On September 23 the CDC posted its clinical guidance for this season's COVID vaccine. The guidance recommends the shot for every adult. It also includes a sentence I have never seen on a CDC clinical page, citing "legal uncertainties and inquiries" as the reason the July 2025 schedule remains in effect.

Vaccine recommendations used to come with footnotes about egg allergies. This one comes with a footnote about a lawsuit.

Every adult 18 and older is recommended to get a 2026 to 2027 COVID vaccine. Children 6 months through 17 years with moderate or severe immunocompromise are recommended to get one. Every other child gets one through shared clinical decision making, meaning a conversation with a clinician rather than a default. Immunocompromised people can self attest to that status and be vaccinated wherever vaccines are offered.

This season's shots target the XFG variant and were approved by the FDA on August 27.

ACIP, the committee that normally writes these recommendations, has been without a working quorum since the stay. So the guidance was not voted on by anyone. It was restored by default.

The strangest line in the guidance is a quiet one. The CDC recommends the vaccine for all adults. The FDA label covers adults 65 and older, plus younger people with at least one condition that raises their risk. The CDC acknowledges the gap in plain language. For people under 65 without such a condition, its recommendation "is based on off-label use."

So a healthy 40 year old is recommended by one federal agency to receive a product another federal agency did not approve for them. Both are part of the same department. Neither is wrong on its own terms. Together they tell the public that nobody is in charge.

Children are worse. The CDC says shared decision making for healthy kids. The American Academy of Pediatrics, the plaintiff in the lawsuit, recommends vaccination for all children 6 through 23 months, and for older children at higher risk or whose families want it. A parent asking two authoritative sources gets two answers. (There is also a legal wrinkle. The court blocked the May 2025 directive that created the shared decision language for healthy children, yet the restored July 2025 schedule carries it. The lawyers can sort that out. Parents cannot.)

There are three authors here, and none is neutral. The post that sent me to this came from a pseudonymous account on X, which summarized the CDC page accurately except for one detail (below). The guidance itself comes from a CDC operating under an HHS whose own schedule changes were blocked in court. The competing pediatric recommendation comes from the American Academy of Pediatrics, which is also the lead plaintiff suing the Secretary.

None of that makes anyone wrong. It does mean every source a parent might consult has a stake in the outcome. When the referee is also a party to the lawsuit, the audience stops trusting the call.

The vaccine is the same kind of vaccine it was last year, updated for the current variant the way flu shots are. No new trial overturned anything. What changed is who is allowed to make the recommendation, and that question is now being answered by a federal judge in Boston and an appeals court after that.

My patients on dialysis are not affected by any of this. Kidney failure qualifies on every list, the FDA's included. The people affected are the ones in the middle, healthy adults and parents of young children, who are learning that a public health recommendation can flip with a court filing.

That lesson will outlast the ruling. Once people believe the schedule is politics, every recommendation becomes an opinion, and every opinion has an opposing one.
