While Kennedy’s announcement was widely discussed on MSNBC and CNN, 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 Speed, to 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 Carlson, the network incessantly promoted misleading and false claims about safe, effective vaccines with the potential to save their viewers’ lives — day after day, month after month, year after year. The network uplifted conspiracy theories, gave airtime to conspiracy theorists and culture war vaccine opponents, demagogued 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 tolls, as The New York Times’ David Leonhardt detailed.
