HHS Cancels moderna Flu Vaccine Contract, Raising Pandemic concerns

Updated May 29, 2025

The Department of Health and Human Services​ (HHS) has informed Moderna of its decision to cancel a nearly $600 million contract. The agreement aimed to develop, test, and license vaccines targeting influenza strains, including the⁣ H5N1 bird flu ⁢virus, that ⁣pose a pandemic threat.

While HHS ⁤signaled ‍a ‌possible review of⁢ the contract, initially⁤ signed ‌under‍ the Biden administration, back ⁤in February, the cancellation is viewed as a ‍setback for U.S. pandemic⁣ preparedness. ‍The contract focused on developing a novel flu vaccine.

The​ speed at which messenger‌ RNA (mRNA) platforms, like⁤ Moderna’s, can ⁤produce⁤ vaccine doses is unmatched by other⁣ methods. However, Health Secretary Robert F. Kennedy⁣ Jr.⁤ and his supporters reportedly harbor reservations about mRNA vaccine technology and its role in future⁤ pandemic responses. The cancellation raises questions about⁤ the future role of mRNA vaccines.
