How does Moderna’s new melanoma vaccine work – and could it treat other cancers?

Moderna and Merck's experimental mRNA cancer vaccine, intismeran, showed promise in a phase 3 trial for high-risk melanoma patients. The personalized vaccine, combined with Keytruda, aims to train the immune system to target cancer cells. Early results indicate extended cancer-free periods, but long-term effects are unclear. Trials for lung, bladder, and kidney cancers are also underway.
