Robert F. Kennedy Jr.'s tenure at the Department of Health and Human Services has been a direct assault on public health and scientific integrity. He has dismantled key advisory committees like the Advisory Committee on Immunization Practices, stalling critical vaccination efforts and eroding public trust. Biomedical research through the National Institutes of Health has been derailed, with important studies terminated or defunded. Kennedy has spread dangerous misinformation about vaccines, defunded childhood vaccination programs during a deadly measles outbreak, and pushed an unethical "autism registry" built on pseudoscience. His denigrating statements about autism spectrum disorder are abhorrent. Kennedy's actions endanger the health and lives of all Americans by undermining our public health infrastructure and scientific progress. His immediate resignation is imperative to restore credibility and undo the severe damage he has caused. Reinstate scientific expertise by appointing credible experts committed to evidence-based policymaking.
