Report: RFK Jr.’s anti-vaccine agenda curbed as GOP realizes it’s unpopular

Kennedy’s plans were only getting started. The staunch anti-vaccine activist and conspiracy theorist made his most brazen attack on vaccines in January, slashing the CDC’s childhood vaccine schedule from 17 immunizations down to 11 to be in line with recommendations of Denmark, a much smaller country with a relatively homogenous population and universal health care. The US is now an outlier among peer nations for recommending so few childhood vaccines.

Conspiracy theories and political risks

While these and other changes to vaccine recommendations by Kennedy and his underlings have been widely decried by medical and public health experts, they are still not enough for his rabid anti-vaccine followers, who, in no uncertain terms, want all vaccines abolished.

On Monday, the MAHA Institute, a think tank stemming from Kennedy’s Make America Health Again movement, held an event brimming with prominent anti-vaccine activists. Those include Del Bigtree, a prominent conspiracy theorist who leads the anti-vaccine group Informed Consent Action Network, and Mary Holland, who is CEO of the anti-vaccine group Children’s Health Defense, which Kennedy founded.

The event was focused on an alleged “Massive Epidemic of Vaccine Injury,” a nonexistent health crisis the MAHA institute wants to sell to the American public, branded as the catchy term “Mevi.” The six-hour event was essentially an extravaganza of anti-vaccine talking points, with false claims, misinformation, and disinformation about immunizations, including that vaccines cause autism and autoimmune diseases and COVID-19 vaccines are deadly.

At the start of the event, MAHA Institute President Mark Gordon laid out his grand belief that the medical community has orchestrated an elaborate, global, decades-long conspiracy to hide the dangers of vaccines, which he called poisons, and falsify data showing their benefits. “Vaccines are the greatest scam in medical history,” one of his slides proclaimed.

He concluded that “the childhood vaccination schedule needs to be eliminated and all vaccines need to be removed from the market.”

While Gordon and the other speakers were not concerned about the popularity or political ramifications of their beliefs, the Trump administration appears to be. The Post noted that Trump’s top pollster, Tony Fabrizio, has concluded that vaccine skepticism is “rejected by most voters,” and skepticism of vaccine requirements is “politically risky.” His polling data, like many others, have found broad support for vaccines and vaccine requirements. Fabrizio warned in a December memo that politicians supporting eliminating vaccine recommendations “will pay a price in the election.”

Americans trust Fauci over RFK Jr. and career scientists over Trump officials

CDC, confidence, fauci, fda, health, NIH, robert f kennedy jr, scientists, Trust / DJ Henderson / March 6, 2026

Anti-vaccine activist and current Health Secretary Robert F. Kennedy Jr. has worked hard to villainize infectious disease expert Anthony Fauci, even writing a conspiracy-laden book lambasting the former director of the National Institute of Allergy and Infectious Diseases.

But a year into the job as the country’s top health official, Kennedy—who has no background in medicine, science, or public health—still holds less sway with Americans than the esteemed physician-scientist.

In a nationally representative survey conducted in February by the Annenberg Public Policy Center at the University of Pennsylvania, 54 percent of respondents said they had confidence in Fauci, while only 38 percent had confidence in Kennedy. Breaking those supporters down further, 25 percent of respondents said they were “very confident” in Fauci, while only 9 percent said the same for Kennedy.

Overall, the survey found a clear divide between the confidence in Kennedy and other Trump administration officials and that of career scientists and medical associations.

Among federal agencies, 67 percent said they had confidence in career scientists at the Centers for Disease Control and Prevention, the Food and Drug Administration, and the National Institutes of Health. But only 43 percent said they had confidence in the leaders of those agencies.

“The public is differentiating the trustworthiness of career scientists in the CDC, NIH, and FDA from that of the leaders of those agencies and recalling substantially higher confidence in the guidance that former director Fauci provided than that offered by Secretary Kennedy or Dr. Oz,” Ken Winneg, APPC’s managing director of survey research, said in a statement.

RFK Jr.’s anti-vaccine policies are “unreviewable,” DOJ lawyer tells judge

aap, anti-vaccine, health, lawsuit, lawyer, robert f kennedy jr, vaccine / Shannon Garcia / March 5, 2026

US Department of Justice lawyer Isaac Belfer argued that Kennedy has the broad authority to make all of the changes he has already made and more. He claimed that the AAP and other medical groups were asking the court to “supervise vaccine policy indefinitely.”

US District Judge Brian Murphy overseeing the case in Boston appeared skeptical of the suggestion that Kennedy has seemingly limitless authority over federal vaccine policy.

“Is it your position that [Kennedy] is totally unreviewable?” Murphy asked Belfer, according to Reuters. “If the secretary said instead of getting a shot to prevent measles I think you should get a shot that gives you measles, is that unreviewable?”

“Yes,” Belfer replied.

Belfer, arguing on behalf of the Department of Health and Human Services, said the medical organizations were merely seeking to use the courts to enact their favored vaccine policy. But the lawyer for the groups, James Oh, countered that the vaccine policy changes—which were not carried out with typical processes and lack supporting scientific evidence—were done improperly and without reasoned decision-making.

Kennedy’s vaccine policy changes are the “actions of someone who believes he can do whatever he wants,” Oh said, according to Stat News.

Murphy indicated he would issue a ruling on the injunction before the CDC vaccine advisors plan to meet on March 18, calling it a “hard deadline.”

Trump’s MAHA influencer pick for surgeon general goes before Senate

Casey Means, health, MAHA, robert f kennedy jr, Wellness / Mike M. / February 25, 2026

Casey Means, President Trump’s nominee for surgeon general, will appear before the Senate Health Committee on Wednesday and is likely to face scrutiny over her qualifications for becoming the country’s top doctor.

Though Means holds a medical degree from Stanford Medical School, she dropped out of her medical residency and holds no active medical license. Instead, she has pursued a career as a wellness influencer, embracing “functional” medicine, an ill-defined form of alternative medicine. She co-founded a company called Levels, which promotes intensive health tracking, including the use of continuous glucose monitoring for people without diabetes or prediabetes, which is not backed by evidence.

Last year, an analysis by The Washington Post found that Means earned over half a million dollars between 2024 and 2025 from making deals with companies described as selling “diagnostic testing,” “herbal remedies and wellness products,” and “teas, supplements, and elixirs.”

But Means is best known as an ally to anti-vaccine Health Secretary Robert F. Kennedy Jr. and a popular influencer among Kennedy’s Make America Healthy Again (MAHA) followers.

In 2024, Means and her brother Calley Means—also a close Kennedy ally and Trump administration official—wrote a book some consider MAHA’s bible: Good Energy: The Surprising Connection Between Metabolism and Limitless Health. The book provides dietary and lifestyle advice, including a recommendation to avoid processed foods, seed oils, fragrances, a variety of home care products, fluoride, unfiltered water, bananas (when eaten alone), receipt paper, and birth control pills. It includes a chapter titled “Trust Yourself, Not Your Doctor.”

Controversial NIH director now in charge of CDC, too, in RFK Jr. shake-up

anti-vaccine, Bhattacharya, CDC, health, NIH, robert f kennedy jr, vaccine / Kelly Newman / February 20, 2026

Insiders report that, as NIH director, Bhattacharya delegates most of his responsibilities for running the $47 billion agency to two top officials. Instead of a hands-on leader, Bhattacharya has become known for his many public interviews, earning him the nickname “Podcast Jay.”

“Malpractice”

Researchers expect that Bhattacharya will perform similarly at the helm of the CDC. Jenna Norton, an NIH program officer who spoke to the Guardian in her personal capacity, commented that Bhattacharya “won’t actually run the CDC. Just as he doesn’t actually run NIH.” His role for the administration, she added, “is largely as a propagandist.”

Jeremy Berg, former director of the National Institute of General Medical Sciences, echoed the sentiment to the Guardian. “Now, rather than largely ignoring the actual operations of one agency, he can largely ignore the actual operations of two,” he said.

Kayla Hancock, director of Public Health Watch, a nonprofit advocacy group, went further in a public statement, saying, “Jay Bhattacharya has overseen the most chaotic and rudderless era in NIH history, and for RFK Jr. to give him even more responsibility at the CDC is malpractice against the public health.”

Like other commenters, Hancock noted his apparent lack of involvement at the NIH and put it in the context of the current state of US public health. “This is the last person who should be overseeing the CDC at a time when preventable diseases like measles are roaring back under RFK Jr.’s deadly anti-vax agenda,” she said.

It is widely expected that Bhattacharya will, like O’Neill, act as a rubber-stamp for Kennedy’s relentless anti-vaccine agenda items. When Kennedy dramatically overhauled the CDC’s childhood vaccine schedule, slashing recommended vaccinations from 17 to 11 without scientific evidence, Bhattacharya was among the officials who signed off on the unprecedented change.

Ultimately, Bhattacharya will only be in the role for a short time, at least officially. The role of CDC director became a Senate-confirmed position in 2023, and, as such, an acting director can serve only 210 days from the date the role became vacant. That deadline comes up on March 25. President Trump has not nominated anyone to fill the director role.

FDA reverses surprise rejection of Moderna’s mRNA flu vaccine

anti-vaccine, fda, health, moderna, robert f kennedy jr, vinay prasad / Beth Washington / February 18, 2026

Anti-vaccine agenda

Agency insiders told reporters that a team of career scientists was ready to review the vaccine and held an hourlong meeting with Prasad to present the reasons for moving forward with the review. David Kaslow, a top career official responsible for reviewing vaccines, also wrote a memo detailing why the review should proceed. Prasad rejected the vaccine application anyway.

According to today’s announcement, the FDA reversed that rejection when Moderna proposed splitting the application, seeking full approval for the vaccine’s use in people aged 50 to 64 and an accelerated approval for use in people 65 and up. That latter regulatory pathway means Moderna will have to conduct an additional trial in that age group to confirm its effectiveness after it’s on the market.

Andrew Nixon, spokesperson for the US Department of Health and Human Services, confirmed the reversal to Ars Technica. “Discussions with the company led to a revised regulatory approach and an amended application, which FDA accepted,” Nixon said in a statement. “FDA will maintain its high standards during review and potential licensure stages as it does with all products.”

The FDA typically takes a levelheaded approach to working with companies, rarely making surprising decisions or rejecting applications outright. While Prasad claimed the rejection was due to the control vaccine, the move aligns with Health Secretary Robert F. Kennedy Jr.’s broader anti-vaccine agenda.

Kennedy and the allies he has installed in federal positions are particularly hostile to mRNA technology. Moderna has already lost more than $700 million in federal contracts to develop pandemic vaccines. Next month, Kennedy’s MAHA Institute is hosting an anti-vaccine event that alleges there’s a “massive epidemic of vaccine injury.” The event description claims without evidence that use of mRNA vaccines is linked to “rising rates of acute and chronic illness.”

Vaccine makers and industry investors, meanwhile, are reporting that Kennedy’s relentless anti-vaccine efforts are chilling the entire industry, with companies abandoning research and cutting jobs. In comments to The New York Times, Moderna’s president, Stephen Hoge, said, “There will be less invention, investment, and innovation in vaccines generally, across all the companies.”

Dewormer ivermectin as cancer cure? RFK Jr.’s NIH funds “absurd” study.

cancer, health, ivermectin, NCI, NIH, robert f kennedy jr / Shannon Garcia / February 10, 2026

The National Cancer Institute is using federal funds to study whether cancer can be cured by ivermectin, a cheap, off-patent anti-parasitic and deworming drug that fringe medical groups falsely claimed could treat COVID-19 during the pandemic and have since touted as a cure-all.

Large, high-quality clinical trials have resoundingly concluded that ivermectin is not effective against COVID-19. And there is no old or new scientific evidence to support a hypothesis that ivermectin can cure cancer—or justify any such federal expenditure. But, under anti-vaccine Health Secretary Robert F. Kennedy Jr.—who is otherwise well-known for claiming to have a parasitic worm in his brain—numerous members of the medical fringe are now in powerful federal positions or otherwise hold sway with the administration.

During a January 30 event, Anthony Letai, a cancer researcher the Trump administration installed as the director of the NCI in September, said the NCI was pursuing ivermectin.

“There are enough reports of it, enough interest in it, that we actually did—ivermectin, in particular—did engage in sort of a better preclinical study of its properties and its ability to kill cancer cells and we’ll probably have those results in a few months. So we are taking it seriously.”

The comments were highlighted today in a report from KFF Health News. Ars Technica was also at the event, “Reclaiming Science: The People’s NIH,” which was hosted by the MAHA [Make America Healthy Again] Institute. In the rest of his comments, Letai seemed to make a noticeable effort to temper expectations while also trying to avoid offending any ivermectin believers. “It’s not going to be a cure-all for cancer,” he said. At another point, he said that even if there are signals of anti-cancer properties in the preclinical studies, “I can tell you again, it’s not a really strong signal.”

Doctors face-palm as RFK Jr.’s top vaccine advisor questions need for polio shot

He then pondered out loud what would happen if people stopped getting vaccinated. “If we take away all of the herd immunity, then does that switch, does that teeter-totter switch in a different direction?” he asked.

Backlash

In a statement, AMA Trustee Sandra Adamson Fryhofer blasted the question. “This is not a theoretical debate—it is a dangerous step backward,” she said. “Vaccines have saved millions of lives and virtually eliminated devastating diseases like polio in the United States. There is no cure for polio. When vaccination rates fall, paralysis, lifelong disability, and death return. The science on this is settled.”

Fryhofer also took aim at Milhoan’s repeated argument that the focus of vaccination policy should move from population-level health to individual autonomy. Moving away from routine immunizations, which include discussions between clinicians and patients, “does not increase freedom—it increases suffering,” she said, adding that the weakening of recommendations “will cost lives.”

Overall, Milhoan’s comments only further erode the relevance of ACIP and federal vaccine policy among the medical community and states. According to a KFF policy brief, 27 states and Washington, DC, have already announced they will not follow current CDC vaccine recommendations, which Kennedy dramatically overhauled earlier this month without even consulting the ACIP. Instead, the majority of states are relying on previous recommendations or recommendations made within states or by medical organizations.

On Monday, the American Academy of Pediatrics announced the 2026 update to its childhood and adolescent vaccine schedule, which it has held up as an alternative to the CDC’s schedule and has been widely embraced by pediatricians. In the announcement, AAP noted that 12 other medical organizations have endorsed the schedule, including the AMA, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the Infectious Diseases Society of America, and the Pediatric Infectious Diseases Society.

The AAP’s updated recommendations are largely the same as the schedule from last year, but it is significantly different from the CDC’s recommendations, which “depart from longstanding medical evidence and no longer offer the optimal way to prevent illnesses in children,” the AAP said.

“The AAP will continue to provide recommendations for immunizations that are rooted in science and are in the best interest of the health of infants, children and adolescents of this country,” AAP President Andrew Racine said in the announcement.

Under anti-vaccine RFK Jr., CDC slashes childhood vaccine schedule

anti-vaccine, health, robert f kennedy jr, Science, vaccine / Shannon Garcia / January 5, 2026

Under anti-vaccine Health Secretary Robert F. Kennedy Jr., federal health officials on Monday announced a sweeping and unprecedented overhaul of federal vaccine recommendations, abruptly paring down recommended immunizations for children from 17 to 11.

Officials claimed the rationale for the change was to align US vaccine recommendations more closely with those of other high-income countries, namely Denmark, a small, far less diverse country of around 6 million people (smaller than the population of New York City) that has universal health care. The officials also claim the change is necessary to address the decline in public trust in vaccinations, which has been driven by anti-vaccine activists, including Kennedy.

“This decision protects children, respects families, and rebuilds trust in public health,” Kennedy said in a statement.

Health experts disagree. “Kennedy’s decision will harm and kill children, like all of his anti-vaccination decisions will,” virologist James Alwine, who works with the organization Defend Public Health, said in a statement.

The American Academy of Pediatrics, a vocal critic of Kennedy, blasted the changes, saying “to arbitrarily stop recommending numerous routine childhood immunizations is dangerous and unnecessary,” AAP President Andrew Racine said. “The United States is not Denmark,” he added.

Under the new federal recommendations, universally recommended immunizations are pared down to these 11 diseases: measles, mumps, rubella, polio, pertussis (whooping cough), tetanus, diphtheria, Haemophilus influenzae type B (Hib), pneumococcal disease, human papillomavirus (HPV), and varicella (chickenpox).

Impeachment articles filed against RFK Jr., claiming abuse of power

anti-vaccine, Haley Stevens, health, impeachment, misinformation, robert f kennedy jr / Shannon Garcia / December 10, 2025

“Reckless”

Stevens’ impeachment articles were directly supported by a grassroots political organization advocating for the country’s scientific community, called Stand Up for Science.

Colette Delawalla, the group’s founder and CEO, was quoted in Stevens’ press announcement, saying Kennedy’s actions are “negligent and will result in harm and loss of life. He must be impeached and removed.”

In the 13-page impeachment articles filed, Stevens accuses Kennedy of high crimes and misdemeanors, citing a lengthy list of actions Kennedy has taken that have been widely decried by public health, scientific, and medical experts as harmful. Those include gutting funding for research, including cancer, addiction, and mRNA vaccine technology; making the work of the US Department of Health and Human Services less transparent by ending public comment periods for some actions; making false and misleading health statements, particularly about vaccines; firing the entire panel of vaccine advisors for the Centers for Disease Control and Prevention; hiring a slew of his fellow anti-vaccine activists to undermine public health from within the health department in roles for which they are unqualified; and making unilateral changes to federal vaccine recommendations.

“Under his watch, families are less safe and less healthy, people are paying more for care, lifesaving research has been gutted, and vaccines have been restricted,” Stevens said. “His actions are reckless, his leadership is harmful, and his tenure has become a direct threat to our nation’s health and security.”

CDC vaccine panel realizes again it has no idea what it’s doing, delays big vote

anti-vaccine, CDC, health, robert f kennedy jr / Beth Washington / December 6, 2025

Today’s meeting was chaotic and included garbage anti-vaccine presentations.

The panel of federal vaccine advisors hand-selected by anti-vaccine Health Secretary Robert F. Kennedy Jr. has once again punted on whether to strip recommendations for hepatitis B vaccinations for newborns—a move it tried to make in September before realizing it didn’t know what it was doing. The decision to delay the vote today came abruptly this afternoon when the panel realized it still does not understand the topic or what it was voting on.

Prior to today’s 6–3 vote to delay a decision, there was a swirl of confusion over the wording of what a new recommendation would be. Panel members had gotten three different versions of the proposed recommendation in the 72 hours prior to the meeting, one panelist said. And the meeting’s data presentations this morning offered no clarity on the subject—they were delivered entirely by anti-vaccine activists who have no subject matter expertise and who made a dizzying amount of false and absurd claims.

“Completely inappropriate”

Overall, the meeting was disorganized and farcical. Kennedy’s panel has abandoned the evidence-based framework for setting vaccine policy in favor of airing unvetted presentations with misrepresentations, conspiracy theories, and cherry-picked studies. At times, there were tense exchanges, chaos, confusion, and misunderstandings.

Still, the discussion was watched closely by the medical and health community, which expects that the panel—composed of Kennedy allies who espouse anti-vaccine views—will strip the recommendation for a hepatitis B vaccine birth dose. Decisions by the committee, the Advisory Committee on Immunization Practices (ACIP) in the Centers for Disease Control and Prevention, have historically set national vaccine policy. Health insurance programs are required to cover, at no cost, vaccinations recommended by the ACIP. So rescinding a recommendation means Americans could lose coverage.

Medical and public health experts consider the birth-dose vaccination to be critical for protecting all infants from contracting the highly infectious virus that, when acquired early in life from their mother or anyone else, almost always causes chronic infections that lead to liver disease, cancer, and early death. There is no data suggesting harms from the newborn dose, nor any safety data suggesting that delaying the first dose by a month or two, as ACIP is considering, would be safer or better in any way. But studies do indicate that such a delay would lead to more hepatitis B infections in babies

These points were hard to find in today’s presentations. Abandoning standard protocol, the meeting did not include any presentations or data reviews led by CDC scientists or subject matter experts. Kennedy has also barred medical and health expert liaisons—such as the American Medical Association, the Infectious Disease Society of America, and the American Academy of Pediatrics—from participating in the ACIP working groups, which compile data and set language for proposed vaccine recommendations.

Anti-vaccine presentations

Instead, today, ACIP heard only from anti-vaccine activists. The first was Cynthia Nevison, a climate researcher and anti-vaccine activist with ties to Children’s Health Defense, Kennedy’s anti-vaccine organization. She was also a board member of an advocacy group called Safe Minds, which promotes a false link between autism and vaccines, specifically the mercury-containing vaccine preservative thimerosal, which was removed from routine childhood vaccines in the early 2000s. (Safe Minds stands for Sensible Action For Ending Mercury-Induced Neurological Disorders.) According to her academic research profile at the University of Colorado Boulder, her expertise is in “global biogeochemical cycles of carbon and nitrogen and their impact on atmospheric trace gases.”

Far from that topic, Nevison gave a presentation downplaying the transmission of hepatitis B and the benefits of vaccines. She falsely claimed that the dramatic decline in hepatitis B infections that followed vaccination efforts was not actually due to the vaccination efforts—despite irrefutable evidence that it was. And she followed that up with her own unvetted modeling claiming that CDC scientists overestimate the risk of transmission. She ended by presenting a few studies showing declines in blood antibody levels after initial vaccination, which she claimed suggests that the hepatitis B vaccine does not offer lifelong protection, an incorrect takeaway based on her lack of expertise.

The author of one of the studies just happened to be present at today’s meeting. Pediatrician Amy Middleman, who is an ACIP liaison representing the Society for Adolescent Health and Medicine (SAHM) and a professor at Case Western Reserve University School of Medicine, was the first author on a key study Nevison referenced. Middleman was quick to point out that Nevison had completely misunderstood the study, which actually showed that cell-based immune protection from the vaccine offers robust lifelong protection, even after initial antibody levels decline (called an anamnestic response).

“This is where a really experienced understanding of immunization comes into play,” Middleman said. “The entire point of our study is that for most vaccines, the anamnestic response is really their superpower. So this study showed that memory cells exist such that when they see something that looks like the hepatitis B disease, they actually attack. The presence of a robust and anamnestic response, regardless of circulating antibody years later, shows true protection.”

The next presentation was from Mark Blaxill, an anti-vaccine activist installed at the CDC in September. Blaxill gave a presentation on hepatitis B vaccine safety, despite having no background in medicine or science. He previously worked as an executive for a technology investment firm and, like Nevison, also worked for Safe Minds, where he was vice president. Blaxill has written books and many articles falsely claiming that vaccines cause a variety of harms in children. In 2004, when an Institute of Medicine analysis concluded that there were no convincing links between vaccines and autism, Blaxill publicly protested the result.

In his presentation, he attacked the quality of safety data in past hepatitis B studies. Though he stopped short of suggesting any specific harms from the vaccine, he aired unsubstantiated possibilities popular with anti-vaccine activists. He also noted a study finding that some babies had fatigue and irritability after vaccination, which he bizarrely suggested was a sign of encephalitis (inflammation of the brain).

Real-time feedback

Cody Meissner, a pediatrician and voting member of ACIP who is the most qualified and experienced member of the panel, quickly called out the suggestion as ridiculous. “That is absolutely not encephalitis,” Meissner said with frustration in his voice. “That’s not a statement that a physician would make. [Those symptoms] are not related to encephalitis, and you can’t say that.”

As in previous meetings, Jason Goldman, the ACIP liaison representing the American College of Physicians, gave the most biting response to the meeting overall, saying:

Once again, this committee fails to use the evidence to recommend framework and shows absolutely no understanding of the process or the gravity of the moment of the recommendations that you make. We need to look at all the evidence and data and not cherry-pick them… This meeting is completely inappropriate for an administration that wants to avoid fraud, waste, and abuse. You are wasting taxpayer dollars by not having scientific, rigorous discussion on issues that truly matter. The best thing you can do is adjourn the meeting and discuss vaccine issues that actually need to be taken up… As physicians, your ethical obligation is primum non nocere, first do no harm, and you are failing in that by promoting this anti-vaccine agenda without the data and evidence necessary to make those informed decisions.

The panel will reconvene tomorrow for an all-day meeting in which the members will consider a vote on the hepatitis B vaccine for a third time. The meeting will also host other anti-vaccine presentations attacking the childhood vaccine schedule in its entirety.

Without evidence, RFK Jr.’s vaccine panel tosses hep B vaccine recommendation

ACIP, anti-vaccine, CDC, health, hepatitis B, robert f kennedy jr / 9u50fv / December 5, 2025

Retsef Levi, an operations management expert and ACIP member who expressed strong anti-vaccine views, said, “I think that the intention behind this [recommendation change is] that parents should carefully think about whether they want to take the risk of giving another vaccine to their child, and many of them might decide that they want to wait far more than two months, maybe years and maybe up to adulthood.”

In the discussion before the vote, Meissner described the motivation as “baseless skepticism.”

With a second vote, the panel created a new recommendation that parents and health care providers should consider testing a child’s antibody levels after each dose of the three-dose hepatitis B series. The recommendation suggests that if a baby’s antibody levels reach a certain threshold, they can forgo completing the series.

CDC subject matter experts, medical organizations, and members of the committee pointed out that there is no data to support this recommendation. Vaccine efficacy data is based on the entire three-dose series, and antibody levels are not sufficient to presume the same level of lifelong protection.

This vote “is kind of making things up,” Meissner said in frustration. “I mean, it’s like Never Never Land.”

There was no data or discussion on the administrative burden or clinical feasibility of testing the antibody levels of a baby after each dose.

The panel approved the recommendation on antibody testing in a vote of 6–4, with one abstention.

Medical experts were quick to condemn today’s votes. Sandra Adamson Fryhofer, a board member of the American Medical Association, said the vote is “reckless and undermines decades of public confidence in a proven, lifesaving vaccine.”

“Today’s action is not based on scientific evidence, disregards data supporting the effectiveness of the Hepatitis B vaccine, and creates confusion for parents about how best to protect their newborns,” Fryhofer said in a statement.
