In a controversial move, Robert F. Kennedy Jr. announced the cancellation of $500 million in federal funding for mRNA vaccine research, a decision that has drawn sharp criticism from health experts and former officials. While Kennedy justifies the cuts by questioning the reliance on scientific expertise, public health authorities warn that this rollback represents a dangerous public health decision that could undermine future medical breakthroughs. The former Surgeon General expressed dire concerns, stating that lives will be lost as a result of halted research. The cuts have incited a complex debate about trust in scientific authorities and the future of vaccine development in the U.S., as other nations consider stepping in to fill the funding void left by the American government.
