The federal panel that normally shapes US vaccine recommendations has not met in 2026. CDC lists all three of this year’s Advisory Committee on Immunization Practices (ACIP) meetings as cancelled because of ongoing litigation. An appeals court heard the government’s challenge last month, and as of Nov. 2 we found no reported ruling. Nurses are still giving the vaccines and answering the questions.
What happened
The lawsuit. The American Academy of Pediatrics and other medical groups sued Health Secretary Robert F. Kennedy Jr. and others in federal court in Massachusetts. The challenge includes the secretary’s appointments to ACIP.
March 16, 2026: the order. Judge Brian E. Murphy granted preliminary relief in part. The order stayed a January 2026 memo revising CDC’s childhood immunization schedule. It stayed the appointments of 13 ACIP members named on June 11, 2025, Sept. 11, 2025 and Jan. 13, 2026. And it stayed all votes taken by that panel. Those included votes on thimerosal in flu vaccines (June 2025), COVID-19 vaccine recommendations (September 2025), and hepatitis B vaccination for infants born to mothers who test negative for the virus (December 2025).
The court found the plaintiffs likely to succeed in showing the panel did not meet the “fairly balanced” requirement of the Federal Advisory Committee Act. This is preliminary relief, not a final judgment. The judge also declined to order ACIP not to meet, explaining that a panel missing most of its members could not meet anyway: “ACIP as currently constituted cannot meet.”
The cancellations. CDC’s meeting page, last updated Oct. 9, 2026, shows March 18-19, June 24-26 and Oct. 21-23 each as cancelled due to ongoing litigation. The same page lists February 24-26, 2027 as the next meeting date, with no status note.
Oct. 6, 2026: the appeal. The 1st U.S. Circuit Court of Appeals heard argument. In its opening brief, the government says the order left ACIP without a quorum while also barring the CDC director from changing the schedule without the panel. The brief also says the appeal does not seek to disturb the stay of the January memo or, in the interim, the stay of the votes. News reports of the argument say a Justice Department attorney asked the court to vacate the order on the appointments, and that Chief Judge David Barron questioned why blocking them was justified. The medical groups argued the order does not stop the secretary from naming a new panel that meets legal requirements. Questions from the bench are not a decision.
Oct. 30, 2026: the newest step. CDC published a Federal Register notice seeking nominations for ACIP membership, due by Dec. 31, 2026. CDC provides a slate and the HHS secretary makes the final selection. The notice does not mention the litigation or say when anyone would be seated.
Why it matters at the bedside
ACIP advises the CDC director, who may adopt or reject its recommendations. The court order also notes that Congress wrote ACIP into coverage law, including private insurance coverage, Medicaid and the Vaccines for Children list. So patients and families may ask what the panel’s absence changes for them, and the question often lands on the nurse holding the syringe.
We are deliberately not naming a “current” schedule, because published sources do not line up. Georgetown’s Center for Children and Families wrote in March that the order put the June 2024 childhood schedule back in effect. CDC’s provider schedule page, when we checked it on Nov. 2, showed addenda dated July 2, 2025 and did not mention the order. For flu, CDC’s interim page dated Sept. 1, 2026 says that because of legal uncertainties and inquiries, the flu recommendations from the July 2025 schedule remain in effect for 2026-27. An appeals ruling could also shift any of this.
What guides your practice day to day is your state’s rules, your facility’s policy and the orders you are working under. Some duties do not depend on the panel meeting. Federal law requires a Vaccine Information Statement before each dose of covered vaccines, with the edition date and the date provided noted in the patient’s record. CDC’s best-practice guidance calls for screening for contraindications and precautions before each dose.

This story shows how a recommendation is built. A committee reviews evidence and votes, the CDC director decides whether to adopt the vote, and the result shows up in schedules, coverage rules and, finally, in the orders you carry out. A legal distinction is worth knowing too: a preliminary order holds things in place while a case proceeds, and it can be changed on appeal or at the merits stage.
Do not study from headlines. The 2026 NCLEX-RN test plan puts teaching about preventive care and health maintenance within Health Promotion and Maintenance, at 6% to 12% of the exam. Durable principles carry over to practice. CDC guidance, for example, says people who are severely immunocompromised, and those known to be pregnant, generally should not receive live vaccines. If a class assignment depends on a specific age or dose, use the reference your program assigns and ask your instructor which edition it expects.

- Find your policy. Know where your unit keeps its immunization policy and standing orders.
- Confirm, do not assume. If an order looks out of step with something you read, raise it with your manager, pharmacy, infection prevention team or the prescriber. Do not change it on your own.
- Keep patient answers factual. Refer individual decisions to the prescriber and coverage questions to the payer or the billing team instead of guessing.
- Do the basics every time. Screen, provide the Vaccine Information Statement and document it.
- Watch for the ruling. If anything changes, check your facility and state for updated guidance.
Common questions
Has the appeals court ruled on the ACIP order?
As of Nov. 2, 2026, we found no reported ruling. The 1st U.S. Circuit Court of Appeals heard argument on Oct. 6, 2026. A decision could come at any time and could change the picture.
Did the court ban ACIP from meeting?
The March 16 order declined to enjoin ACIP from meeting. It stayed 13 appointments and said the panel as then constituted could not meet. The parties disagree about what that means in practice for any new panel.
Which immunization schedule should I follow at work?
Follow your facility policy, standing orders and state rules, and confirm with your manager, pharmacy or infection prevention team. We are not naming a schedule here because published sources describe the situation differently and the case is still open.
