The Department of Health and Human Services—under the control of anti-vaccine advocate Robert F. Kennedy Jr.—has canceled millions of dollars in federal funding awarded to Moderna to produce an mRNA vaccine against influenza viruses with pandemic potential, including the H5N1 bird flu currently sweeping US poultry and dairy cows.
Last July, the Biden administration’s HHS awarded Moderna $176 million to “accelerate the development of mRNA-based pandemic influenza vaccines.” In the administration’s final days in January, HHS awarded the vaccine maker an additional $590 million to support “late-stage development and licensure of pre-pandemic mRNA-based vaccines.” The funding would also go to the development of five additional subtypes of pandemic influenza.
On Wednesday, as news broke that the Trump administration was reneging on the contract, Moderna reported positive results from an early trial of a vaccine targeting H5 influenza viruses. In a preliminary trial of 300 healthy adults, the vaccine candidate appeared safe and boosted antibody levels against the virus by 44.5-fold.
An HHS spokesperson said that the decision to cancel the funding—which would support thorough safety and efficacy testing of the vaccines—was because the vaccines needed more testing.
“This is not simply about efficacy—it’s about safety, integrity, and trust.” HHS spokesperson Andrew Nixon told The Washington Post. “The reality is that mRNA technology remains under-tested.”
Nixon went on to claim that the Trump administration wouldn’t repeat the “mistakes of the last administration, which concealed legitimate safety concerns.” The accusation refers to mRNA-based COVID-19 vaccines, which were developed and initially released under the first Trump administration. They have since been proven safe and effective against the deadly virus.
