RFK Jr.'s vaccine advisory panel to review shots for children
Health and Human Services (HHS) Secretary Robert F. Kennedy Jr.'s newly remade federal vaccine advisory panel will examine the cumulative effect of the childhood and adolescent vaccine schedule, the panel's chairman said Wednesday.
The Advisory Committee on Immunization Practices (ACIP) will also weigh recommendations for vaccines that have long been on the market, including measles and hepatitis B.
Martin Kulldorf made the announcement at the start of the first meeting of the ACIP since Kennedy dismissed all 17 previous members less than two weeks ago, accusing them of conflicts of interest.
Kennedy appointed a new group of eight members two days later. One withdrew just before Wednesday's meeting during a review of his financial holdings, leaving seven members to vote on vaccine recommendations during the meeting.
'Secretary Kennedy has given this committee a clear mandate to use evidence based medicine. We're making vaccine recommendations and that is what we will do. Vaccines are not all good or bad,' Kulldorf said Wednesday.
The health chief, who co-founded the anti-vaccine group Children's Health Defense and served as its chairman before being confirmed to lead HHS, has long called for an investigation into the number of childhood shots, saying they have been inadequately studied.
The review will be undertaken by two new ACIP work groups, Kulldorff said, though it's not clear if they have been staffed yet. One group will be focused on the childhood and adolescent vaccine schedules and the other will focus on shots that have been approved for seven or more years.
He specifically mentioned the recommendation for giving newborns the hepatitis B vaccine as well as the combination measles, mumps, rubella (MMR) and chickenpox shots.
The panel chair added that the group will also consider religious objections to MMR vaccines derived from fetal cell lines and may look at an MMR vaccine approved in Japan.
'The number of vaccines that our children and adolescents receive today exceed what children in most other developed nations receive, and what most of us in this room received when we were children,' Kulldorf said.
He added that it is also important 'to evaluate the cumulative effect of the recommended vaccine schedule. This includes interaction effects between different vaccines, the total number of vaccines, cumulative amounts of vaccine ingredients and the relative timing of different vaccines.'
For decades, the Centers for Disease Control and Prevention's (CDC) independent advisory panel recommended which shots Americans should get and when.
The Affordable Care Act requires all insurance companies to cover, for free, the vaccines recommended by the panel. Those recommendations also help states decide which shots should be mandated for schoolchildren.
Kennedy's shakeup is throwing that system into chaos. Outside physician and public health groups have been pressuring insurance companies to continue covering vaccines, no matter what ACIP does.
'Part of the role of ACIP is to look at vaccines across the lifespan,' said Chrissie Juliano, executive director of the Big Cities Health Coalition. 'I think the important thing to note is we need to reevaluate vaccine recommendations based on whether science has changed, not based on whether the people who sit on a committee change, or in administration changes. And I think that's where we start to lose the public's trust.'
The American Academy of Pediatrics (AAP) announced Wednesday that it would no longer take part in ACIP hearings.
'We won't lend our name or our expertise to a system that is being politicized at the expense of children's health,' AAP President Susan Kressly said in a video posted on social platform X.
Ahead of the meeting, the insurance industry trade group America's Health Insurance Plans (AHIP) issued a statement that its plans are 'committed to ongoing coverage of vaccines to ensure access and affordability for this respiratory virus season.'
'We encourage all Americans to talk to their health care provider about vaccines,' the group wrote.
As the meeting kicked off, President Trump's nominee to lead the CDC, Susan Monarez, was on Capitol Hill testifying in front of the Senate Health, Education Labor and Pensions (HELP) Committee during a confirmation hearing.
Monarez said she does not see a causal link between vaccines and autism, and told Sen. Lisa Murkowski (R-Alaska) she hopes experts will step up and volunteer to fill the panel's remaining slots.
'These are not easy positions to fill. It takes a lot of time and commitment from some of these highly trained technical experts to want to participate,' Monarez said. 'They need to have a depth and a breadth of technical experience to be able to understand immunological processes, to understand statistical analysis.'
Sen. Bill Cassidy (R-La.), HELP Committee, lamented the 'rushed' meeting with a diminished panel.
'Given that there is no confirmed CDC director, along with an ACIP panel which has very few members, many of whom lack broad vaccine and immunology immunological expertise, there are concerns about the rushed nature of this process,' Cassidy said.
The Louisiana Republican also expressed concern that Thursday's ACIP schedule will feature a presentation on thimerosal given by Lyn Redwood, a longtime anti-vaccine activist. Redwood is president emerita of Children's Health Defense.
Thimerosal is a preservative used in some influenza vaccines, and anti-vaccine leaders have long linked it to autism in children, a claim that's been debunked.
'I will note that there are people who are critics of thimerosal who've been asked to testify, but no one speaking of the substantial evidence that in the amounts used in vaccines, thimerosal is safe,' the senator said.
Prior to the meeting, a document was posted to ACIP's website summarizing that all available evidence shows thimerosal is safe and is not linked to autism or other neurological issues. That document was no longer available on Wednesday.
'I will say going forward, if the ACIP hearing today is being used to sow distrust, I would ask as you go forward that you would make sure that there really was a balanced perspective,' Cassidy said.

RFK Jr. appoints longtime anti-vaccine ally Lyn Redwood to HHS position
Health Secretary Robert F. Kennedy Jr. has hired an anti-vaccine advocate and longtime ally to a position at the Health and Human Services Department, a person familiar with the matter confirmed to ABC News. Lyn Redwood served for years as president of Children's Health Defense, the anti-vaccine organization founded by Kennedy. Her exact role at HHS is unclear. Andrew Nixon, a department spokesman, told ABC News he had no comment. Meanwhile, Redwood is expected to deliver a presentation at the Advisory Committee on Immunization Practices (ACIP) meeting on Thursday using a report on thimerosal that is currently available online, which contains misleading information and cites a source that apparently does not exist, according to one author, who told ABC News he is falsely cited in the report. MORE: Why is thimerosal back on the CDC's agenda when it's barely in flu shots anymore? Thimerosal is a preservative in vaccines meant to prevent contamination. It's currently used in about 4% of flu shots but was removed from routine childhood vaccines in 2001. "To the best of my knowledge, the study in rats referred to in the planned CDC presentation by Lyn Redwood listing Berman RF as first author does not exist," Robert F Berman, Ph.D., professor emeritus at the University of California Davis, said. "I have not published a paper with that title or with that set of co-authors in the journal Neurotoxicology in 2008. Also, none of my research has made any statements about possible thimerosal effects on microglia in the brain or resulting in neuroimmune effects," Berman said. That citation has since been removed from the revised presentation online. The Washington Post was first to report Redwood's appointment to HHS. Redwood has held a longstanding belief that mercury exposure through thimerosal-containing vaccines causes autism. Specifically, she has directly attributed her son's autism to mercury exposure from childhood vaccines as recently as October 2024 in a podcast with RFK Jr. Decades of research has found no link between autism and vaccines or any vaccine preservative, including thimerosal. MORE: What to expect from the upcoming CDC vaccine advisory committee meeting with RFK Jr.'s new members "Thimerosal was removed from all routine childhood vaccines in the US out of an abundance of caution - it is still used as a preservative in much of the world. Many studies have demonstrated that it is safe and has no association with neurodevelopmental disorders," Dr. Sean O'Leary, chair of the American Academy of Pediatrics' Committee on Infectious Diseases and AAP's liaison to ACIP, told ABC News. A thorough report of existing evidence by the Institute of Medicine in 2004 concluded, "the body of epidemiological evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism." The Centers for Disease Control and Prevention also says, "research does not show any link between thimerosal and autism." While this preservative is not used frequently in the U.S., if it is removed or no longer recommended in those remaining flu shots, doctors worry it could lead to unnecessary gaps in vaccine access and the potential for harm by not protecting these people. "Any decrease in the number of flu vaccines available will likely result in fewer people being vaccinated and subsequently, more hospitalizations and deaths. Its removal could also signal to the general public unwarranted safety concerns," O'Leary said. MORE: CDC vaccine advisory panel to study child immunization schedule, delays RSV shot vote At least one vaccine expert said she shuddered Wednesday at the idea of Redwood joining HHS. Fiona Havers, a 13-year CDC veteran who worked on vaccine policy, told ABC News in a statement, 'Lyn Redwood is well-known for spreading vaccine misinformation. It is troubling that Redwood may now have an official role within HHS and will potentially be in a position to interfere with official messaging about vaccine safety.' ABC News has reached out to Redwood for a comment. Redwood and Kennedy have long been close. In a conversation between the two of them on Kennedy's podcast last year, Kennedy credited Redwood with being the figure who 'coordinated' the 'stalking crusade' by mothers who convinced Kennedy to begin looking into the potential harms of vaccines in the early 2000s. Redwood was also involved in Kennedy's recent presidential campaign, coordinating volunteer and petition-gathering trainings in Georgia, her home state, according to sign-up pages on the campaign's website.

What to know about thimerosal, a target of RFK Jr.'s new CDC vaccine advisers
Vaccines Disability issues Federal agencies Children's healthFacebookTweetLink Follow In the 1930s, vaccine makers began using a preservative called thimerosal to stave off microbial growth in their products. For the next six decades, it didn't receive much notice; ill effects appeared limited to minor local injection-site reactions, according to the US Food and Drug Administration. That changed in 1999, when US health officials asked pharmaceutical companies to remove thimerosal from vaccines. There was no evidence that it caused harm in the quantities used, but thimerosal contains a form of mercury, and questions had emerged about whether it could cause neurotoxicity when given in childhood vaccinations. Vaccine makers have removed it from all but a few shots, such as multidose vials of flu vaccine. In the meantime, subsequent studies have confirmed no link between thimerosal in vaccines and neurodevelopmental issues, including autism, and autism rates have continued to rise. So public health experts were puzzled when the preservative appeared on the agenda for this week's meeting of outside vaccine advisers to the US Centers for Disease Control and Prevention. 'I actually don't know any pediatric practices that even use that multidose influenza vaccine,' said Dr. Sean O'Leary, a pediatrician at Children's Hospital Colorado and former liaison to the CDC's Advisory Committee on Immunization Practices, or ACIP, for the American Academy of Pediatrics. The group is meeting on Wednesday and Thursday for the first time since US Health and Human Services Secretary Robert F. Kennedy Jr. dismissed the committee's previous 17 members, claiming they had conflicts of interest, and days later installed eight new advisers. Public health experts and lawmakers have called into question the credentials and backgrounds of some of the new panelists, and just before the meeting began, one member withdrew during the financial holdings review, an HHS spokesman said, bringing the panel down to seven. A presentation 'regarding thimerosal in vaccines' is scheduled for Thursday morning, followed by 'proposed recommendations' specifically about thimerosal in flu vaccines, according to an agenda posted Monday. The meeting is scheduled to conclude with a vote on the latter, a move that could lead to official CDC policy if adopted by agency leadership – or, without a confirmed director in place, by Kennedy. The last-minute addition of thimerosal to the agenda was a red flag for vaccine experts, who consider the science settled and fear that Kennedy – who led an anti-vaccine group called Children's Health Defense – is seeking to sow doubt about vaccine safety. Another former Children's Health Defense leader, Lyn Redwood, is slated to make a presentation on the topic at the meeting. Here's how thimerosal became such a hot-button issue. In 1997, Rep. Frank Pallone, a New Jersey Democrat concerned about mercury pollution in his community's lakes and rivers, attached an amendment to a US Food and Drug Administration reauthorization bill that would require the agency to catalogue intentionally introduced mercury compounds in drugs and food. That led to a possibly startling discovery: 'As people looked in vaccines, there was the potential that, by six months of age, infants could have received more thimerosal than was listed in several sources of what was considered safe levels of mercury,' said Dr. Walter Orenstein, who was director of the National Immunization Program at the CDC at the time. But those limits were set for methylmercury, the kind found in some fish, which is known to be toxic. Thimerosal contains ethylmercury, a different compound that's 'intrinsically less stable, and more readily metabolized, than methylmercury,' said Dr. Matthew Rand, an associate professor in the Department of Environmental Medicine at the University of Rochester who studies mercury toxicity. That means it's cleared from the body more quickly than methylmercury, according to the CDC, 'and is therefore less likely to cause any harm.' The FDA notes that there were no existing guidelines for ethylmercury. Still, the finding led to a number of emergency meetings among federal health officials and outside groups to determine what should be done, Orenstein recalled. 'While there was no evidence of harm from thimerosal, the general feeling was, 'let's get rid of it, because we don't need it,' ' he said. Moving to single-dose containers alleviated the need for a preservative, although it came at a higher expense for manufacturers. In 1999, the FDA sent a letter to manufacturers of US vaccines requesting their plans to remove thimerosal, and by 2001, the compound had been removed from or reduced in all vaccines routinely recommended for children under 6 in the US, according to the CDC. The message from public health agencies, Orenstein said, was 'we're going to make safe vaccines even safer.' But the die was cast. Vaccines had already been tied to autism in 1998 by British doctor Andrew Wakefield, who published a since-retracted paper that claimed the measles-mumps-rubella vaccine was linked to autism, although not because of thimerosal – the MMR vaccine never contained the preservative. Still, parents of children with autism were seeking answers. One of those parents was Redwood, who said that in 1999, she tallied up her son's mercury exposure and found 'at two months of age, he had received 125 times his allowable exposure to mercury based on EPA's guidelines in his weight.' 'That was a real answer for me,' Redwood said in a video posted by Children's Health Defense this month, 'because my son at this time was almost 5 years old, and he had regressed developmentally after his first year of life and was diagnosed with autism.' Redwood, a nurse practioner, decided to become an advocate, speaking at events and publishing papers about thimerosal and autism. The uproar over a potential link between thimerosal and autism came as a surprise to Orenstein and colleagues. 'Mercury itself had never been implicated as a major cause of autism,' Orenstein said. 'But this was a major, major concern.' It led to a number of studies of the issue, including a 2004 assessment by the Institute of Medicine (now known as the National Academy of Medicine) that concluded 'the body of epidemiological evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism.' It made the same conclusion for MMR vaccines and autism. A 2010 study by the CDC also found no link. And 'even after thimerosal was removed from almost all childhood vaccines, autism rates continued to increase,' the agency noted, 'which is the opposite of what would be expected if thimerosal caused autism.' Still, those who continued to push the disproven autism connection included Kennedy, who published a book in 2014 called 'Thimerosal: Let the Science Speak.' Its subtitle calls for the 'immediate removal of mercury – a known neurotoxin – from vaccines.' It rejects the findings of the 2004 Institute of Medicine report and warns that millions of children in the US and around the world 'appear to be at risk of injury from the thimerosal in vaccines.' Thimerosal is still present in 'a small percentage of flu vaccines, confined to multidose vials,' according to a post from the Vaccine Integrity Project, a group focused on countering vaccine misinformation that was started at the University of Minnesota's Center for Infectious Disease Research and Policy, or CIDRAP. The group suspects that thimerosal is included on ACIP's agenda this week – with a presentation by Redwood and a vote by the committee – 'to put greater focus on and generate more public discussion about vaccine risk.' HHS didn't return a request for comment about Redwood's involvement in this week's meeting, and Redwood declined to comment. Her presentation slides, however, were posted ahead of the meeting and continued to claim thimerosal presents safety risks. One slide initially included in the presentation cited a study in animals that appeared not to exist; its apparent lead author told CNN he'd published a study with a similar title, but in a different journal, in different animals, and with dramatically different findings — ones that didn't appear to show a link between autism and thimerosal. The slide presentation was subsequently updated to remove that slide. CDC staff also posted its own review of the data, citing nearly two dozen studies showing 'the evidence does not support an association between thimerosal-containing vaccines and autism spectrum disorder or other neurodevelopmental disorders.' During her Senate Health, Education, Labor and Pensions committee confirmation hearing on Wednesday, Dr. Susan Monarez, President Donald Trump's pick to lead the CDC, said, 'I have not seen a causal link between vaccines and autism.' The decision to remove thimerosal from most vaccines, despite no evidence of harm, had other consequences. At the same time the FDA made its request to vaccine makers, US health authorities advised that babies born to mothers known to be negative for hepatitis B not receive a shot for that virus at birth, but at two months to 6 months of age, as thimerosal was phased out. But about 10% of hospitals 'suspended use of the hepatitis B vaccine for all newborns, regardless of their level of risk,' wrote Dr. Paul Offit, a vaccine scientist at the Children's Hospital of Philadelphia and a member of the FDA's outside advisory committee on vaccines, in a 2007 perspective piece in the New England Journal of Medicine. 'One three-month-old child born to a Michigan mother infected with hepatitis B virus died of overwhelming infection.' Orenstein looks back on the decision to remove thimerosal as a hard one. 'The fear would be keeping it in there, doing a study over two or three years and then it showed harm, and lo and behold, for three years, we used this vaccine and this component was harmful,' he said. 'Since we didn't know what the results would be of any of the studies at the time, we thought it better to just get it out of there. 'The autism issue,' he added, 'didn't play any role in the initial decision.' CNN's Brenda Goodman contributed to this report.

Inside the unusual, RFK-appointed panel that's deciding on childhood vaccines
The world just got its first look at the inner workings of the new vaccine panel appointed by Health and Human Services Secretary Robert F. Kennedy and their immediate focus: childhood vaccines. The eight new members of the Advisory Committee on Immunization Practices met for the first time on June 25, where ACIP Chair Martin Kulldorf announced at the top of the meeting how the panel plans to reexamine the childhood immunization schedule. "The number of vaccines that our children and adolescents receive today exceeds what children in most other developed nations receive and what most of us in this room received when we were children," he said. "In addition to studying and evaluating individual vaccines, it's important to evaluate the cumulative effect of the recommended vaccine schedule." Kulldorff added the committee will also establish workgroups to investigate vaccines that protect against measles, mumps and rubella and hepatitis B. Kennedy fired all 17 original members of the committee on June 9 and appointed its new members, which included some vaccine skeptics, a few days later. Their recommendations will have wide-ranging implications, guiding vaccine requirements for schools and impacting a government program offering free vaccinations for about half of America's kids. Many experts are concerned the panel's actions will sow doubt in vaccines that have been deemed safe and effective. More: Trump US CDC nominee backs vaccines as life-saving 'To raise doubt about our traditional pediatric vaccines that have saved millions of lives, particularly during one of the worst measles outbreaks we have had in years, is irresponsible and will cost lives,' said Dr. Gretchen LaSalle, a family physician in Spokane, Washington, who represents the American Academy of Family Physicians for an ACIP workgroup. The Centers for Disease Control and Prevention panel also reviewed data about COVID-19 vaccines, immediately questioning their safety and effectiveness. They also raised questions about the study design, methodologies and surveillance monitoring systems behind the data, which Dr. Pamela Rockwell, clinical professor of family medicine at the University of Michigan Medical School, addressed as standard of medical research. "Our efforts, through a very robust system of checks and balances, are to create vaccines and vaccination programs that result in the most benefit with the least harm," said LaSalle, from AAFP. The committee didn't vote on COVID-19 vaccine recommendations for the fall and isn't expected to reconvene until 'September/October,' according to the CDC website. 'Stakes are simply too high': Criticisms and controversies Public comment during the meeting was a mix of voices raising criticisms and concerns about potential harm, from different perspectives. Nurses, pediatricians, public health experts and mothers flooded the public comment portion of the meeting to criticize Kennedy's decision to fire the 17 original ACIP members and advocate the protective benefits of vaccines. 'The Big Cities Health Coalition is deeply concerned that many routine vaccines may soon become inaccessible or unaffordable for millions of Americans if ACIP makes changes based on ideology rather than science,' Chrissie Juliano, executive director of the Big Cities Health Coalition, said during the public comment section. 'The stakes are simply too high to let that happen.' Others criticized vaccine mandates and medical exemption restrictions. 'With many new members in place, the ACIP must now act to prevent continued harm,' said Kim Mack Rosenberg, general counsel for Children's Health Defense, the anti-vaccine group founded by Kennedy. The planned vote on a new shot for respiratory syncytial virus, or RSV, was postponed due to time constraints. The ACIP meeting was held despite a national outcry from health experts, officials and organizations calling for a delay. Sen. Bill Cassidy, a Louisiana Republican and physician, urged officials to wait until the panel is 'fully staffed with more robust and balanced representation – as required by law – including those with more direct relevant experience.' 'Although the appointees to ACIP have scientific credentials, many do not have significant experience studying microbiology, epidemiology or immunology,' Cassidy, the chairman of the Senate Committee on Health, Education, Labor, and Pensions, said in a social media post. 'In particular, some lack experience studying new technologies such as mRNA vaccines, and may even have a preconceived bias against them.' Contributing: Ken Alltucker, USA TODAY.
