Merck · 26 big moves · since May 2026

MRK ripped 12.6 percent today, and this one has a clear, clinical reason behind it. Merck and Moderna reported positive results from their combination therapy — intismeran autogene, a personalized mRNA cancer vaccine, paired with Keytruda, Merck's blockbuster immunotherapy. The personalized part matters: this isn't a one-size-fits-all vaccine. It's built from a patient's own tumor mutation profile, which is why a positive readout moves stocks this hard. Keytruda already generates roughly 25 billion dollars a year for Merck, so a vaccine that extends its reach into earlier treatment settings is a genuinely large opportunity. Pfizer and BioNTech moved higher in sympathy — the win validates the whole category. The question now: how fast can Merck scale manufacturing for something that's, by definition, made one patient at a time.
