Donald Trump’s nomination of Robert F. Kennedy Jr. as Secretary of Health and Human Services has ignited intense backlash due to Kennedy’s anti-vaccine stance and conspiracy theories about health. Critics, including Public Citizen, warn that his policies could jeopardize public health, especially regarding vaccine safety and NIH research. Kennedy’s past comments on food safety and alternative treatments add complexity to his views. As discussions grow around the implications of a potential second Trump term, health professionals emphasize the importance of science-based medicine in government health policies.
