Feb 25, 2026

A universal nasal spray vaccine that could block nearly all viruses, and possibly also bacteria and allergens has been successful at early stages of research. By leaving immune cells ‘on alert’, they become ready to jump into action no matter what infection tries to get into the body. Dr Matthew Fox, Professor in the Departments of Epidemiology and Global Health at Boston University, explains what this could mean for the future of disease prevention.

Four years into the Ukraine war, the founder of global initiative ‘Think Equal’ Leslee Udwin explains the programmes currently in place to help children to grow through their traumatic experiences. Plus, a teacher in Kharkiv, Violetta Kaleda, as well as some of the children within the programmes, describe the impact of bringing social and emotional learning into education.

Prevention campaigns are resuming after the cholera outbreak in Mozambique has now been declared an epidemic by the country’s national director of public health. Reporter Jose Tembe give the latest on the outbreak after the years-long shortage of cholera vaccines begins to rebound.

As commercial spaceflight grows and human fertility in space becomes a more pressing concern, embryologist Giles Palmer explains the current understanding of the effects of spaceflight on human reproductive systems. Plus, a new study on ultra-endurance marathon running shows it may accelerate aging and the breakdown of red blood cells.

Ebola outbreak in the Democratic Republic of Congo

An Ebola outbreak that started in the north-east of the Democratic Republic of Congo (DRC) is spreading in the region and has been declared a health emergency. Health Check’s Claudia Hammond has the latest with BBC reporter Emery Makumeno in Kinshasa, Heather Kerr, Country Director for the International Rescue Committee (IRC) in the DRC, and Professor Trudie Lang, head of the Global Health Network at Oxford University.

Claudia is joined in the studio by BBC health reporter Laura Foster. They discuss the call for more testing of drugs with under-represented groups, after a study of Black African Americans, smokers, and people with complex health conditions in the US showed that an asthma drug, Tezepelumab, led to 70% fewer asthma attacks in people with severe asthma.

They also hear about new hearing technology which can read peoples’ brainwaves to help people to pick out the single voice they want to listen to in a noisy room. Claudia speaks to Nima Mesgarani, Associate Professor at the Zuckerman Institute at  Columbia University in New York.

And Claudia and Laura discuss why some cancer patients would fancy a pre-consultation with an AI avatar before a consultation with their real-life doctor? It's the subject of research by Dr Adam Raben, Chair of Radiation Oncology at the Helen F Graham Cancer Center at Christiana Care in Newark, Delaware, USA; presented at the European Society for Radiotherapy and Oncology Congress.
