Moderna, Inc.: Moderna Receives U.S. FDA Approval for Influenza Vaccine mFLUSIVA

mFLUSIVA becomes Moderna's fifth approved product globally and fourth FDA-approved product

Company expects supply to be available in select retailers in the coming weeks

CAMBRIDGE, MA / ACCESS Newswire / August 5, 2026 / Moderna, Inc. (NASDAQ:MRNA) today announced that the U.S. Food and Drug Administration (FDA) has approved mFLUSIVA (mRNA-1010), a new vaccine against seasonal influenza, for use in all adults 50 years and older. This approval follows unanimous recommendations from the FDA's Vaccines and Related Biological Products Advisory Committee (VRBPAC) supporting mFLUSIVA for adults 50 years of age and older.

"The FDA approval of mFLUSIVA, our fourth approved product in the United States and the first mRNA-based flu vaccine, demonstrates the continued strength and versatility of our mRNA platform," said Stéphane Bancel, Chief Executive Officer of Moderna. "Flu remains a significant public health challenge, and mFLUSIVA provides an important new option for America's seniors. This approval also reflects the ongoing potential of our mRNA platform to help address important public health challenges through continued scientific innovation. We are grateful to the clinical trial participants, investigators, regulators and Moderna teams whose contributions made this milestone possible."

The FDA's approval of mFLUSIVA in adults 50 through 64 years of age is based on results from a randomized, observer-blind, active-controlled, Phase 3 clinical trial (ClinicalTrials.gov Identifier: NCT06602024), which enrolled 40,805 adults aged 50 years and older across 11 countries. The primary objectives in this study were to evaluate the safety and reactogenicity of mFLUSIVA, and to evaluate relative vaccine efficacy (rVE) of mFLUSIVA versus a standard dose (SD) active comparator against reverse transcription polymerase chain reaction (RT-PCR)-confirmed protocol-defined influenza-like illness (ILI) caused by any influenza A or B strains.

Use in adults 65 years of age and older was granted accelerated approval based on results from a randomized, observer-blind, active-controlled clinical trial (ClinicalTrials.gov Identifier: NCT05827978), which enrolled 2,992 adults 65 years of age and older in the United States. The primary objective in this study was to evaluate the immunogenicity of mFLUSIVA versus a high-dose (HD) inactivated influenza vaccine comparator. The effectiveness of mFLUSIVA in adults 65 years of age and older is also supported by the descriptive analysis of rVE in the randomized, observer-blind, active-controlled, Phase 3 clinical trial (ClinicalTrials.gov Identifier: NCT06602024). Confirmation of clinical benefit in this population will be assessed in a postmarketing clinical trial.

The Phase 3 program demonstrated an acceptable safety profile for mFLUSIVA, with no new safety concerns identified, consistent with previously reported studies of mFLUSIVA.

Moderna expects to have mFLUSIVA available for eligible populations in the U.S. for the 2026-2027 respiratory virus season, alongside Spikevax (COVID-19 Vaccine, mRNA), mRESVIA (Respiratory Syncytial Virus Vaccine) and mNEXSPIKE (COVID-19 Vaccine, mRNA).

mRNA-1010 has been accepted for regulatory review in the European Union, Canada and Australia. Regulatory submissions in additional countries are planned during 2026.

INDICATION

What is mFLUSIVA (Influenza vaccine, mRNA)?

mFLUSIVA is a vaccine indicated for active immunization for the prevention of influenza disease caused by influenza virus subtypes A and type B represented in the vaccine. mFLUSIVA is approved for use in persons 50 years of age and older.

The indication for persons 65 years of age and older is approved under accelerated approval based on immune responses. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

IMPORTANT SAFETY INFORMATION

You should not get mFLUSIVA if you had a severe allergic reaction to any ingredient in mFLUSIVA.

Tell your healthcare provider about all of your medical conditions, including if you:

• have any allergies or have had a severe allergic reaction after receiving a previous dose of any other vaccine

• have had Guillain-Barré syndrome (severe muscle weakness) after getting an influenza vaccine

• are immunocompromised or are on a medicine that affects your immune response

• are breastfeeding, pregnant or plan to become pregnant

• have ever fainted in association with an injection

What are the risks of mFLUSIVA?

Severe allergic reactions are rare but can happen after vaccination with mFLUSIVA. If a severe allergic reaction occurs, it would usually happen within minutes to one hour after a dose of mFLUSIVA. Because of this, your healthcare provider may ask you to stay for a short time after your vaccination.

Side effects that have been reported in clinical trials with mFLUSIVA include:

Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm as the injection, swelling (hardness), and redness.

General side effects: fatigue, headache, muscle pain, joint pain, chills, nausea or vomiting, and fever.

These may not be all the possible side effects of mFLUSIVA. Ask your healthcare provider about any side effects that concern you. You may report side effects to Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967 or http://vaers.hhs.gov.
