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 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.

Messenger RNA vaccines are a newer type of vaccine technology, which was utilized by companies like Moderna and Pfizer to develop their COVID-19 vaccines. The vaccine technology was at the center of a lot of criticism amid the coronavirus pandemic for potentially being associated with adverse side effects in some people who took them, such as myocarditis.

Trump administration officials previously hinted at the potential that this funding could be terminated, citing a lack of oversight during the Biden administration pertaining to vaccine production. 

‘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.’

The announcement reflects a larger shift in federal vaccine priorities, after HHS Secretary Robert F. Kennedy Jr. announced earlier this week that COVID-19 vaccines would be removed from the federal government’s list of recommended vaccines for children and pregnant women. 

Meanwhile, a report from Senate Republicans released earlier this month suggested the Biden administration withheld critical safety data and downplayed known risks tied to the mRNA COVID-19 vaccine. In particular, the Senate report focuses on HHS’ awareness of, and response to, cases of myocarditis — a type of heart inflammation — following COVID-19 vaccination.

‘Rather than provide the public and health care providers with immediate and transparent information regarding the risk of myocarditis following mRNA COVID-19 vaccination, the Biden administration waited until late June 2021 to announce changes to the labels for the Moderna and Pfizer COVID-19 vaccines based on the ‘suggested increased risks’ of myocarditis and pericarditis,’ the Senate report states. ‘Even though CDC and FDA officials were well aware of the risk of myocarditis following COVID-19 vaccination, the Biden administration opted to withhold issuing a formal warning to the public for months about the safety concerns, jeopardizing the health of young Americans.’

In response to the Trump administration’s funding termination, Moderna put out a press release acknowledging the move, but also touting the ‘safety profile’ observed amid its work on a new mRNA bird flu vaccine.

‘While the termination of funding from HHS adds uncertainty, we are pleased by the robust immune response and safety profile observed in this interim analysis of the Phase 1/2 study of our H5 avian flu vaccine and we will explore alternative paths forward for the program,’ said Stéphane Bancel, Chief Executive Officer of Moderna. ‘These clinical data in pandemic influenza underscore the critical role mRNA technology has played as a countermeasure to emerging health threats.’
