A pivotal meeting on vaccine guidance is underway—and former CDC leaders are alarmed

Former CDC leaders Susan Monarez and Debra Houry testified in a Senate hearing about their abrupt departures from the agency, citing concerns about CDC employees ignoring scientific evidence. Monarez expressed worries about potential threats to childhood vaccine access and the resurgence of preventable diseases if vaccine protections are weakened. The current Secretary of Health and Human Services, Robert F. Kennedy Jr., has been criticized for his stance on vaccines and recent changes to the CDC's Advisory Committee on Immunization Practices. The ongoing discussions on vaccine recommendations could significantly impact vaccine access for children and vulnerable populations in the US, with implications for public health and trust in vaccines.
