Health and Human Services Secretary Robert F. Kennedy Jr. said Tuesday he’s canceling contracts and funding for 22 vaccines developed using mRNA technology, including the COVID-19 shots that saved millions of lives after their rapid development in 2020. The funding cuts could also impact research into using mRNA to treat other diseases, including cancer. This comes just a week after Senate Democrats launched an investigation into RFK Jr.’s firing of a CDC vaccine advisory panel, replacing them with unqualified appointees, many with anti-vaccine views.
