US Health and Human Services Secretary Robert F. Kennedy Jr.'s recent move to replace a federal panel of vaccine advisers should help restore Americans' trust in the US Centers for Disease Control and Prevention, the nominee to lead that agency told senators on Wednesday.
Dr. Susan Monarez, President Donald Trump's pick for CDC director, testified before the Senate Health, Education, Labor and Pensions Committee amid increasing alarm from lawmakers about Americans' eroding confidence in vaccine safety under Kennedy's leadership of HHS.
The Senate hearing happened the same morning that the CDC's newly appointed Advisory Committee on Immunization Practices convened its first meeting in Atlanta despite calls from lawmakers, including HELP Chairman Bill Cassidy, a Republican from Louisiana, to postpone the meeting.
'The secretary had to make a decision related to ensuring that the ACIP could be supportive of restoring public trust,' Monarez said when asked about the reassembled panel.
Kennedy dismissed all 17 ACIP members this month, citing conflicts of interest. Two days later, he named eight new members, several of whom had records of criticizing vaccine safety. As of Wednesday morning, one nominee, Dr. Michael Ross, had withdrawn during a federal review of members' financial holdings.
Monarez, a microbiologist and infectious disease expert who has served across several federal health agencies over the years, said she was not familiar with the details of the shakeup but would be open to placing more people on the committee. Although the CDC director can recommend experts to join ACIP, the HHS secretary ultimately signs off on appointments.
'These are not easy positions to fill,' Monarez said. 'It takes a lot of time commitment from some of these highly trained technical experts to want to participate.'
Cassidy and several Democratic senators sought reassurances from Monarez that she would protect ACIP's integrity as CDC director.
'Part of the concern is that the people on the panel, although scientifically credentialed, no one has the experience of [an] immunization [background] to say, 'Wait a second: The evidence that you're presenting, there's a lot more evidence to say it's not true.' That responsibility will fall on you,' Cassidy said, echoing concerns that he shared about the panel Monday and pointing to a specific presentation, slated for Thursday, on the preservative thimerosal in certain vaccines.
Cassidy also brought up mRNA, the technology in widely used Covid-19 vaccines that has early promise in other immunizations and potential therapies. Some vaccine critics, including new ACIP member Dr. Robert Malone, have touted unproven theories that mRNA vaccines can cause cancer and other serious side effects.
'If we turn our back on that platform, we're turning our back on solutions to Lyme disease, which is terribly debilitating, to HIV, which is a scourge,' Cassidy said. He pressed Monarez to include experts on the ACIP panel who have experience with mRNA and immunology.
She agreed.
'We absolutely need highly trained scientists and professionals to be able to participate,' Monarez said. ACIP 'is such a vital part of the CDC. It's such a vital, vital process.'
The nominee also said several times that 'vaccines save lives.'
At other points during the hearing, Monarez distanced herself from other Trump administration directives, including mass layoffs at the CDC and proposals to eliminate certain programs.
Monarez, who served as the CDC's deputy director from January to March and later as acting director, said repeatedly that she was not familiar with the details of layoffs that stalled lead poisoning prevention efforts or anti-tobacco education campaigns.
Monarez said she was not involved in personnel decisionmaking during those Department of Government Efficiency-led layoff, though she later said she worked with CDC staff to 'make sure we were reinforcing' the reduction in force plans.
Kennedy has been critical of the addition of fluoride to public water supplies, but Monarez was more noncommittal when questioned by Maryland Sen. Angela Alsobrooks, a Democrat, about the HHS secretary's plans to end CDC support of fluoridation in state and local drinking water.
'Fluoride is an important component to oral health,' Monarez said.
Alsobrooks noted that the public water supply in Potomac, Maryland, where Monarez lives, is fluoridated and asked Monarez whether it is safe.
'I believe the water in Potomac, Maryland, is safe,' Monarez replied.
Trump chose Monarez to lead the agency after withdrawing his first nominee, former Florida congressman Dr. Dave Weldon, from consideration. In a public letter after his withdrawal, Weldon accused Cassidy and Sen. Susan Collins of Maine of cratering his nomination amid concerns over his vaccine views.

With kids flocking to pools amid heat wave, this Pennsylvania swim club is offering free swim lessons
Kids are flocking to the pools as the Philadelphia area continues to experience a heat wave, making water safety even more important. At Nile Swim Club in Yeadon, a free swim program is underway to teach kids the skills to conquer their fears of water and stay safe in the pool. Haalah Cunningham, 11, was at the swim club, learning how to swim for the first time. "It's definitely important to me because most of my friends have pools and I love going over their houses like being in their pools and if I can't swim, I really can't do much," she said. Haalah joined several other kids taking lessons as part of the swim club's No Child Will Drown in Our Town swim program. It's a free 10-day class that teaches kids how to swim. Haalah's mom says making sure her daughter knew how to swim was a priority for her this summer. "Making sure [my kids] are safe and able to help themselves if they ever get in trouble in the water is very important to me," said Sanayy Miller, the mother of Haalah Cunningham. With more kids flocking to the pools during this heat wave, water safety is even more important. According to the CDC, drowning is the leading cause of death for children ages 1 through 4. It's also an issue that disproportionately affects kids of color "Everyone is drawn to the pool, everyone wants to swim but when you don't know how to swim it can become a very dangerous place," said Lisa Marie Ivory, president of Nile Swim Club. Ivory is fighting to change those numbers, and it's been a part of the club's mission for decades. The club opened in 1959 after its founders were denied access to a local pool during segregation. Ivory and the club's work continues to be focused on making sure all kids know how to swim. "We want our kids to have all the same opportunities that all the other children have had. And it's really important to us that kids in Pennsylvania, not just here in the area of the swim club, learn how to swim," she said. Nile Swim Club's No Child Will Drown in Our Town swim program continues into July. If you're interested and want to sign up, you can find more information on the club's website.

Intel leaders say new intelligence shows Iran's nuclear sites could take "years" to rebuild
The heads of two key American intelligence agencies issued statements Wednesday on what they said was "new" intelligence on the damage resulting from the recent U.S. strikes on Iran's nuclear facilities, each noting the Iranian program was likely to have been set back by "years." The statements were released after President Trump decried a leaked, preliminary assessment produced by the Defense Intelligence Agency that said Tehran's nuclear program had only been pushed back by a matter of months. Mr. Trump had ordered airstrikes on three Iranian nuclear facilities late Saturday, adding to a more than weeklong Israeli campaign against targets in Iran. CIA Director John Ratcliffe said in a statement Wednesday that "a body of credible intelligence indicates Iran's Nuclear Program has been severely damaged by the recent, targeted strikes." "This includes new intelligence from a historically reliable and accurate source/method that several key Iranian nuclear facilities were destroyed and would have to be rebuilt over the course of years," Ratcliffe's statement said. It added the agency would continue to collect "additional reliably sourced information" to share with policy makers, and, when possible, to provide updates to the public. A CIA spokesperson declined to elaborate on the intelligence referenced by Ratcliffe's statement, including the confidence level associated with it or whether it included Israeli or other foreign intelligence. Earlier on Wednesday, Director of National Intelligence Tulsi Gabbard also wrote on X that "new intelligence confirms what President Trump has stated numerous times: Iran's nuclear facilities have been destroyed." "If the Iranians chose to rebuild, they would have to rebuild all three facilities (Natanz, Fordow, Esfahan) entirely, which would likely take years to do," Gabbard's statement read. An intelligence official later confirmed to CBS News that the information shared by Gabbard was based on new American intelligence, but declined to specify its confidence level. Neither of the statements directly addressed some of the questions raised by lawmakers and nonproliferation experts in the aftermath of the strikes about what kinds of residual nuclear capabilities Iran may have retained. There are also conflicting views about whether Iranian officials had managed to transport enriched uranium away from the sites before they were bombed. The DIA assessment indicated at least some of the enriched uranium had been moved, according to one source familiar with it. But when asked whether enriched material was successfully moved during a press availability following the NATO summit in the Netherlands on Wednesday, President Trump said, "We think we hit them so hard and so fast, they didn't get to move." The president also said the U.S. and Iran were expected to hold talks "next week." The format remains unclear, for now, but special envoy to the Middle East Steve Witkoff is expected to lead the talks, if they happen, two U.S. officials told CBS News. Witkoff has spoken with the Iranian foreign minister, and recently, Secretary of State Marco Rubio and Vice President JD Vance have also become more involved in the diplomacy, a U.S. and regional diplomat told CBS News. Both Ratcliffe and Gabbard were slated to participate in a classified Senate briefing on Tuesday on the U.S. strikes in Iran, but the session was cancelled and rescheduled for Thursday. The House is expected to be briefed on Friday. It is unclear whether both leaders will still participate in both briefings. Ratcliffe and Gabbard's statements on Wednesday also included criticism of the leak to media outlets of the DIA assessment, which a spokesperson for that agency later said was issued with low confidence and would be refined as additional intelligence becomes available. The initial DIA report said the entrances to two Iranian nuclear sites — including the Fordo facility — were sealed off in the strikes, but that Iran could reconstitute elements of its program once it dug out and made repairs to water and electrical systems, according to sources familiar with it. The assessment also provided a range of possibilities for how long it could take for Iran to regain access to the underground facilities and resume some operations, ranging from a few months to less than a year, one source familiar with the assessment told CBS News. Administration officials have blasted those findings, which are at odds with Mr. Trump's repeated assertions that Saturday night's airstrikes "obliterated" Iran's nuclear facilities. Speaking from the NATO summit, Mr. Trump said the airstrikes set back Iran's program by "basically decades." "They said it could be limited or it could be very severe. They really didn't know," Mr. Trump said of the U.S. intelligence assessments. Appearing alongside the president, Secretary of Defense Pete Hegseth said Wednesday the damage to the sites was extensive. "If you want to make an assessment of what happened at Fordo, you'd better get a big shovel and go really deep, because Iran's nuclear program is obliterated," he told reporters. Chairman of the Joint Chiefs of Staff Gen. Dan Caine said in a press availability on Sunday following the strikes that a full battle damage assessment of the strikes "will take some time." He said at the time that the three targets "sustained extremely severe damage and destruction." Hegseth is set to lead a press briefing Thursday morning, which Mr. Trump said "will prove both interesting and irrefutable." , , and contributed to this report.

What to know about thimerosal, a target of RFK Jr.'s new CDC vaccine advisers
A century ago, one of the biggest safety concerns about vaccines involved bacterial contamination. In 1916, four young children died in South Carolina after receiving typhoid vaccine that had been contaminated with Staphylococcus aureus bacteria. Twelve years later, 12 children in Queensland, Australia, died from tainted immunizations against diphtheria. 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.
