systems. An expert in the control of emerging viruses, Dan also discusses with host Naomi Stewart what the focus on COVID-19 means for other vaccination programmes and trials, how the pandemic may end, and how prepared we will be for future epidemics and pandemics.

This week, Karl Byrne talks about the latest vaccination figures as well as other breaking COVID-19 news, including an exciting citizen science project where over the last year gamers playing EVE Online- a massively multiplayer online role-playing game, have carried out real world research that would have taken scientists over 330 years to complete. In our main feature, Karl tells the incredible story of how the Pfizer-BioNTech is manufactured. The journey begins with a small, frozen tube of viral DNA in a facility in America's Midwest, involves travelling across states, and even continents, ending almost 2 months later with millions of doses of vaccine ready to be shipped to vaccination centres across the USA, Europe and beyond.
