The company plans to resubmit the application later this year, incorporating efficacy data from an ongoing Phase 3 trial of its standalone seasonal influenza vaccine, mRNA-10102. Interim results from this trial are expected to be available by summer.<\/p>\n\n\n\n<p>The decision follows discussions with the FDA, which recently introduced stricter guidelines for COVID-19 vaccine approvals. The agency now requires placebo-controlled studies for any new COVID-19 vaccine seeking approval for healthy adults under 65 years old. Moderna had initially filed for approval last year, aiming for a November 2025 authorization, but the FDA&#8217;s request for additional efficacy data pushed the expected approval date to 20262.<\/p>\n\n\n\n<p>Moderna\u2019s flu\/COVID combination vaccine had previously demonstrated promising results, showing comparable or superior antibody responses against flu strains and the Omicron XBB.1.5 COVID-19 variant compared to existing flu and COVID vaccines. Despite this, the FDA&#8217;s requirement for further efficacy data led Moderna to voluntarily withdraw its application rather than amend the existing submission1.<\/p>\n\n\n\n<p>The withdrawal is a setback for Moderna, which has been facing declining revenue from its COVID-19 and RSV vaccines. Following the announcement, Moderna\u2019s stock initially rose by more than 6% but later lost those gains1. The company remains optimistic about its resubmission later this year, once the necessary efficacy data is available.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Moderna has withdrawn its application for FDA approval of its combination flu and COVID-19 vaccine, mRNA-1083, for adults aged 50 and older.
