It's the day after one of the surprise healthcare stories of 2026.
Moderna (MRNA) shares fell 20% in early trading on Thursday after a stunning 177% gain yesterday on news that the biotech and partner Merck (MRK) notched a big breakthrough in the fight against cancer.
The pair announced that their personalized mRNA cancer vaccine — called intismeran — successfully hit its primary goal in a Phase 3 late-stage trial, demonstrating a meaningful reduction in melanoma recurrence in patients who had already had their tumors surgically removed.
The trial compared using intismeran alongside Merck's well-known immunotherapy drug Keytruda against using Keytruda alone. Patients who received the combination lived meaningfully longer without their cancer returning or spreading.
"It's a home run, maybe even a grand slam," Dr. Ezekiel Emanuel said on Yahoo Finance (video above). "The results are pretty amazing."
