The Childhood Vaccine Schedule: Who Counts as an Expert

A committee, a court and a charter

On January 5 the government published a slimmer childhood schedule. "After an exhaustive review of the evidence, we are aligning the U.S. childhood vaccine schedule with international consensus while strengthening transparency and informed consent," Kennedy said. The AAP published its own schedule that month. In a February article in the Denver Gazette, Marianne Goodland reported that "some 20 states" use guidance from the AAP and other medical associations.

Also in January, Children's Health Defense sued the AAP under the federal racketeering law, known as RICO. STAT has described Children's Health Defense as "a vaccine-skeptical group founded by Kennedy." The suit accuses the academy of "a decades-long racketeering scheme to defraud American families about the safety of the childhood vaccine schedule," CIDRAP reported. Its claims are allegations in a complaint.

The AAP and other medical groups had already sued Kennedy over the committee and the schedule. On March 16, Judge Brian Murphy of the federal district court in Massachusetts put on hold the January schedule, the appointments of 13 committee members and every vote the new committee had taken. His central finding was about expertise: "[O]f the fifteen members currently on ACIP, even under the most generous reading, only six appear to have any meaningful experience in vaccines—the very focus of ACIP." In the words of the Congressional Research Service, the changes made after June 11, 2025 "presently have no effect." The federal recommendation is therefore again a birth dose for every newborn. The ruling is preliminary: the judge found the medical groups "likely to succeed," not that they had won. He also wrote that "ACIP as currently constituted cannot meet."

Three days later, the law professor Jonathan Turley replied on his blog. "There are good-faith objections to Kennedy's policy changes," he wrote. "However, the question is who is constitutionally vested with the right to make such decisions."

The committee's charter sets out what its members should know. It was revised in April. In an April 29 article for STAT, Anil Oza reported that the revised charter "added toxicology, pediatric neurodevelopment, and knowledge about 'recovery from serious vaccine injuries' as types of expertise." Children's Health Defense, which has asked to join the case, then argued: "Under the renewed charter, every ACIP member this Court found unqualified or arguably qualified satisfies at least one listed expertise." In the same April 29 report, Oza wrote that the government had filed an appeal. According to Reuters, it challenged only the part of the ruling that blocked the 13 appointees. In a May 11 post for Techdirt, a partisan opinion blog on the left, Timothy Geigner called the new members "nearly all of them virulent anti-vaxxers or otherwise aligned with Kennedy's misinformed views on medicine and science."

On October 6, the federal appeals court in Boston heard the government's appeal. "It's hard to know precisely what harm this relief was designed to address," Chief Judge David Barron said, according to Reuters. The appeals court had not ruled by mid-October.

The disagreement over the core vaccines is narrow. The government's own lawyer told the judge: "So, again, this is not pro- versus anti-vaccine. Both sides here believe in vaccines." A February KFF poll found that "at least 3 in 4 Democrats, independents, Republicans, parents, and MAHA supporters" were confident in the safety of the measles, mumps and rubella (MMR) and polio vaccines. MAHA is the Make America Healthy Again movement associated with Kennedy. The poll's next sentence read: "But fewer are confident in the safety of the vaccines that are no longer universally recommended, and there are larger partisan differences."

Some of what is argued over is settled. Independent reviews "have also rejected any causal relationship between MMR vaccination and autism," the Congressional Research Service wrote in a June report. A separate series of federally commissioned safety reviews, first published in 2011, concluded in 2014 that some vaccines are associated with serious adverse events, but that "these events are extremely rare and must be weighed against the protective benefits that vaccines provide." The same reviews, the Congressional Research Service added, found "cases where there is insufficient evidence to determine whether certain rare adverse health events are linked to vaccines." And the birth dose exists because, as the authors of the recent JAMA study wrote, "Infants infected with HBV in the first year of life have a 90% risk of developing chronic infection." HBV is the hepatitis B virus. The live disputes are whether every newborn needs that dose, which vaccines every child should get, and who decides.

Who counts as a vaccine expert

Judge Murphy measured the new members against the committee's own charter, which calls for "expertise in the use of vaccines and other immunobiologic agents" and similar qualifications. "The Court does not suggest that the other members are not experts in their respective fields," he wrote, "only that the committee as reconstituted is not 'fairly balanced in terms of . . . the functions to be performed.'" In a footnote, he faulted the government for the thin record: "Defendants have provided no basis for the Court to assess how these individual's experiences and qualifications relate to ACIP's functions ..."

That reasoning mostly holds. Federal law requires such committees to be "fairly balanced," and the judge's yardstick was the agency's own written standard. The weak point is the wording. "As to that specific function, the newly appointed members appear distinctly unqualified" is strong language for a record the judge himself calls "incomplete."

In March the judge measured the appointees against the charter's standing language; his ruling notes that "prior versions of the charter contained the same or substantially similar language." In April the charter was revised to add new kinds of expertise, and Children's Health Defense then used it to argue that the people already appointed now qualify. An agency can reasonably want toxicologists on a committee that recommends vaccines for every child. But the judge had found too few members who know vaccines, and a longer list of fields does not add vaccine expertise. A standard rewritten after a measurement, then cited to reverse it, invites one question: would it have read this way before anyone was measured? If the charter is read as Children's Health Defense reads it, the test has been fitted to the answer. Oza's STAT report does not say why the health department revised the charter. The medical groups and the judge relied on wording the charter had carried for years. The Justice Department opposed Children's Health Defense's request to join the case, and the court has not let the group in, Oza reported.

In his blog post, Jonathan Turley answered the finding by pointing to three appointees. One is a transplant surgeon who "has published more than 120 peer-reviewed works and served as principal investigator on NIH transplant biology grants and numerous drug trials." Turley wrote: "That would seem to be someone who could offer unique insights into vaccines and their approval." The second is a professor of operations management with two papers on vaccines. Turley wrote that the judge "brushes aside that stellar academic record." The third is "an epidemiologist with more than two decades of research experience on tuberculosis and infectious diseases and 115 peer reviewed publications."

The judge's test was expertise in vaccines. For the surgeon and the epidemiologist, the ruling found "no evidence in the record" of vaccine work. Turley's reply repeats credentials already in that record. The professor is the close call. The judge did not dispute the vaccine papers. He ruled that "[p]ublishing two papers on a topic, while no doubt relevant to ACIP, likely does not rise to the level of 'expertise' called for under ACIP governing documents." Reasonable readers could draw that line elsewhere. Turley's larger worry is that a judge is choosing the executive branch's advisers. It is the part of the ruling the government chose to appeal.

Turley then turned to the pandemic. "What is most striking is how judges like Murphy showed overwhelming deference to such experts during the COVID-19 period, despite some of those policies later being found not to be based on sound science," he wrote. He concluded: "These same figures were wrong on the science, but now seek to lead another mob to impeach those seeking to change policies and practices at HHS and NIH."

Some pandemic guidance did outrun its evidence, and it is fair to ask whether courts defer consistently. But Turley never shows which of the objectors' positions were wrong, or how pandemic errors bear on whether a vaccine committee needs vaccine experts. The same move works in reverse: an institution that was right about measles is not, for that reason, right about everything.

Counting heads

In January the physician and journalist Céline Gounder took up the question "whose recommendation should I trust?" in her newsletter, Ask Dr. Gounder. "The AAP is not a fringe voice," she wrote. "It represents roughly 67,000 pediatricians and pediatric specialists ... Its 2026 schedule is formally endorsed by 12 major medical organizations ..." On August 10, President Trump signed an executive order calling for revamped childhood vaccine recommendations. Michael Osterholm directs the Vaccine Integrity Project, an independent review of vaccine evidence. In a statement quoted by Jackie Flynn Mogensen of Scientific American, he said: "Parents should continue to rely on the evidence-based immunization recommendations developed by trusted medical and public health experts, including the American Academy of Pediatrics [AAP]." He added that the executive order "does not change the underlying scientific evidence supporting childhood immunization."

The administration counted heads too. The January schedule followed a presidential memorandum and rested on a health department assessment that compared the US schedule with other countries'. According to the Congressional Research Service, the assessment "drew a distinction between 'consensus' vaccines that 20 peer, developed nations also recommend and 'non-consensus' vaccines that not all peer nations recommend." The research service added that "it is not clear how the directive or the assessment defined and identified 'peer, developed nations' or 'peer nations.'"

A count of credentialed bodies inside the field is a reasonable first signal. Gounder goes beyond it: she tells parents to "ask which schedule their child's clinician follows and why." But Gounder does not show that the 12 endorsements from allied societies are 12 separate reviews of the evidence. The AAP is also a plaintiff in the case. Osterholm points to the evidence too. But his advice to rely on "trusted" experts offers little to a parent for whom trust is the thing in dispute.

The government's count fails earlier. Its comparison set is undefined. When every country in a set must agree, the choice of countries decides the answer. Its "consensus" also means agreement among governments, not among scientists.

Lawsuits filed as research

Sayer Ji, a health-freedom advocate who founded the website GreenMedInfo, promoted the racketeering suit in a January Substack post. Under the heading "The Hidden Harms or Overlooked Truths," the post lists claims made "According to the RICO suit and the Stand for Health Freedom complaint," which it describes as a separate suit against the CDC. The list ends: "This is not science. It is bureaucratic dogma enforced through censorship, coercion, and regulatory capture." Under "What the Research Really Says," the first item reads: "CDC internal scientists admitted to destroying data that showed increased autism risk with the MMR vaccine in African-American boys." The post closes: "We are not watching a debate. We are watching a reckoning."

Before any court has ruled, the post gives the AAP, the CDC and the press one verdict: corruption. Claims from complaints appear as "Overlooked Truths" and as "What the Research Really Says," and an undecided allegation of a coordinated scheme becomes the explanation for everything. Hardly Thinking calls that pattern G6: The Hidden Hand: events explained by a concealed actor pulling the strings.

The MMR item accuses identifiable scientists of misconduct. As an accusation, it is unproven. As a statement of what the research says, it points the opposite way from the independent reviews. The post repeats the suit's allegation of "collusion with pharmaceutical giants," which raises a fair question about incentives. The sound response is to allow for the incentive and then still check the claim. The post stops before the second step. A post that distrusts every institution also borrows its authority from one, the courts.

One ruling, three readings

Judge Murphy's ruling describes its own reach: "[T]he Court is not dictating what vaccine-related content Defendants may or may not espouse. Instead, the Court is regulating the procedure by which Defendants do so."

The next day, CIDRAP's newsletter, The State of US Vaccine Policy, told readers: "The administration did not just cut corners; it broke the law." CIDRAP is the center Michael Osterholm directs. Ronald Bailey wrote in Reason, a libertarian magazine, that the judge "struck down several actions undertaken by Health and Human Services (HHS) Secretary Robert F. Kennedy Jr." On March 26 the Federalist, a conservative partisan outlet, ran Ashley Bateman's report under the headline "Judge Rules Parents Have Less Say In Pediatric Vaccine Schedule." She wrote that "The American Academy of Pediatrics (AAP) and other left-wing medical groups sued Kennedy in July," and that the January schedule "aligned the U.S. schedule with most developed nations by removing six vaccinations from the current schedule."

Each outlet overstated the ruling in the direction its audience leans. The judge found that the government had likely broken the law, not that it had. The CIDRAP newsletter half-corrects itself lower down: "This is a preliminary injunction—a temporary hold while the case moves through the courts." A hold pending the case is not a strike-down. The ruling concerns who makes the recommendations and how, not how much say parents have. And the Congressional Research Service wrote: "No vaccines were removed from the childhood immunization schedule." Several were narrowed from every child to some, which is a real change but not a removal.

The case for a targeted dose

Monique Yohanan is a physician and senior fellow at Independent Women, a conservative policy group. In November 2025, before the committee voted, she argued in HIT Consultant, a health-technology trade publication, for giving the birth dose by risk: "in 2025, we have the data, the technology, and the clinical infrastructure to do better." Her rule keeps a safeguard: "If the mother is positive or her status is unknown, the newborn receives hepatitis B immunoglobulin plus vaccine within 12 hours of delivery." Immunoglobulin is a shot of ready-made antibodies. On babies of mothers whose status is unknown, her rule matches the one the CDC adopted in December.

The same standard applies to her. She concedes that "medical records are imperfect, and prenatal results may not always be available at delivery," which is why her safeguard exists. Her case therefore rests on hospitals applying the unknown-status rule every time, and in 1999 they did not. Her description of most newborns as "99% of infants who are not at risk" sits uneasily beside that concession, since a baby whose mother's status is unknown is not known to be safe. Her claim that hospitals today can "do better" is the one the targeted rule depends on, and the 1999 record is the best test of it.

The Pattern Underneath: contested epistemic authority

Most of what anyone believes about medicine comes from someone they trust. The trouble starts when the question of whom to trust is fought over instead of asked. Hardly Thinking calls this pattern G11: Contested Epistemic Authority: a contest over who gets believed, and on what basis, when credentials, experience and institutions point different ways. It fails in two directions.

The first failure treats a credential as if it settled every question near it. It asks for trust where it should show how to check. In this fight it appears among the established institutions and their defenders. Michael Osterholm also points to the evidence, but he asks parents to rely on "trusted" experts when trust is the thing in dispute. Céline Gounder offers 12 allied endorsements as if each were independent. CIDRAP's newsletter leaned on a stronger ruling than the one the judge wrote.

The second failure treats a credential as a reason for suspicion, generalizes from a few expert failures to never deferring, and lets a confident outsider stand in for the specialist. In this fight it appears among the administration's defenders and the distrust movement. Jonathan Turley turns pandemic errors into a reason to discount vaccine expertise. Sayer Ji gives the whole establishment one verdict. The Federalist sorts doctors by politics.

The two poles are not camps. The same actor can stand at both. Children's Health Defense distrusts the medical institutions, yet it leans on a government charter to certify who is qualified. Turley offers credentials from outside vaccines, such as a surgeon's 120 peer-reviewed works, as if they answered a question about vaccine expertise. That is the first failure, and his pandemic argument is the second.

On facts about the vaccines and the schedule, the plainest errors came from the administration's defenders and the distrust movement: the Federalist's "removing six vaccinations" and Sayer Ji's MMR item filed as research. The three overstatements of the ruling came from three different corners. Each was a false statement about a public document, and they count alike. On the question of authority, every camp made a version of the same move, including the camp with the evidence on its side.

The 1999 pause also tests the cynic's view that institutions always cover up. In 2001 the CDC published its own assessment of the pause's effects. It reported that many hospitals in Wisconsin had not reinstated policies to give every newborn the vaccine, and that newborn doses had fallen in Oklahoma and Oregon. Among its findings it listed "that an unvaccinated Michigan infant died from fulminant hepatitis B," a sudden and severe form of the disease. A blanket verdict of cover-up cannot account for that record.

The tools, used and abused

Hardly Thinking's tools are questions a reader can run on any argument, including their own. Each has a fair use and a weaponized one. Two do most of the work here.

C3: The Consensus Audit starts from the fact that everyone defers to someone, and checks the quality of the deference: Are the people agreeing inside the relevant field? How strong is the agreement? Are they independent of one another? Used fairly, it is the question Judge Murphy asked about the committee. As a weapon it runs two ways. One cites a test rewritten after the fact so that the preferred answer passes, as Children's Health Defense did with the revised charter. The other waves a headcount without asking whether the heads are independent, as the medical societies' endorsements and the government's "international consensus" both do.

C5: The Cynicism Firewall separates skepticism from cynicism. Skepticism grades claims one by one; cynicism gives everything from a source the same verdict. Used fairly, it downgrades the claims that failed, such as some pandemic guidance, and keeps crediting the ones that held, such as the evidence on measles. Jonathan Turley's "These same figures" and Sayer Ji's "reckoning" skip the grading. Timothy Geigner of Techdirt skips it too, from the other direction, when he calls the new members "nearly all of them virulent anti-vaxxers."

A reader who ran the Consensus Audit only on the government's "international consensus," or only on the medical societies' endorsements, has used it as a weapon. The fair use starts at home. Take the source you trust most on vaccines and ask: Who exactly agrees on this, are they inside the right field, and what is their record on this kind of question, including the times they changed course? Running a tool on your own side first is a habit HT calls A4: The Mirror Check.

Reader review

Every HT article ends by asking readers to check it against its own rules. The question is not what you think of vaccines but whether this article met the standards it applies to others.

1. Find the passage where this article was hardest on the side you agree with, and the one where it was softest on the side you oppose. Were they judged by the same standard?
2. The article ran C3, the Consensus Audit, on the medical societies' endorsements and on the government's "international consensus." Did it ask the same three questions of both?
3. The article ran C5, the Cynicism Firewall, on Jonathan Turley, Sayer Ji and Timothy Geigner. Run it on the article itself. Does it grade the claims of Children's Health Defense, Sayer Ji and the administration one by one, or does it give everything from them the same verdict? Does it grade the medical societies' claims just as closely?
4. The article opens with the 1999 hepatitis B pause and draws a lesson from it for each camp. Did it use that history evenly, or lean on it against one side?
5. The article says the plainest errors of fact about the vaccines and the schedule came from the administration's defenders and the distrust movement. Do its examples support that, or could a different choice of sources have changed the finding?
6. The article treats Judge Murphy's reasoning as mostly sound while an appeal is pending. Did it give the government's objections enough weight?
7. Choose one quotation and check it against the linked source. Is its context fairly represented? Does the article anywhere attribute a motive to someone, or state an allegation as fact?
