The U.S. Department of Health and Human Services is responsible for protecting the health of the American people. But over the past year, it has taken several steps that critics say undermine that very objective. In today’s episode of Science Quickly, we take a close look at the man at the center of those actions—Secretary of Health and Human Services Robert F. Kennedy, Jr.—who’s spent several years sowing confusion over vaccines and propping up fringe health theories. His beliefs, some critics say, echo “soft eugenics.” SciAm senior editor Dan Vergano, Ars Technica senior health reporter Beth Mole and historian Robert Johnston join host Kendra Pierre-Louis to unpack RFK, Jr.’s ideology and its repercussions on Americans’ health.
