NEW YORK — President-elect Donald Trump says he will nominate anti-vaccine activist Robert F. Kennedy Jr. to lead the Department of Health and Human Services, putting a man whose views public health officials have decried as dangerous in charge of a massive agency that oversees everything from drug, vaccine and food safety to medical research and the social safety net programs Medicare and Medicaid.

“For too long, Americans have been crushed by the industrial food complex and drug companies who have engaged in deception, misinformation, and disinformation when it comes to Public Health,” Trump said Thursday in a post on his Truth Social site announcing the appointment. Kennedy, he said, would “end the Chronic Disease epidemic” and “Make America Great and Healthy Again!”

Kennedy is one of the most prominent anti-vaccine activists in the world and has long advanced the debunked idea that vaccines cause autism and other health issues.

Hailing from one of the nation’s most storied political families, Kennedy is the son of the late Attorney General Robert F. Kennedy and the nephew of President John F. Kennedy. He first challenged President Joe Biden for the Democratic nomination last year. He then ran as an independent before abandoning his bid after striking a deal to give Trump his endorsement with a promise to have a role overseeing health policy in a second Trump administration.

He and the president-elect have since become good friends. The two campaigned together extensively during the race’s final stretch, and Trump had made clear he intended to give Kennedy a major role overseeing public health as part of a campaign to “Make America Healthy Again.”

“I’m going to let him go wild on health,” Trump said at a rally last month.

During his victory speech in Palm Beach, Florida, last week, Trump exclaimed, “Go have a good time, Bobby!”

Still, it was unclear precisely what job he would be offered. In an October interview on CNN, Trump transition co-chair Howard Lutnick assured there was no way Kennedy would receive the job he got.

The appointment drew alarms from public health experts.

“Robert F. Kennedy, Jr., is not remotely qualified for the role and should be nowhere near the science-based agencies that safeguard our nutrition, food safety, and health,” said Dr. Peter Lurie, president of the public health watchdog group Center for Science in the Public Interest.

Dr. Mandy Cohen, director of the Centers for Disease Control and Prevention, told The Associated Press, “I don’t want to go backwards and see children or adults suffer or lose their lives to remind us that vaccines work, and so I am concerned.”

“Any misinformation coming from places of influence, of power, are concerning,” she said.

During the campaign, Kennedy told NewsNation that Trump had asked him to “reorganize” agencies including the CDC, the National Institutes of Health and the Food and Drug Administration.

Kennedy has pushed against processed foods and the use of herbicides like Roundup weed killer. He has long criticized the large commercial farms and animal feeding operations that dominate the industry.

But he is perhaps best known for his criticism of childhood vaccines.

Again and again, Kennedy has made his opposition to vaccines clear. In July, he said in a podcast interview that “There’s no vaccine that is safe and effective” and told FOX News that he still believes in the long-ago debunked idea that vaccines can cause autism.

In a 2021 podcast he urged people to “resist” CDC guidelines that advise when kids should receive routine vaccinations.

“I see somebody on a hiking trail carrying a little baby and I say to him, ‘Better not get them vaccinated,'” Kennedy said.

Repeated scientific studies in the U.S. and abroad have found no link between vaccines and autism. Vaccines have been proven safe and effective in laboratory testing and in real world use in hundreds of millions of people over decades. The World Health Organization credits childhood vaccines with preventing as many as 5 million deaths a year

Trump during his first term launched Operation Warp Speed, an effort to speed the production and distribution of a vaccine to combat COVID-19. The resulting vaccines were widely credited, including by Trump himself, with saving many lives.

Trump, in his announcement, said that, under Kennedy, HHS would “play a big role in helping ensure that everybody will be protected from harmful chemicals, pollutants, pesticides, pharmaceutical products, and food additives that have contributed to the overwhelming Health Crisis in this Country.” But HHS does not have jurisdiction over many of those issues, which fall under the purview of the Environmental Protection Agency and Department of Agriculture.

Kennedy is an attorney who has built a loyal following over several decades of people who admire his lawsuits against major pesticide and pharmaceutical companies. He has pushed for tighter regulations around the ingredients in foods.

With the Trump campaign, he worked to shore up support among young mothers in particular, with his message of making food more healthful in the U.S., promising to model regulations after those imposed in Europe. In a nod to Trump’s original campaign slogan, he named the effort “Make America Healthy Again.”
