Kennedy's New Vaccine Panel Alarms Pediatricians with Inquiries into Long-Settled Questions
ATLANTA (AP) — U.S. Health Secretary Robert F. Kennedy Jr.'s new vaccine advisers alarmed pediatricians Wednesday by announcing inquiries into some long-settled questions about children's shots.
Opening the first meeting of Kennedy's handpicked seven-member panel, committee chairman Martin Kulldorff said he was appointing a work group to evaluate the 'cumulative effect' of the children's vaccine schedule — the list of immunizations given at different times throughout childhood.
Also to be evaluated, he said, is how two other shots are administered — one that guards against liver-destroying hepatitis B and another that combines chickenpox protection with MMR, the measles, mumps and rubella vaccine.
It was an early sign of how the Advisory Committee on Immunization Practices is being reshaped by Kennedy, a leading antivaccine activist before becoming the nation's top health official. He fired the entire 17-member panel this month and replaced it with a group that includes several anti-vaccine voices.
'Vaccines are not all good or bad,' Kulldorff said. 'We are learning more about vaccines over time' and must 'keep up to date.'
His announcement reflected a common message of vaccine skeptics: that too many shots may overwhelm kids' immune systems or that the ingredients may build up to cause harm. Scientists say those claims have been repeatedly investigated with no signs of concern.
Kids today are exposed to fewer antigens — immune-revving components — than their grandparents despite getting more doses, because of improved vaccine technology, said Dr. Paul Offit, a vaccine expert at Children's Hospital of Philadelphia.
The American Academy of Pediatrics announced Wednesday that it would continue publishing its own vaccine schedule for children but now will do so independently of the ACIP, calling it 'no longer a credible process.'
'The narrative that current vaccine policies are flawed and need 'fixing' is a distortion,' said the AAP's Dr. Sean O'Leary. 'These policies have saved trillions of dollars and millions of lives.'
The ACIP, created more than 60 years ago, helps the Centers for Disease Control and Prevention determine who should be vaccinated against a long list of diseases, and when. Those recommendations have a big impact on whether insurance covers vaccinations and where they're available, such as at pharmacies.
After Kennedy's abrupt dismissal of the existing expert panel, a number of the CDC's top vaccine scientists — including some who lead the reporting of data and the vetting of presentations at ACIP meetings — have resigned or been moved out of previous positions.
And shortly before Wednesday's meeting, a Virginia-based obstetrician and gynecologist appointed to the committee stepped down. According to the Trump administration, he withdrew during a customary review of members' financial holdings.
Scientists show data that COVID-19 vaccines protect pregnant women and kids
First on the committee's agenda Wednesday were COVID-19 vaccinations. Kennedy already sidestepped the panel and announced the vaccine will no longer be recommended for healthy children or pregnant women.
Yet CDC scientists told the panel that vaccination is 'the best protection' during pregnancy, and said most children hospitalized for COVID-19 over the past year were unvaccinated.
COVID-19 remains a public health threat, resulting in 32,000 to 51,000 U.S. deaths and more than 250,000 hospitalizations since last fall, according to the CDC. Most at risk for hospitalization are seniors and children under 2 — especially infants under 6 months who could have some protection if their mom got vaccinated during pregnancy, according to the CDC's presentation.
The new advisers weren't asked to vote on Kennedy's recommendations, which raise uncertainty about how easily people will be able to access COVID-19 vaccinations this fall.
After CDC staff outlined multiple overlapping systems that continue to track the vaccines' safety, several advisers questioned if the real-world data really is trustworthy.
Vote on RSV protections is postponed
Also Wednesday, the committee took up RSV, or respiratory syncytial virus, a common cause of cold-like symptoms that can be dangerous for infants.
In 2023, U.S. health officials began recommending two new measures to protect infants — a lab-made antibody for newborns and a vaccine for pregnant women — that experts say likely drove an improvement in infant mortality. The antibody proved to be 63% to 76% effective against emergency department visits for infants over the last year.
'People need to understand what a spectacular accomplishment these results are,' said ACIP member Dr. Cody Meissner, of Dartmouth.
The committee postponed until Thursday a vote on whether to recommend another company's newly approved antibody shot as well.
Flu shot recommendations to be debated
At its June meetings, the committee usually refreshes guidance for Americans 6 months and older to get a flu shot, and helps green light the annual fall vaccination campaign.
But a vote set for Thursday also promises controversy.
The panel is set to consider a preservative in a subset of flu shots that Kennedy and some antivaccine groups have falsely contended is tied to autism.
In preparation, the CDC posted a new report confirming that research shows no link between the preservative, thimerosal, and autism or any other neurodevelopmental disorders. By Wednesday afternoon, the analysis had been removed from the committee's website.

Rural schools feel the pinch from Trump administration's cuts to mental health grants
WASHINGTON (AP) -- In parts of rural upstate New York, schools have more than 1,100 students for every mental health provider. In a far-flung region with little public transportation, those few school counselors often are the only mental health professionals available to students. Hennessey Lustica has been overseeing grant-funded efforts to train and hire more school psychologists, counselors and social workers in the Finger Lakes region, but those efforts may soon come to end -- a casualty of the Trump administration's decision to cancel school mental health grants around the country. "Cutting this funding is just going to devastate kids," said Lustica, project director of the Wellness Workforce Collaborative in the Seneca Falls Central School District. "The workforce that we're developing, just in my 21 school districts it's over 20,000 kids that are going to be impacted by this and not have the mental health support that they need." The $1 billion in grants for school-based mental health programs were part of a sweeping gun violence bill signed by President Joe Biden in 2022 in response to the school shooting in Uvalde, Texas. The grants were meant to help schools hire more psychologists, counselors and other mental health workers, especially in rural areas. Under the Biden administration, the department prioritized applicants who showed how they would increase the number of providers from diverse backgrounds, or from communities directly served by the school district. But President Donald Trump's administration took issue with aspects of the grant programs that touched on race, saying they were harmful to students. "We owe it to American families to ensure that taxpayer dollars are supporting evidence-based practices that are truly focused on improving students' mental health," Education Department spokesperson Madi Biedermann said. School districts around the US cut off training and retention programs Lustica learned of her grant's cancellation in April in a two-page letter from the Education Department, which said the government found that her work violated civil rights law. It did not specify how. Lustica is planning to appeal the decision. She rejected the letter's characterization of her work, saying she and her colleagues abide by a code of ethics that honors each person's individuality, regardless of race, gender or identity. "The rhetoric is just false," Lustica said. "I don't know how else to say it. I think if you looked at these programs and looked at the impact that these programs have in our rural school districts, and the stories that kids will tell you about the mental health professionals that are in their schools, it has helped them because of this program." The grants supported programs in districts across the country. In California, West Contra Costa Unified School District will lose nearly $4 million in funding. In Alabama, Birmingham City Schools was notified it would not receive the rest of a $15 million grant it was using to train, hire and retain mental health staff. In Wisconsin, the state's Department of Public Instruction will lose $8 million allocated for the next four years. The state had used the money to boost retention and expand programs to encourage high schoolers to pursue careers in school-based mental health. "At a time when communities are urgently asking for help serving mental health needs, this decision is indefensible," state superintendent Jill Underly said in a statement. In recent House and Senate hearings, Democrats pressed Education Secretary Linda McMahon on the end of the grants and the impact on students. McMahon told them mental health is a priority and the grants would be rebid and reissued. "Anyone who works or spends time with kids knows these grants were funding desperately needed access to mental health care services," American Federation of Teachers president Randi Weingarten said in a statement. "Canceling the funding now is a cruel, reckless act that puts millions of children at risk." Grant programs put more mental health specialists in schools The strains on youth mental health are acute in many rural school districts. In one upstate New York district, half the students have had to move due to economic hardship in the last five years, creating instability that can affect their mental health, Lustica said. In a survey of students from sixth through 12th grade in one county, nearly half reported feeling sad or depressed most of the time; one in three said their lives lacked clear purpose or meaning. "We've got huge amounts of depression, huge amounts of anxiety, lots of trauma and not enough providers," Lustica said. "School is the place where kids are getting a lot of the services they need." Some families in the region are unable to afford private counseling or are unable to get their children to appointments given transportation challenges, said Danielle Legg, a graduate student who did an internship as a school social worker with funding from the grant program. "Their access to mental health care truly is limited to when they're in school and there's a provider there that can see them, and it's vital," Legg said. In the past three years, 176 students completed their mental health training through the program Lustica oversees, and 85% of them were hired into shortage areas, she said. The program that offered training to graduate students at schools helped address staffing needs and inspired many to pursue careers in educational settings, said Susan McGowan, a school social worker who supervised graduate students in Geneva City School District. "It just feels, to me, really catastrophic," McGowan said of the grant cancellation. "These positions are difficult to fill, so when you get grad students who are willing to work hand in hand with other professionals in their building, you're actually building your capacity as far as staffing goes and you're supporting teachers."

Startup Sells Plastic-eating Fungi Diapers to Tackle Landfill Waste
AUSTIN, Texas (Reuters) — Could baby poop and fungi work together to tackle landfill waste? That's the idea behind a new product launched by an Austin, Texas-based startup that sells disposable diapers paired with fungi intended to break down the plastic. Each of Hiro Technologies' MycoDigestible Diapers comes with a packet of fungi to be added to the dirty diaper before it is thrown in the trash. After a week or two, the fungi are activated by moisture from feces, urine and the environment to begin the process of biodegradation. Disposable diapers contribute significantly to landfill waste. An estimated 4 million tons of diapers were disposed of in the United States in 2018, with no significant recycling or composting, according to the Environmental Protection Agency. Diapers take hundreds of years to naturally break down. That means the very first disposable diaper ever used is still in a landfill somewhere. To tackle this, Hiro Technologies turned to fungi. These organisms — which include mushrooms, molds, yeasts and mildew — derive nutrients from decomposing organic matter. In 2011, Yale University researchers discovered a type of fungus in Ecuador that can feed on polyurethane, a common polymer in plastic products. They figured the fungus, Pestalotiopsis microspora, would be capable of surviving on plastic in environments lacking oxygen, like landfills. Hiro Technologies cofounder Tero Isokauppila, a Finnish entrepreneur who also founded medicinal mushroom company Four Sigmatic, said there are more than 100 species of fungi now known to break down plastics. 'Many, many moons ago, fungi evolved to break down trees, especially this hard-to-break-down compound in trees called lignin … Its carbon backbone is very similar to the carbon backbone of plastics because essentially they're made out of the same thing,' Isokauppila said. Three sealed jars at Hiro Technologies' lab show the stages of decomposition of a treated diaper over time. By nine months, the product appears as black soil — 'just digested plastic and essentially earth,' Isokauppila said. The company says it needs to do more research to find out how the product will decompose in real-world conditions in different climates and hopes to have the data to make a 'consumer-facing claim' by next year. It also plans to experiment with plastic-eating fungi on adult diapers, feminine care products and other now, it is selling 'diaper bundles' for $35 a week online. Cofounder Miki Agrawal, who was also behind period underwear company Thinx, said the MycoDigestible Diapers had been generating excitement from consumers and investors since launching about a month ago, declining to give details. Agrawal said the company had chosen to focus on diapers as the top household plastic waste item. 'There is a deleterious lasting effect that we haven't really thought about and considered,' Agrawal said. 'Because when you throw something away, no one's asking themselves, 'Where's away?''

Kennedy Says US Is Pulling Funding from Global Vaccine Group Gavi
LONDON (AP) — U.S. Health Secretary Robert F. Kennedy Jr. says the country is pulling its support from the vaccines alliance Gavi, saying the organization has 'ignored the science' and 'lost the public trust.' A video of Kennedy's short speech was shown to a Gavi meeting in Brussels on Wednesday, where the organization that has paid for more than 1 billion children to be vaccinated through routine immunization programs was hoping to raise at least $9 billion for the next five years. Kennedy, a longtime vaccine skeptic, mentioned Gavi's partnership with the World Health Organization during COVID-19, accusing them of silencing 'dissenting views' and 'legitimate questions' about vaccine safety. His speech also cast doubt on the diphtheria, tetanus and pertussis vaccine — which WHO and other health agencies have long deemed to be safe and effective. Gavi said in a statement Thursday that its 'utmost concern is the health and safety of children,' adding that any decision it makes on vaccines to buy is done in accordance with recommendations issued by WHO's expert vaccine group. Some doctors in the United States criticized the decision. Dr. Paul Offit, director of the Vaccine Center at the Children's Hospital of Philadelphia, said it was 'incredibly dangerous' and warned that defunding immunization would put millions of children at risk. Gavi is a public-private partnership including WHO, UNICEF, the Gates Foundation and the World Bank, and it is estimated that the vaccination programs have saved 18 million lives. The United States has long been one of its biggest supporters; before President Donald Trump's re-election, the country had pledged $1 billion through 2030. In just under four minutes, Kennedy called on Gavi 'to justify the $8 billion America has provided in funding since 2001,' saying officials must 'consider the best science available, even when that science contradicts established paradigms.' Kennedy said until that happens, the U.S. won't contribute further to Gavi. The health secretary zeroed in on the COVID-19 vaccine, which WHO, Gavi and other health authorities have recommended for pregnant women, saying they are at higher risk of severe disease. Kennedy called that a 'questionable' recommendation; his U.S. Centers for Disease Control and Prevention recently stopped recommending it. He also criticized Gavi for funding of a rollout a vaccine to prevent diphtheria, tetanus and pertussis in poorer countries, saying he'd seen research that concluded that young girls who got the vaccine were more likely to die from all other causes than children who weren't immunized. Gavi said scientists had reviewed all available data, including any studies that raised concerns, and that the diphtheria, tetanus and pertussis vaccine has 'played a key role in helping halve childhood mortality.' Some observational studies have shown that vaccinated girls do have a higher death rate compared to unvaccinated children, but there is no evidence the deaths are caused by the vaccine. But Offit said the studies cited by Kennedy were not convincing and that research examining links between vaccinations and deaths did not prove a causal connection. 'There's no mechanism here which makes biological sense for why the (diphtheria, tetanus and pertussis vaccine) might result in more children dying,' Offit said. Doctors Without Borders on Thursday predicted 'countless children will die from vaccine-preventable diseases' as a result of the U.S. withdrawing support for Gavi. 'To invoke misleading and inaccurate claims about vaccine safety as the pretext for cutting all global vaccine funding is cruel and reckless,' said Mihir Mankad, the charity's global health advocacy and policy director in the U.S. 'When we vaccinate in the community, parents line up for hours to give their children a chance to be protected from these deadly diseases. 'For these children, vaccination programs … are a matter of life and death.' Kennedy's recorded speech to Gavi came on the same day that his reconstituted U.S. vaccine advisory panel met for the first fired the previous 17-member panel this month and replaced it with a seven-member group that includes several vaccine skeptics.
