The appointment of Robert F. Kennedy Jr., a known vaccine skeptic, as Secretary of Health and Human Services in Donald Trump's Cabinet has elicited widespread shock and concern within the medical community. Dr. Sanjay Gupta, CNN's chief medical correspondent, highlighted the 'horror' felt by many health professionals, emphasizing Kennedy's controversial views on vaccines and public health. Critics are worried about Kennedy's history of promoting conspiracy theories, including claims about vaccines being linked to autism, which contradict established medical science. Despite these concerns, some supporters, like Dr. Mehmet Oz, argue that Kennedy's appointment could address issues of corporate influence in health agencies. Shares of vaccine manufacturers like Pfizer and Moderna fell following the news, reflecting market apprehension. The appointment still requires Senate confirmation, although Trump has considered bypassing this process via recess appointments.
