STORY: :: Why Moderna and Merck's cancer vaccine trial may be a milestone :: New York / August 19, 2026 :: Michele Gershberg, Global Health Editor "The two drugmakers, Moderna and Merck, gave an overview of a clinical trial that was testing a new cancer vaccine, together with a widely used cancer treatment from Merck called Keytruda. It was testing it in melanoma patients, and, it was a large trial. And they said that what they found is that it works better than just Keytruda by itself, when it comes to preventing the disease from returning, or from spreading to other parts of the body." // "The trial itself was looking at patients who had just had their tumors removed surgically. // At the moment, Moderna has told us that they expect that there are thousands of patients who could benefit from this if they receive regulatory approval. And that approval, their aim is to get it sometime in 2027." // "This is designed to treat melanoma.

mRNA cancer vaccines
Two major drug companies successfully tested a new vaccine that helps prevent skin cancer from returning when paired with an existing drug. Wall Street cares because this could become a brand-new medical product generating billions in sales if approved.

Moderna and Merck released promising clinical trial data showing their combination mRNA cancer vaccine and Keytruda outperform Keytruda alone in preventing melanoma recurrence.
Who wins / who loses
Moderna and Merck benefit from strong trial validation, while traditional standalone immunotherapy developers face heightened competitive pressure.
