Penn helped test a promising mRNA cancer vaccine. Here’s what the trial means for the field.

Merck and Moderna's mRNA cancer vaccine, intismeran autogene, showed positive results in a late-stage trial, extending survival time without cancer recurrence or spread. The vaccine, tested on melanoma patients, trains the immune system to target cancer cells. Full results will be presented at the 2026 European Society for Medical Oncology meeting. The trial involved 1,137 participants, with two-thirds receiving the vaccine alongside Keytruda, a standard immunotherapy.
