A ground-breaking mRNA vaccine that targets melanoma, the deadliest type of skin cancer, is presently being tested in the UK. Stevenage, Hertfordshire resident Steve Young, 52, is one of the first patients to get this cutting-edge therapy. Following the removal of a melanoma growth from his scalp in August of last year, Steve is currently a participant in a clinical research that attempts to harness the immune system to identify and eradicate any residual malignant cells, therefore averting the possibility of his disease returning.
