President-elect Donald Trump says he will nominate anti-vaccine activist Robert F. Kennedy Jr. to serve as secretary of the Department of Health and Human Services.

While Kennedy insists he is not anti-vaccine and claims he has never advised the public to avoid vaccination, he has repeatedly expressed opposition to vaccines. On a podcast, he stated, "There's no vaccine that is safe and effective" and has urged people to resist CDC guidelines on childhood vaccination schedules.

President-elect Donald Trump has picked Robert F. Kennedy Jr. to be his next secretary of the Department of Health and Human Services, a choice that would add to Trump’s list of provocative picks whose confirmation processes will test the loyalty of Senate Republicans.
