Four major U.S. medical groups — the AAP, AAFP, ACOG, and IDSA — jointly released their own recommendations for flu, COVID-19, and RSV vaccines this week. They based them on an independent review from the Vaccine Integrity Project and the American Medical Association. They did it because the CDC still hasn't issued its own fall guidance. The agency only extended last year's flu recommendation, and it's stayed silent on COVID and RSV. It goes back to January, when HHS Secretary Robert F. Kennedy Jr.'s CDC overhauled the childhood vaccine schedule to align with countries like Denmark and Germany. A federal judge blocked much of that overhaul in March, ruling that Kennedy's rebuilt vaccine advisory panel likely broke the law. HHS is now appealing.

1. HHS and the CDC (Robert F. Kennedy Jr.) Say the Old Schedule Asked Too Much

HHS frames the smaller schedule as aligning with international norms and rebuilding trust.

Kennedy says the U.S. was recommending more than it needed to. His CDC's revised schedule now recommends vaccinating against just 11 diseases, down from 18. It's explicitly modeled on schedules in Denmark, Germany, and Japan.

He says the change restores trust and doesn't limit care. Kennedy said the changes were meant to align "the U.S. childhood vaccine schedule with international consensus while strengthening transparency and informed consent." He said the decision "protects children, respects families, and rebuilds trust in public health."

HHS treats outside medical reviewers as part of the problem they're fixing. HHS spokesperson Andrew Nixon called the Vaccine Integrity Project — the group behind this week's independent review — "a self-appointed echo chamber masquerading as oversight" when it launched in April 2025. He said it was "less about integrity and more about salvaging the credibility of a public health bureaucracy that failed millions during the COVID-19 pandemic." HHS hasn't walked that comment back since.

2. The Medical Establishment (AAP, AMA, AAFP, ACOG, IDSA) Says the Federal Process Broke

Doctors say they went around the CDC because the CDC's own process stopped being trustworthy.

The AMA's incoming president says the trust doctors relied on collapsed. Dr. Sandra Adamson Fryhofer, AMA president-elect, said: "For decades, physicians like me have relied on federal vaccine recommendations because they were based on science and careful review. But with the massive changes at the federal level, trust is waning."

AAP kept recommending nearly twice as much as the CDC now does. AAP's 2026 schedule still recommends vaccinating against 18 diseases, versus 11 on the CDC's revised list. Twelve other major medical groups — including the AMA, AAFP, and IDSA — co-signed it.

A federal judge already sided with them once. The AAP sued HHS over the schedule changes and the rebuilt CDC advisory panel. In March, a judge granted a preliminary injunction, ruling that the panel overhaul likely violated federal law and invalidating the votes it had already taken.

3. States Are Left Building Their Own Patchwork, Split by Party

With no single federal standard, red and blue states are answering the question differently.

Most states didn't wait for Washington to sort this out. As of March, 29 states plus D.C. had rejected at least some federal vaccine guidance for kids. Of those, 25 broke from federal guidance across the board and pointed to AAP's schedule instead.

States are splitting almost entirely along party lines. Nearly every state with a Democratic governor has rejected the federal schedule; most Republican-led states have kept it.

Insurers are trying to guarantee coverage continues despite the confusion. The industry group AHIP has pledged that member health plans will keep covering, at no extra cost to patients, any vaccine that was federally recommended as of September 2025 — through the end of 2027. But that promise doesn't cover vaccines the CDC drops later.

Where This Lands

HHS says a narrower, internationally aligned schedule protects families and rebuilds the trust the CDC lost during the pandemic. Doctors say the federal process broke down, so they wrote their own guidance — and they've already beaten HHS once in court. States and insurers are stuck building a patchwork standard in the meantime, split largely by which party runs the statehouse.
