Arizona Tribune - Moderna Receives European Commission Marketing Authorization for mCOMBRIAX, Moderna's mRNA Combination Vaccine Against Influenza and COVID-19

CAMBRIDGE, MA / ACCESS Newswire / April 21, 2026 / Moderna, Inc. (NASDAQ:MRNA) today announced that the European Commission (EC) has granted marketing authorization for mCOMBRIAX^® (mRNA-1083), the Company's mRNA combination vaccine for active immunization for the prevention of influenza disease and COVID-19 caused by SARS-CoV-2 in individuals 50 years of age and older.

This marketing authorization follows the positive opinion from the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) and is valid in all 27 European Union member states, as well as Iceland, Liechtenstein and Norway. mCOMBRIAX is Moderna's fourth authorized product, further strengthening the Company's respiratory portfolio and commitment to the European Union.

"We welcome the European Commission's approval of mCOMBRIAX, the world's first flu plus COVID-19 combination vaccine," said Stéphane Bancel, Chief Executive Officer of Moderna. "By combining protection against two significant respiratory viruses in a single dose, our vaccine aims to simplify immunization for adults, particularly those at high risk. mCOMBRIAX offers an important new option for Europeans, while also aiming to strengthen the resilience of healthcare systems across Europe."

mCOMBRIAX builds on the advances from the clinical development of mNEXSPIKE^®, Moderna's COVID-19 vaccine, and mRNA-1010, Moderna's investigational seasonal influenza vaccine, which has been accepted for review in the European Union, United States, Canada and Australia.

The EC's authorization is based on the results from the pivotal Phase 3 clinical trial (ClinicalTrials.gov Identifier: NCT06097273), a randomized, observer-blind, active-controlled study evaluating the safety, reactogenicity, and immunogenicity of mRNA-1083 in two independent age cohorts of approximately 4,000 adults each. One cohort included adults 65 years of age and older and compared mRNA-1083 to co-administered Fluzone HD^® (licensed in the European Union as Efluelda^®), a high-dose influenza vaccine, and Spikevax^®, Moderna's licensed COVID-19 vaccine. The second cohort included adults 50 to 64 years of age and compared mRNA-1083 to co-administered Fluarix^®, a standard-dose influenza vaccine, and Spikevax.

All primary endpoints demonstrating the non-inferiority of immune responses were met. Following a single dose, mRNA-1083 elicited statistically significantly higher immune responses against three influenza virus strains (A/H1N1, A/H3N2, and B/Victoria) and against SARS-CoV-2 in both age cohorts. The B/Yamagata strain, which is no longer recommended for inclusion in seasonal influenza vaccines, was the only strain for which a statistically significantly higher immune response was not observed for adults 65 years of age and older compared to the co-administered licensed comparator vaccines.^[1]

mRNA-1083 demonstrated an acceptable safety and tolerability profile. The majority of solicited adverse reactions were grade 1 or 2 in severity and consistent with the licensed vaccines used in the trial.

mCOMBRIAX will be made available across the European Union, subject to national regulatory and access procedures, with Moderna working closely with national authorities to support local access and implementation.
