The U.S. Department of Health and Human Services (HHS) announced termination of 22 Biomedical Advanced Research and Development Authority (BARDA) contracts totaling nearly $500 million dedicated to mRNA vaccine development. Secretary Robert F. Kennedy Jr. cited concerns over the vaccines’ effectiveness against upper respiratory infections such as COVID-19 and influenza, signaling a pivot toward broader, non-mRNA vaccine platforms. This decision, made despite extensive clinical evidence supporting mRNA vaccine efficacy and safety, sparked significant concern within the scientific and medical communities about the future of mRNA vaccine technologies, including applications in cancer and other diseases. The funding cuts follow prior cancellations of contracts with major mRNA vaccine developers Moderna and Pfizer, raising questions about U.S. preparedness for future pandemics and bioterrorism threats.
