Moderna Launches Global Phase 3 Trial of mRNA-1018, its mRNA Flu Vaccine, with CEPI Support

US Government Funding Cut, CEPI Steps In
Moderna (MRNA) lost mRNA research funding due to a sudden policy change by the US Department of Health and Human Services (HHS), but it has resumed clinical trials with support from the Coalition for Epidemic Preparedness Innovations (CEPI). The company faced a setback when the Biden administration canceled a contract with the Biomedical Advanced Research and Development Authority (BARDA), which had been increased to USD 452 million, after Donald Trump appointed vaccine skeptic Robert F. Kennedy Jr. as HHS Secretary. In response, CEPI provided USD 54.3 million in emergency funding, preventing the project from being halted. This event sets a precedent for bio companies to overcome financial risks associated with political decisions by diversifying partnerships.
Phase 3 Trial of Avian Flu mRNA Vaccine Candidate Begins
This clinical trial represents the final evaluation stage for 'mRNA-1018,' a vaccine candidate targeting the hemagglutinin (HA) protein, a key surface antigen of the avian influenza (A/H5N1) virus. The trial will involve approximately 4,000 healthy adults in the US and UK, marking the start of the Phase 3 trial. Utilizing mRNA platform technology, which can shorten development time by several months compared to traditional cell culture-based vaccines, the trial aims to validate a rapid response system for unexpected pandemics. The vaccine has already demonstrated good tolerability and reliable immunogenicity in Phase 1/2 trials, making the results of this final stage crucial for determining the technology's credibility.
Global Vaccine Market Landscape and Competitive Dynamics
The global pandemic influenza vaccine market is a high-value market, expected to grow from approximately USD 10.38 billion in 2025 to USD 16.9 billion in 2034, with an annual growth rate of 5.56%. Moderna has secured a first-mover advantage by initiating the Phase 3 trial, but it faces fierce competition from multinational pharmaceutical companies and biotech firms. Key competitors include GSK's GSK5536522 (Phase 2), Sanofi's (SNY) SP0289/SP0335 (Phase 1/2), and Pfizer's (PFE) PF-07985819 (Phase 1). Arcturus Therapeutics (ARCT) is also accelerating the development of its self-amplifying RNA (saRNA) candidate, ARCT-2304, in Phase 1, aiming to be a game-changer.
Securing Manufacturing and Supply Chains, Diversifying Commercialization Strategies
Under the terms of the investment agreement with CEPI, Moderna is obligated to allocate 20% of its total vaccine manufacturing capacity to low- and middle-income countries (LMICs) at a low price in the event of a pandemic. This fulfills the company's social responsibility by contributing to public health while also strategically positioning it to gain brand recognition and expand its global supply chain in emerging markets. If the Phase 3 data is positive, the company is likely to obtain accelerated approval by leveraging existing clinical data for seasonal influenza vaccines that are already under review by global regulatory authorities. Despite the termination of direct funding from the US government, the company has demonstrated its resilience by securing alternative public funding and maintaining its commercial independence.
Despite the political risk of the US government's cancellation of a USD 452 million BARDA funding agreement, Moderna's ability to secure USD 54.3 million in alternative funding from CEPI and initiate Phase 3 trials demonstrates the resilience and flexibility of its mRNA platform. This provides an opportunity to secure a first-mover position in the pandemic influenza vaccine market, which is expected to be worth approximately USD 10.38 billion in 2025. However, with competitors such as Pfizer's PF-07985819 and Sanofi's SP0289 in Phase 1/2 trials, the timing of final approval will be a key factor. The CEPI agreement to allocate 20% of manufacturing capacity to low- and middle-income countries presents both an opportunity to establish a global supply chain and a short-term limitation on profit margins. The possibility of leveraging existing clinical data for seasonal influenza vaccines to obtain accelerated approval will significantly impact the commercialization speed and research and development capabilities of subsequent mRNA pipelines.
