Detailed Narrative
Regulatory Headwinds for Flu Program
The FDA issued a Refusal-to-File letter for Moderna's seasonal flu vaccine, mRNA-1010, in the U.S., citing regulatory uncertainty🌐. This decision creates challenges for the company's U.S. market entry for flu, though the vaccine is under review in Europe, Canada, and Australia. Moderna has requested a Type A meeting with the FDA to clarify the path forward, with the process typically taking 30 days.
Strategic International Expansion
Moderna is expanding its global footprint through strategic agreements, including a 5-year respiratory vaccine supply deal with Mexico and a recent agreement with Taiwan. These partnerships, along with local manufacturing in the U.K. and Australia starting in 2026, are expected to drive significant international revenue growth. The company also anticipates the European respiratory vaccines market, valued at $1.8 billion, to open up in 2027.
Oncology Pipeline Progress
The company reported positive 5-year Phase II data for intismeran (individualized cancer therapy) in adjuvant melanoma, demonstrating durability with approximately a 50% reduction in relapse or death. Enrollment is complete for Phase II studies in muscle invasive bladder cancer, adjuvant renal cell carcinoma, and adjuvant melanoma, with data readouts anticipated in 2026. The cancer antigen therapy mRNA-4359 is now in Phase II, and Dr. David Berman will join as Chief Development Officer to further expand the oncology pipeline.
Infectious Disease Pipeline
Beyond COVID, Moderna's infectious disease pipeline is advancing. The norovirus program is fully enrolled in Phase III, with data expected in 2026. The propionic acidemia (PA) program is also fully enrolled in its registrational study, with data expected in 2026. The flu/COVID combination vaccine (mRNA-1083) is under review in Europe and Canada, with potential approvals in 2026.
Cost Discipline and Efficiency
Moderna achieved a 30% reduction in operating expenses in 2025, totaling $2.2 billion, and expects cash costs to decline further to $4.2 billion in 2026. The company attributes these efficiencies, in part, to the adoption of AI tools across its business operations. This cost discipline contributed to ending 2025 with $8.1 billion in cash and investments, exceeding prior guidance.
mNEXSPIKE Commercial Success
The new COVID vaccine, mNEXSPIKE, had a successful U.S. launch in 2025, capturing 24% of the total U.S. retail market and 34% among adults aged 65 and older. The retail market represents approximately 75% of the U.S. COVID market. The company expects continued uptake in the U.S. and international approvals and launches in multiple countries in 2026 and beyond, including Europe, Japan, and Taiwan.
