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

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.”

WHO slams US-funded newborn vaccine trial as “unethical”

anti-vaccine, CDC, health, hepatitis B, Robert F Kenned Jr., WHO / 9u50fv / February 14, 2026

“Exploiting scarcity is not ethical,” the WHO wrote in its statement today.

Dangerous trial

The United Nations health agency highlighted that the hepatitis B vaccine birth dose is “an effective, and essential public health intervention” that has “been used for over three decades, with more than 115 countries including it in their national schedules. “

“It prevents life‑threatening liver disease by stopping mother‑to‑child transmission at birth,” the WHO wrote, noting that more than 12 percent of adults in Guinea-Bissau have chronic hepatitis B.

In a section subtitled “Why withholding the vaccine is unethical,” the WHO lays out all the reasons the trial is dangerous.

“From what is publicly described, the [trial] protocol does not appear to ensure even a minimum level of harm reduction and benefit to the study participants (e.g., screening pregnant women and vaccinating newborns exposed to hepatitis B),” the WHO wrote.

As a proven lifesaving vaccine, withholding it from some study participants would expose newborns to serious and potentially irreversible harm, including chronic infection, cirrhosis, and liver cancer, the WHO argues. There is no scientific justification for withholding a proven intervention, and there is no credible evidence of the safety concerns that Benn and her colleagues claim to be looking for in their trial. The WHO also noted that the publicly available information about the trial indicates that it will be a single-blind, no-treatment-controlled design, which “raises a significant likelihood of substantial risk of bias, limiting interpretability of the study results and their policy relevance.”

As of now, the trial appears to be suspended. Nature News reported that in a January 22 press conference, health officials in Guinea-Bissau said that a technical and ethical review was pending. “There has been no sufficient coordination in order to take a final decision regarding the study,” Quinhin Nantote, the minister of public health for Guinea-Bissau, said. “Faced with this situation, we decided to suspend it.”

Previously, the Africa Centres for Disease Control and Prevention suggested that the trial would not go forward. However, the US Department of Health and Human Services provided a statement saying that it was “proceeding as planned.”

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.

Big Pharma is openly railing against RFK Jr.’s anti-vaccine agenda

anti-vaccine, health, pharmaceutical, Robert F Kenned Jr. / Mike M. / January 15, 2026

Waiting for the midterms

But pharmaceutical executives don’t appear comforted by the pushback. “Today it may be childhood vaccines or mRNA, but tomorrow it’s everything,” Noubar Afeyan, co-founder and chairman of Moderna, maker of mRNA vaccines, said. “We have to say not just ‘why is this happening?,’ but ‘Where will it stop?’”

As a bad flu season is underway, Dean Li, president of Merck Research Laboratories, noted that the anti-vaccine rhetoric is hitting seasonal flu shots. “With the pressure on vaccination, I cannot foresee flu vaccination increasing in this country over the next three years,” he said in a presentation.

Sanofi Chief Executive Paul Hudson had a similarly pessimistic outlook. “It’s clear this administration has a particular sensitivity around vaccination, and indeed pediatric vaccination,” Hudson said. “I’m asked all the time ‘what are you going to do to fix this?,’ and the truth is we just need to stay extremely objective and continue presenting the evidence. There’s really very little else we can do,” except wait for the midterm elections, he said.

“We will have to maintain a steely focus on the long-term future of vaccines and deal with any uncertainty around vaccine coverage rates in the short-term based on misinformation, Facebook posts, and statements from the top,” he said.

Bourla also worried about the conditions Kennedy is creating to attack drug makers. Kennedy, who is an environmental lawyer with no scientific or medical background, has profited from lawsuits against vaccine makers, as have many of his allies and advisors. “There is also a lot of plaintiffs’ playbook there,” Bourla said. “Everybody will start litigating.”

FDA deletes warning on bogus autism therapies touted by RFK Jr.‘s allies

anti-vaccine, autism, fda, fraud, health, Robert F Kenned Jr., Scams, treatment / 9u50fv / January 13, 2026

For years, the Food and Drug Administration provided an informational webpage for parents warning them of the dangers of bogus autism treatments, some promoted by anti-vaccine activists and “wellness” companies. The page cited specifics scams and the “significant health risks” they pose.

But, under anti-vaccine Health Secretary Robert F. Kennedy Jr.—who has numerous ties to the wellness industry—that FDA information webpage is now gone. It was quietly deleted at the end of last year, the Department of Health and Human Services confirmed to Ars Technica.

The defunct webpage, titled “Be Aware of Potentially Dangerous Products and Therapies that Claim to Treat Autism,” provided parents and other consumers with an overview of the problem. It began with a short description of autism and some evidence-based, FDA-approved medications that can help manage autism symptoms. Then, the regulatory agency provided a list of some false claims and unproven, potentially dangerous treatments it had been working to combat. “Some of these so-called therapies carry significant health risks,” the FDA wrote.

The list included chelation and hyperbaric oxygen therapy, treatments that those in the anti-vaccine and wellness spheres have championed.

Dangerous detoxes

Chelation is a real treatment for heavy metal poisoning, such as lead poisoning. But it has been co-opted by anti-vaccine activists and wellness gurus, who falsely claim it can treat autism, among other things. These sham treatments can come in a variety of forms, including sprays, suppositories, capsules, and liquid drops. Actual FDA-approved chelation therapy products are prescription only, the agency noted, and chelating certain minerals from the body “can lead to serious and life-threatening outcomes.”

Many anti-vaccine activists promote the false and thoroughly debunked claim that vaccines cause autism, and more specifically, that trace metal components in some vaccines cause the neurological disorder. For years, anti-vaccine activists like Kennedy focused on thimerosal, a vaccine preservative that contains ethylmercury. Thimerosal was largely removed from childhood vaccines by 2001 amid unfounded concerns. The removal made no impact on autism rates, and many studies have continued to show that it is safe and not a cause of autism. Anti-vaccine activists moved on to blame other vaccine components for autism, including aluminum, which is used in some vaccines to help spur protective immune responses. It too has been found to be safe and not linked to autism.

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

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.

Meet CDC’s new lead vaccine advisor who thinks shots cause heart disease

When the federal vaccine committee hand-picked by anti-vaccine Health Secretary Robert F. Kennedy Jr. meets again this week, it will have yet another new chairperson to lead its ongoing work of dismantling the evidence-based vaccine recommendations set by the Centers for Disease Control and Prevention.

On Monday, the Department of Health and Human Services announced that the chairperson who has been in place since June—when Kennedy fired all 17 expert advisors on the committee and replaced them with questionably qualified allies—is moving to a senior role in the department. Biostatistician Martin Kulldorff will now be the chief science officer for the Office of the Assistant Secretary for Planning and Evaluation (ASPE), HHS said. As such, he’s stepping down from the vaccine committee, the Advisory Committee on Immunization Practices (ACIP).

Kulldorff gained prominence amid the COVID-19 pandemic, criticizing public health responses to the crisis, particularly lockdowns and COVID-19 vaccines. He was a co-author of the Great Barrington Declaration that advocated for letting the deadly virus spread unchecked through the population, which was called unethical by health experts.

As ACIP chair, Kulldorff frequently made false and misleading statements about vaccine safety and efficacy that were in line with Kennedy’s views and statements. While Kulldorff presided over the committee, it made a series of decisions that were sharply denounced by scientific and medical groups as being based on ideology rather than evidence. Those include voting for the removal of the vaccine preservative thimerosal from some flu vaccines, despite well-established data indicating it is safe, with no evidence of harms. The committee also added restrictions to a combination measles, mumps, rubella, and varicella (chickenpox) MMRV vaccine and made an unprecedented effort to prevent Americans from getting COVID-19 vaccines, though the moves were largely ineffective.

In his new role, Kulldorff will be working with ASPE to provide analyses on health policy options, coordinate research efforts, and provide policy advice.

“It’s an honor to join the team of distinguished scientists that Secretary Kennedy has assembled,” Kulldorff said in a press release announcing his new role. “I look forward to contributing to the science-based public health policies that will Make America Healthy Again.”

The new chair, Kirk Milhoan

With Kulldorff moving on, ACIP will now be chaired by Kirk Milhoan, a pediatric oncologist with a track record for spreading COVID-19 misinformation and anti-vaccine views. In August 2021, the Hawaii Medical Board filed a complaint against Milhoan after he appeared on a panel promoting ineffective COVID-19 treatments, downplaying the severity of the disease, and spreading misinformation about COVID-19 vaccines, according to the Maui News. The complaint was dropped in April 2022 after state regulators said they had insufficient evidence to prove a violation of statutes regarding the practice of medicine.

While Milhoan claimed at the time that he is “pro-vaccine,” his statement, affiliations, and prescribing practices suggest otherwise. Milhoan is a member of the Independent Medical Alliance (formerly the Front Line COVID-19 Critical Care Alliance), a group of dubious health care providers set up amid the pandemic to promote the use of the anti-malaria drug hydroxychloroquine and the de-worming drug ivermectin to treat COVID-19. Both drugs have shown to be ineffective and potentially harmful when used to treat or prevent COVID-19. The IMA also emphasizes vaccine injuries while pushing vitamins and other unproven treatments.

In 2024, Milhoan appeared on a panel set up by Rep. Marjorie Taylor Greene (R-Ga.) to discuss alleged injuries from COVID-19 vaccines alongside other prominent anti-vaccine and COVID-19 misinformation voices. In his opening statement, Milhoan suggested that COVID-19 vaccines were causing severe cardiovascular disease and death in people aged 15 to 44—an unsubstantiated claim he frequently echoes. In his bio for the IMA, he touts that he offers treatment for “vaccine-related cardiovascular toxicity due to the spike protein.”

CDC data has found that boys and young men, aged 12 to 24, have a heightened risk of myocarditis (inflammation of the heart) after COVID-19 vaccination. However, the cases are rare, relatively mild, and almost always resolve, according to CDC data. In a COVID-19 safety data presentation in June, CDC staff scientists reported that its vast vaccine safety monitoring systems indicated that in males 12–24, there are 27 myocarditis cases per million doses of COVID-19 vaccine administered (roughly one case in 37,000 doses). In cases identified during 2021, 83 percent recovered within three months, with more than 90 percent recovering within the year. The monitoring data found no instances of cardiac transplant or death from COVID-19 vaccination.

While anti-vaccine activists have seized on this minor risk from vaccination, health experts note that the risk of myocarditis and other inflammatory conditions from a COVID-19 infection is significantly greater than the risk from vaccination. Exact estimates vary, but one CDC study in 2021 found that people with COVID-19 infections had a 16-fold higher risk of myocarditis than people without the infection. Specifically, the study estimated that there were 150 myocarditis cases among 100,000 COVID-19-infected patients versus just nine myocarditis cases among 100,000 people without COVID-19 infections and who were also unvaccinated. Similar to what’s seen with vaccination, the study found that young males were most at risk of myocarditis.

Kennedy’s allies attack on COVID-19 shots

Kennedy and his allies, like Milhoan, have consistently inflated the risk of myocarditis from COVID-19 vaccination, with some claiming without evidence that they have caused sudden cardiac arrest and deaths in young males, though studies have found no such link. In 2022, Milhoan and fellow ACIP member and conspiracy theorist Robert Malone were featured in a viral social media post suggesting that 50 percent of college athletes in the Big Ten athletic conference had myocarditis linked to COVID-19 vaccines, which could lead to deaths if they played. But the two were referencing a JAMA Cardiology study that examined subclinical myocarditis in Big Ten athletes after COVID-19 infection—not vaccination. In fact, researchers confirmed for an AFP fact check that none of the athletes in the study were vaccinated. And the rate of subclinical myocarditis in the group was 2.3 percent, not 50 percent.

Milhoan’s misinformation about the cardiovascular harms from COVID-19 vaccines seems particularly pertinent to the direction of Kennedy’s anti-vaccine allies. On Friday, Vinay Prasad, the Food and Drug Administration’s top vaccine regulator, sent a memo to staff claiming without evidence that COVID-19 vaccines have killed 10 children. The memo provides little information about the extraordinary claim, but it hints that the deaths were linked to myocarditis and found among reports submitted between 2021 and 2024 to the CDC’s Vaccine Adverse Event Reporting System (VAERS).

VAERS is a system by which anyone, including members of the public, can report anything they think could be linked to vaccines. The reports are considered a type of early warning system, but the vast majority of the reports submitted are not actually related to vaccines. Further, CDC scientists have thoroughly evaluated VAERS reports and ruled out deaths attributed to COVID-19 vaccines. Prasad’s memo—which experts have speculated was designed to be leaked to produce alarming headlines about child deaths—claimed that before Trump administration officials with anti-vaccine views began sifting through the data, these deaths were “ignored” by FDA and CDC scientists. Prasad also claimed that there could be many more deaths that have gone unreported, despite the fact that healthcare providers have been legally required to report any deaths that occurred after COVID-19 vaccination, regardless of cause.

This week’s ACIP meeting

In this week’s scheduled ACIP meeting on Thursday and Friday, COVID-19 vaccines don’t appear on the draft agenda. Instead, ACIP is expected to vote to remove a recommendation for a birth dose of the hepatitis B vaccine. That dose protects newborns from contracting the highly infectious virus from their mothers during birth or from other family or acquaintances shortly after birth. About half of the people infected with hepatitis B are not aware of their infections, and testing of mothers before birth is imperfect. That can leave newborns particularly vulnerable, as infections that start at or shortly after birth almost always develop into chronic infections that can lead to liver disease, liver transplant, and cancer. In a previous ACIP meeting, CDC staff scientists presented data showing that there are no significant harms of birth doses and there is no evidence that delaying the immunization offers any benefit.

The committee is also taking on the childhood vaccine schedule as a whole, though the agenda on this topic is not yet clear. In his memo, Prasad attacked the common practice of providing multiple vaccinations at once, hinting that it could be a way in which the committee will try to dismantle current childhood vaccination recommendations. On Tuesday, The Washington Post reported that the committee will examine whether the childhood vaccine schedule as a whole is causing allergies and autoimmune diseases, something Kennedy and his anti-vaccine organization have long floated despite evidence refuting a link.

Under clear attack are aluminum salt adjuvants, which are used in many vaccines to help spur protective immune responses. Aluminum salts have been used safely in vaccines for more than 70 years. The FDA notes that the most common source of aluminum exposure is from food and water, not vaccines.

RFK Jr.’s new CDC deputy director prefers “natural immunity” over vaccines

Under ardent anti-vaccine Health Secretary Robert F. Kennedy Jr., the Centers for Disease Control and Prevention has named Louisiana Surgeon General Ralph Abraham as its new principal deputy director—a choice that was immediately called “dangerous” and “irresponsible,” yet not as bad as it could have been, by experts.

Physician Jeremy Faust revealed the appointment in his newsletter Inside Medicine yesterday, which was subsequently confirmed by journalists. Faust noted that a CDC source told him, “I heard way worse names floated,” and although Abraham’s views are “probably pretty terrible,” he at least has had relevant experience running a public health system, unlike other current leaders of the agency.

But Abraham hasn’t exactly been running a health system the way most public health experts would recommend. Under Abraham’s leadership, the Louisiana health department waited months to inform residents about a deadly whooping cough (pertussis) outbreak. He also has a clear record of anti-vaccine views. Earlier this year, he told a Louisiana news outlet he doesn’t recommend COVID-19 vaccines because “I prefer natural immunity.” In February, he ordered the health department to stop promoting mass vaccinations, including flu shots, and barred staff from running seasonal vaccine campaigns.
