Since Robert F. Kennedy Jr. took over as Health Secretary, he’s been quietly — and sometimes not so quietly — dismantling the vaccine policies that American pediatricians have built and relied on for decades. He fired the entire CDC vaccine advisory committee. He replaced them with his own people. And in January, his department slashed the number of federally recommended childhood vaccines from 17 down to 11 — cutting guidance on flu, rotavirus, hepatitis A, hepatitis B, certain forms of meningitis, and RSV, all in one go.
On Monday, a federal judge said: not so fast.
What the Judge Actually Ruled
U.S. District Judge Brian Murphy in Boston sided with the American Academy of Pediatrics and a coalition of medical groups, ruling that Kennedy’s overhaul of the Advisory Committee on Immunization Practices — the expert panel that shapes the US vaccine schedule — was unlawful. Murphy didn’t mince words. Of the 15 current ACIP members Kennedy had appointed, the judge said most appear “distinctly unqualified.” Only six had any meaningful experience in vaccines or vaccine research, even though the committee’s own charter requires exactly that expertise.
“A committee of non-experts cannot be said to embody fairly balanced points of view within the relevant scientific community,” Murphy wrote.The ruling froze all votes taken by Kennedy’s handpicked committee since June — including the December decision to roll back the hepatitis B vaccine recommendation for newborns. It also forced the postponement of an ACIP meeting that was scheduled for this week. The Trump administration is expected to appeal.
Why This Matters Beyond the Courtroom
Here’s the thing people aren’t saying loudly enough: this isn’t abstract policy. Measles cases in the US have already hit more than 1,300 confirmed cases in 2026 — compared to just 285 in all of 2024. That’s not a coincidence. Vaccine hesitancy has been rising for years, but having the actual Health Secretary publicly casting doubt on the childhood immunization schedule is a different kind of problem. It gives hesitant parents official cover.
Dr. William Schaffner, a professor of medicine at Vanderbilt University, was direct about it: “Vaccines prevent many diseases that used to be the scourge of childhood, causing vast amounts of illness, deaths, and suffering. Maintaining a comprehensive vaccination program is critical, lest we turn back the clock to the bad old days.”
More than 200 organizations, including the American Medical Association, the March of Dimes, and the Autism Science Foundation, had already announced they’d ignore Kennedy’s revised schedule entirely and keep following the original AAP immunization guidelines. The judge’s ruling just gave them legal backing to do so.
What Happens Now
The injunction is temporary — it’s a pause while the broader lawsuit works its way through the courts. Kennedy still leads HHS.
Trump is still behind the push to “align” the US vaccine schedule more closely with other countries, which sounds reasonable until you realize the US schedule accounts for the specific disease burden and healthcare infrastructure of the United States, not Norway or Switzerland.
The AAP called it “a historic and welcome outcome for children, communities, and pediatricians everywhere.” Kennedy’s office hasn’t responded publicly yet, but the administration’s track record suggests this ends up in the appeals court fairly quickly.
For now, the childhood vaccine schedule that existed before Kennedy took over remains in effect. Your pediatrician’s recommendations haven’t changed. But the fight over what goes on that schedule, and who gets to decide, is far from over.
