Robert F. Kennedy Jr. is set to appear before senators this week as he seeks confirmation for the role of Health and Human Services Secretary. Kennedy’s nomination sparked sharp opposition from the medical community, including over 20,000 signatures from physicians concerned about his past statements on vaccines. Critics, including Nobel laureates and prominent health organizations, warn that his confirmation could undermine public health and vaccine trust. As health secretary, Kennedy would oversee critical public health agencies, biomedical research, pharmaceutical regulations, and health coverage for over 160 million Americans. The Senate hearings will take place Wednesday and Thursday.
