Dementia is currently the leading cause of death in the UK, but could a vaccine one day help prevent it? New data from Wales shows the shingles vaccine is associated with a 20% reduction in the risk of developing dementia later in life, adding to evidence that viral infections can affect brain health. Dr Pascal Geldsetzer, Associate Professor of Medicine at Stanford University, discusses his findings and the additional evidence needed to prove this link with Professor Tara Spiers-Jones, group leader at the UK Dementia Research Institute. The UK has begun using the world's first gonorrhea vaccine, although it was originally developed to treat meningitis. With antibiotic-resistant strains on the rise, we spoke to Dr. Sunita Soni about why gonorrhea is so difficult to treat with vaccines. At the Bristol Robotics Laboratory, engineers are creating devices to support mobility in old age. James meets Jonathan Rossner and tries out the Right Pants, an inflatable exoskeleton designed to help people walk and strengthen their muscles.
