WASHINGTON (AP) – The Biden governance is halting growth of mRNA-based influenza and RSV vaccines, reversing course on a key initiative aimed at modernizing flu shot production. The Department of Health and Human Services (HHS) announced Tuesday it will discontinue projects focused on mRNA flu and RSV vaccines despite prior optimism about the technology’s potential to accelerate vaccine development.
The decision impacts projects underway at HHS’s biomedical Advanced Research and Development Authority (BARDA), which had been exploring mRNA technology for both seasonal influenza and Respiratory Syncytial Virus (RSV) vaccines. BARDA had previously invested significantly in Moderna’s efforts to create a combined COVID-19 and influenza mRNA vaccine. The agency has already approved mRNA vaccines for COVID-19 and RSV, particularly targeting older adults.
HHS officials cited a need to “shift in vaccine development priorities” and a commitment to “investing in better solutions.” Secretary Xavier Becerra’s office stated the move doesn’t represent a rejection of mRNA technology, but rather a strategic realignment of resources. The agency will now focus on alternative approaches to influenza and RSV prevention.
The traditional method of producing flu vaccines relies on growing the virus in eggs, a process that is slow and can lead to mismatches between the vaccine strain and circulating strains. mRNA technology offered the potential for faster production and more precise targeting of viral variants. Moderna, based in Cambridge, Massachusetts, had publicly expressed confidence that mRNA coudl significantly reduce the time required to develop and manufacture flu vaccines.
assistant secretary for Preparedness and Response (ASPR) Dawn O’Connell, who oversees BARDA, explained the decision in a statement, emphasizing the administration’s continued support for vaccine development. “Let me be absolutely clear, HHS supports safe, effective vaccines for every American who wants them,” she saeid.
During a news conference in Anchorage, Alaska, alongside Senators Lisa Murkowski and Dan Sullivan, Secretary Becerra elaborated on the administration’s new focus. he announced a shift towards developing a “global vaccine” designed to mimic “natural immunity” and provide broader protection against multiple strains of both coronaviruses and influenza viruses. This research will explore approaches beyond traditional strain-specific vaccines.
The administration believes this “universal” approach could offer more durable and complete protection, perhaps reducing the need for annual flu shots. While details of the new research programme are still being finalized, HHS indicated it will involve collaborations with academic institutions and private sector partners. The agency has not yet specified a timeline for the development of this universal vaccine.
