The article discusses Health and Human Services Secretary Robert F. Kennedy Jr.’s recent decision to cancel $500 million in mRNA vaccine research contracts, which has been criticized as a major setback for American science. Kennedy’s claims about mRNA vaccines being ineffective and causing health issues lack data support, according to several experts. While some argue that the cancellations won’t significantly hinder vaccine development, others warn that the broader threats to vaccines, including changes in vaccine advisory boards and increased scrutiny, could deter future research. The situation reflects a growing anti-science sentiment tied to right-wing distrust of official narratives. This environment has caused many scientists to consider relocating their labs overseas due to safety and funding concerns.
