Since Robert F. Kennedy Jr. was sworn in to lead the U.S. Department of Health and Human Services one year ago, he has defended his upending of federal health policy by saying the changes will restore trust in America’s public health agencies.

But as the longtime leader of the anti-vaccine movement scales back immunization guidance and dismisses scientists and advisers, he’s clashed with top medical groups who say he’s not following the science.

The confrontation is deepening confusion among the public that had already surged during the COVID-19 pandemic. Surveys show trust in the agencies Kennedy leads is falling, rather than rising, as the country’s health landscape undergoes dramatic change.
