Seven years after Americans celebrated the licensing of Jonas Salk’s polio vaccine, President John F. Kennedy called on Congress to finance a nationwide vaccination program to stamp out what he called the “ancient enemies of our children”: infectious disease.
Now Kennedy’s nephew, Robert F. Kennedy Jr., is the nation’s chief critic of vaccines — a public health intervention that has saved millions of lives — and President-elect Donald J. Trump’s pick to become the next secretary of health and human services. Mr. Kennedy calls himself a vaccine safety activist. The press calls him a vaccine skeptic. His detractors call him an anti-vaxxer and a conspiracy theorist.
Whatever one calls him, Mr. Kennedy is a polarizing choice whose views on certain public health matters beyond vaccination are far outside the mainstream. He opposes fluoride in water. He favors raw milk, which the Food and Drug Administration deems risky. And he has promoted unproven therapies like hydroxychloroquine for Covid-19. His own relatives called his presidential bid “dangerous for our country.”
If there is a through line to Mr. Kennedy’s thinking, it appears to be a deep mistrust of corporate influence on health and medicine. In some cases, that has led him to support positions that are also embraced by public health professionals, including his push to get ultra-processed foods, which have been linked to obesity, off grocery store shelves. His disdain for profit-seeking pharmaceutical manufacturers and food companies drew applause on the campaign trail.
People close to him say his commitment to “make America healthy again” is heartfelt.
“This is his life’s mission,” said Brian Festa, a founder of We the Patriots U.S.A., a “medical freedom” group that has pushed back on vaccine mandates, who said he has known Mr. Kennedy for years.
But like Mr. Trump, Mr. Kennedy also has a tendency to float wild theories based on scanty evidence. And he has hinted at taking actions, like prosecuting leading medical journals, that have unnerved the medical community. On Friday, many leading public health experts reacted to his nomination with alarm.
