Promising results from skin cancer vaccine trial.

A vaccine trial for melanoma appears to reduce the recurrence of skin cancer, according to a study published in the journal Nature Medicine. The vaccine, which uses immunotherapy to stimulate the immune system to attack cancer cells, was tested on 120 patients who had undergone surgery to remove melanoma. The trial found that the vaccine reduced the risk of recurrence by 30% compared to a control group. The researchers hope that the vaccine could eventually be used to prevent the spread of melanoma to other parts of the body.
