Cancer vaccine news is the advance we’ve been waiting for
Merck and Moderna's mRNA cancer vaccine, intismeran, showed success in a phase 3 trial for melanoma, extending time before recurrence and metastasis. The vaccine, combined with Keytruda, reduced melanoma recurrence by 49% in a smaller study. Moderna's stock more than doubled following the news. Full data will be shared at an upcoming medical meeting. The companies are also testing the vaccine in other cancers.
