HHS slams 'under-tested' mRNA technology as Trump cuts Moderna's H5N1 vaccine funding | 28 May 2025 | President Donald Trump's Department of Health and Human Services (HHS) is terminating awards totaling more than $750 million dollars that were provided to pharmaceutical manufacturer Moderna to help facilitate its production of mRNA-based bird flu vaccines. During President [sic] Joe Biden's final week in office, his administration awarded $590 million to Moderna to help speed up its production of mRNA-based vaccines. The $590 million award followed a separate $176 million award Biden gave to Moderna earlier last year for mRNA vaccine technology. "After a rigorous review, we concluded that continued investment in Moderna's H5N1 mRNA vaccine was not scientifically or ethically justifiable," HHS Communications Director Andrew Nixon said. "This is not simply about efficacy -- it's about safety, integrity, and trust. The reality is that mRNA technology remains under-tested, and we are not going to spend taxpayer dollars repeating the mistakes of the last administration, which concealed legitimate safety concerns from the public."
