Moderna Announces Global Regulatory Submissions for Its Investigational Seasonal Influenza Vaccine

CAMBRIDGE, MA /ACCESS Newswire/ January 5, 2026 /Moderna, Inc. (NASDAQ:MRNA) today provided an update on regulatory submissions for its investigational seasonal influenza vaccine, mRNA-1010, for adults aged 50 years and older. The Company has filed for marketing authorization with the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), Health Canada, and the Therapeutic Goods Administration (TGA) in Australia.

"We are proud to announce these filings for the use of our seasonal flu vaccine candidate, a major milestone for our respiratory portfolio," said Stéphane Bancel, Chief Executive Officer of Moderna. "The issue of vaccine mismatch due to virus mutations has long worried influenza experts and, as we have seen this flu season, can lead to a heightened public health burden. The agility and flexibility of mRNA technology offer the potential to more closely match evolving strains and more effectively respond to one of the world's most persistent respiratory threats. If approved, this potential new product launch and geographic expansion represent an important opportunity to support Moderna's continued growth in 2027 and beyond."

The regulatory applications are based on positive data from multiple Phase 3 studies. In a Phase 3 efficacy study (P304), mRNA-1010 achieved the most stringent superiority criterion prespecified in the protocol, with a relative vaccine efficacy (rVE) of 26.6% (95% CI; 16.7%, 35.4%) across all adults aged 50 years and older. Subgroup analyses confirmed a consistently strong rVE point estimate across age groups, risk factors and previous influenza vaccination status. In participants aged 65 years and older, mRNA-1010 demonstrated an rVE of 27.4%. In a previous Phase 3 study (P303), mRNA-1010 had demonstrated superior seroconversion rates and geometric mean titer ratios (GMR) against all strains included in the vaccine compared to both high-dose and standard-dose licensed seasonal influenza vaccine.

mRNA-1010 has been found to be well tolerated with a favorable safety profile. The majority of solicited adverse reactions (SARs) have been mild. Injection site pain was the most common local SAR, and fatigue, headache and myalgia were the most common systemic SARs reported.
