What are the main concerns and implications surrounding Robert F. Kennedy Jr.'s confirmation as Secretary of Health and Human Services?

Robert F. Kennedy Jr. was confirmed as Secretary of Health and Human Services in a narrow 52-48 Senate vote, with all Democratic senators and Republican Senator Mitch McConnell opposing his nomination. The primary concerns center on Kennedy's lack of formal medical training and his controversial vaccine skepticism, including debunked claims linking vaccines to autism and fluoride to health issues. Despite the opposition, Kennedy has gained support from the "Make America Healthy Again" movement, particularly for his criticism of food additives and his pledge to combat chronic diseases while reducing Big Pharma's influence on federal health agencies. His appointment gives him oversight of crucial agencies like the FDA and NIH, potentially reshaping American health policy under Trump's directive to "go wild on food, health and medicine."
