As Diabetes Awareness Week begins today, a 'diabetes vaccine' is undergoing clinical trials at the University Hospital of Wales, Cardiff, in the hope that it might eventually lead to a cure.

Scientists are working to develop a vaccine to slow or halt the autoimmune process that destroys the insulin-making cells in Type 1 diabetes.

More than 160,000 people in Wales have been diagnosed with diabetes - nearly five per cent of the population.

It is estimated that 66,000 more could have the condition but have not yet been diagnosed.
