Patients with advanced skin cancer could be fast-tracked to take part in a "revolutionary" trial of a new cancer vaccine.
The needle-free injection boosts the immune system's response and helps it attack and recognise cancer cells to help stop the disease returning.
The trial is being coordinated by the Southampton Clinical Trials Unit, which is based at the city's university, and is aiming to expand the number of patients able to take part.
Melanoma is the fifth most common cancer in the UK and accounts for about 4% of all new cancer cases but research shows it is on the rise.
