Fox News hosts elevated Robert F. Kennedy Jr. to help return President Donald Trump to the White House. They then greased the skids for Kennedy’s confirmation as secretary of health and human services. But as he works to demolish American health care researchthey are nowhere to be found.

Kennedy, a prominent vaccine skeptic who once described Covid-19 shots as “the deadliest vaccine ever made,” announced on Tuesday that he is terminating nearly $500 million in federal contracts supporting the development of next-generation vaccines and other treatments based on mRNA technology. “After reviewing the science and consulting top experts at NIH and FDA, HHS has determined that mRNA technology poses more risks than benefits for these respiratory viruses,” he said in a video posted online.

Before the pandemic, Kennedy was not a natural fit for the Fox audience.

But Kennedy’s announcement drew harsh criticism from infectious disease experts and other scientists. They warned that the cuts could stall treatments for everything from respiratory illnesses to cancer, leave the nation more exposed to pandemics, undermine public trust in vaccines and threaten U.S. global leadership in medical advances.

While Kennedy’s announcement was widely discussed on BLN and BLN, as well as by national broadcast, print and digital outlets, Fox News has almost entirely ignored it. A single 30-second news brief on its “Special Report” program represents the entirety of the Trumpist propaganda network’s coverage through Thursday, according to a Media Matters review.

Fox News may not want to claim credit for Kennedy as he stifles crucial medical research, but it certainly deserves it. You can’t explain the evolution from Trump’s first administration, which fast-tracked the development of mRNA vaccines for Covid-19 through Operation Warp Speedto the second term’s anti-vax, “Make America Healthy Again” schtick without talking about the network’s role in turning the GOP base against vaccines and toward conspiracy theorists like Kennedy.

When pharmaceutical companies began rolling out the vaccines produced under the Trump administration in late 2020 and early 2021, Fox News’ stars could have used the unique influence they have over their viewers to encourage them to get their Covid-19 shots. But Trump had lost his re-election bid, and the network that had worked so hard to keep him in office instead pandered to anti-vaxxers by turning against the vaccination campaign helmed by his successor, President Joe Biden.

Led by its then-prime-time star Tucker Carlsonthe network incessantly promoted misleading and false claims about safe, effective vaccines with the potential to save their viewers’ lives — day after day, month after monthyear after year. The network uplifted conspiracy theoriesgave airtime to conspiracy theorists and culture war vaccine opponentsdemagogued against efforts to get more people to receive these lifesaving shots, and propped up ineffective cures as potential substitutes. Fox News continued to broadcast these segments even as more Republican parts of the country, with lower vaccination rates, suffered higher Covid-19 death tollsas The New York Times’ David Leonhardt detailed.

All of the fawning attention on Kennedy from the right had the impact one would expect.

Before the pandemic, Kennedy, the scion of a Democratic dynasty who once called for a boycott of Fox News host Sean Hannity and described him as a fascist, was not a natural fit for the Fox audience. But with the Covid-19 vaccine campaign underway, his decades of work undermining vaccines and his attacks on the new mRNA vaccines in particular suddenly made him attractive to the right.

When he began his presidential campaign in March 2023 — with Carlson’s show as his launchpad — MAGA media stalwarts saw an opportunity. They treated Kennedy’s bid, first in the Democratic primary and then as an independent candidate, as a potent spoiler candidacy to boost Trump’s return to power. Kennedy became a constant presence on the programs of pro-Trump commentators. Fox provided him with more airtime than many would-be Republican standard-bearers received.

All of the fawning attention on Kennedy from the right — alongside mainstream news coverage of his bizarre history, such as his claim that a parasite in his brain had triggered memory loss — had the impact one would expect: Kennedy became more popular with Republicans than Democrats. As polls increasingly showed that he was pulling support from Trump, though, MAGA media figures like Hannity abruptly turned on Kennedy. After Carlson reportedly helped to facilitate Kennedy’s decision to drop out and endorse the once-and-future president, Fox hosts resumed showering the anti-vax champion with praise.

As Election Day approached, talk turned to what reward Kennedy could expect in return. Paul Dans, the former head of Project 2025, floated Kennedy’s name for HHS secretary — and that’s precisely the position Trump nominated him for.

Not everyone on the right was willing to accept Kennedy’s ascent. The editorial boards of Rupert Murdoch’s Wall Street Journal and New York Post denounced the decision and called for Senate Republicans to vote down his nomination.

Murdoch’s print voices lost out to his cable news shouters.

But Fox News hosts were elated. As Kennedy’s nomination moved through the Senate, they touted him as a “reformer” and “true health care crusader” who had “the skills, knowledge, and experience” needed for the job.” When Kennedy said he wasn’t going to take away anyone’s vaccines, Fox said he wasn’t going to take away anyone’s vaccines.

Murdoch’s print voices lost out to his cable news shouters — the Senate confirmed Kennedy on a near-party-line vote, with Sen. Mitch McConnell, a polio survivor, the sole Republican vote against him.

And lo and behold, once confirmed, Kennedy continued the anti-vax project to which he had dedicated years of his life. He yanked $2 billion in funding to vaccinate children whose families may not be able to afford immunizations. He downplayed the importance of vaccination for quelling a measles outbreak even as measles cases hit record highs. He replaced the members of a vaccine advisory board with his own picks — some of whom were notorious vaccine critics — who plan to review the childhood vaccination schedule and scrutinize its components. And now he’s terminated federal funding that could have fueled a new wave of cures.

Under Kennedy’s leadership, the Department of Health and Human Services itself has become a grave threat to public health. That is the regrettable but inevitable consequence of Fox News’ cynical exploitation of its viewers. The network’s hosts should take a bow — they earned it.
