Robert F. Kennedy Jr. is Donald Trump's pick for HHS Secretary, with unique policy priorities separate from Trump's, and Trump's promise to let him 'go wild' on his ideas. The HHS Secretary has significant power over health regulations, public health emergencies, and shaping public opinion. Kennedy's controversial stance on vaccines, criticizing their safety despite extensive research proving otherwise, could risk public health. He advocates for individual vaccine decisions, which could lead to community risks, especially for immunocompromised individuals. Kennedy also links chemicals in food to autism and mental health, areas of ongoing research. He criticizes fluoride in drinking water, despite its safety and benefits for dental health. Kennedy misunderstands FDA authority, criticizing its regulation of drugs and supplements. Trump envisions Kennedy ending the chronic health epidemic, potentially through regulating food additives and ultraprocessed foods, though political and industry influences may hinder this.
