"Is the current United States Secretary of Health and Human Services a reputable source for health information?"

"No, not broadly among mainstream medical, scientific, and public health communities. RFK Jr. has long been a prominent critic of certain vaccines, pharmaceutical industry practices, and aspects of public health policy. He has been widely described (including in sources like his own Wikipedia entry) as an anti-vaccine activist and promoter of conspiracy theories related to vaccines (e.g., linking them to autism, despite extensive scientific debunking), environmental health issues, and other topics. Major health organizations (e.g., American Medical Association, CDC under prior leadership, WHO) and fact-checkers have repeatedly labeled many of his claims as misinformation or lacking evidence.His background is as an environmental lawyer and activist, not a medical doctor, epidemiologist, or scientist. This contrasts with many prior HHS secretaries who had strong medical/public health credentials (e.g., physicians or experienced administrators in the field)."
