• The Trump administration has canceled a $766 million contract with Moderna for developing a bird flu vaccine.
• This decision forfeits the U.S. right to purchase doses prior to a pandemic.
• Health Secretary Robert F. Kennedy Jr. expressed skepticism about mRNA vaccine safety.
• Despite positive interim results from Moderna's trials, funding has been withdrawn.
• Concerns over the potential for the H5N1 virus to mutate and become more dangerous remain prevalent.

The Trump administration has terminated a $766 million contract with Moderna for the development of a vaccine against potential pandemic influenza viruses, including the H5N1 bird flu. The decision, announced recently, marks a significant blow to the ongoing efforts to prepare for a possible avian flu pandemic, as it eliminates the U.S. government's right to purchase doses in advance, according to NPR and Los Angeles Times.

The contract, which would have supported a late-stage clinical trial for an mRNA vaccine named mRNA-1018, was previously awarded through the Biomedical Advanced Research and Development Authority (BARDA). Health Secretary Robert F. Kennedy Jr. has voiced skepticism regarding mRNA technology, which has been effectively utilized in COVID-19 vaccinations, despite significant evidence that these vaccines are safe, according to India Times and New York Times.

Moderna had recently reported encouraging interim results from a clinical trial involving 300 healthy adults, showing a robust immune response. However, as reported, the funding withdrawal has led the company to consider alternative paths for the vaccine’s development amid growing concerns about the ongoing mutations of the H5N1 virus and its potential to infect humans, according to CBS News and HuffPost.

Experts caution that transmittable mutations of the H5N1 virus could lead to a pandemic, with reports indicating that last year the virus spilled from wild birds into cattle across several U.S. states, infecting hundreds of animals and leading to cases in at least 70 humans, exemplifying the urgency of sufficient vaccine development efforts, as highlighted by Channel News Asia and HuffPost.
