US Health Secretary Robert F. Kennedy Jr. canceled $500 million in mRNA vaccine research funding, sparking debate. Critics, including leading vaccine researchers, deem this a "stupid" and potentially catastrophic decision, arguing that while mRNA vaccines aren't perfect and were perhaps overhyped during the pandemic, they remain a vital technology with proven life-saving capabilities. They contend that the technology's limitations, such as needing updates for evolving viruses, are not unique to mRNA vaccines and that abandoning them would be a grave mistake.
