​In 1996, Guinea-Bissau seemed like an ideal research post for budding pediatrician Lone Graff Stensballe. Her supervisor, a fellow Dane named Peter Aaby, had spent nearly two decades collecting data on 100,000 people living in the mud brick homes of the West African country’s capital.

Aaby and his partner, Christine Stabell Benn, believed that the years of research in the impoverished country had yielded a major discovery about vaccines — and what they described as “non-specific effects”: The measles and tuberculosis vaccines, which were derived from live, weakened viruses and bacteria, they said, boosted child survival beyond protecting against those particular pathogens.

But, the scientists said, shots made from deactivated whole germs, or pieces of them, such as the diphtheria-tetanus-pertussis shot, caused more deaths — especially in little girls — than getting no vaccine at all.

The World Health Organization repeatedly and inconclusively examined these astonishing findings, which tended to elicit shrugs from the researchers’ colleagues in global health.

Then came Donald Trump, covid, and the administrative reign of anti-vaccine advocate Robert F. Kennedy Jr.

Suddenly, Aaby and Benn weren’t just sending up distant smoke signals from a far corner of the planet. They were confidently voicing their views and policy prescriptions online and in medical journals. The “framework” for “testing, approving, and regulating vaccines needs to be updated to accommodate non-specific effects,” their team wrote in a 2023 review.

And the Trump administration has taken notice.

“They became more strident in saying that their findings were real and that the world needed to do something about it,” said Kathryn Edwards, a Vanderbilt University vaccinologist who has been aware of Aaby’s work since the 1990s. “And they became more aligned with RFK.”

Kennedy, as secretary of the Department of Health and Human Services, cited one of Aaby’s papers to justify slashing $2.6 billion in U.S. support for Gavi, a global alliance of vaccination initiatives. The cut could result in 1.2 million preventable deaths over five years in the world’s poorest countries, the nonprofit agency has estimated. Kennedy has frozen $600 million in current Gavi funding over largely debunked vaccine safety claims.

Kennedy described the 2017 paper as a “landmark study” by “five highly regarded mainstream vaccine experts” that found that girls who received a diphtheria-tetanus-pertussis, or DTP, shot were 10 times more likely to die from all causes than unvaccinated children.

In fact, the study was far too small to confidently make such assertions, as Benn later acknowledged. In a study of historical data that included about 500 girls, four of those vaccinated against DTP in a three-month period of infancy died of unrelated causes, while one unvaccinated girl died during that period. A follow-up published by the same group   

​Here in Washington, we’ve been hearing about tensions between the White House and one of its most controversial — but, at least in some circles, most popular — figures: Robert F. Kennedy Jr.

Polling of likely voters indicates that the Health and Human Services secretary can be an asset to Republicans when he’s talking about improving the nation’s food supply or labeling ultraprocessed foods. But when he’s talking about removing recommendations for routine childhood vaccinations, he can be a detriment.

So, when I learned Kennedy would be taking his show on the road to my home state of Ohio, where populist figures tend to perform well, I knew I had to be there.

How would a politician who built his reputation seeding widespread doubts about routine childhood immunizations stay away from one of the core messages he’s preached for years?

Well, it turns out, he starts by reading a book about a trash truck to preschoolers.

The trip took us across northern Ohio, from a regenerative farm in Huron owned by two brothers who grow colorful vegetables to the Cleveland Clinic, where Kennedy masked up entering an operating room of a heart surgery patient.

In the end, though, Kennedy couldn’t escape the vaccine talk.

Speaking at the City Club of Cleveland, Kennedy raised doubts about the safety of vaccines that had been — up until last year — universally recommended to prevent hepatitis B, an incurable disease.

He called for parents to “be given that choice” on administering the vaccine to newborns, a remark that gave way to cheers and applause from half the room.

The other half groaned and booed.

When I sat down with the health secretary for a few minutes in an Ohio farmhouse, Kennedy ticked off his accomplishments during his first year in office; redesigning federal nutrition guidelines and defining ultraprocessed foods for the American public were among them.

As his list grew longer, I thought about the mothers I’d talked to over the last year who had become increasingly nervous about taking their infants out in crowded places amid a raging measles outbreak and the growing threat from other infectious diseases.

What was his message for those parents, I asked?

“I would say everybody should be vaccinated — against measles,” Kennedy told me. “But we need to pay more and more attention to chronic disease. All of the vaccine-preventable, infectious diseases put together kill probably 10,000 Americans a year.” 

The number of deaths is closer to 50,000, according to scientific researchers.

As had been rumored for weeks, Marty Makary is out as commissioner of the FDA after a chaotic 13 months presiding over drama in every corner of the agency. That leaves Robert F. Kennedy Jr.’s Department of Health and Human Services with three senior vacancies: FDA commissioner, surgeon general, and director of the Centers for Disease Control and Prevention. All must pass through the Senate committee chaired by Sen. Bill Cassidy (R-La.), who has had a troubled relationship with Kennedy and President Donald Trump.

Meanwhile, opponents of abortion remain unhappy with the Trump administration, demanding a more robust federal crackdown on abortion in general and the abortion pill in particular. The administration, meanwhile, has been pushing policies to encourage families to have more children.

This week’s panelists are Julie Rovner of KFF Health News, Rachel Cohrs Zhang of Bloomberg News, Alice Miranda Ollstein of Politico, and Lauren Weber of The Washington Post.

Among the takeaways from this week’s episode:

Makary is leaving his role as FDA commissioner after a troubled tenure. While tensions over granting approval for fruit-flavored vapes appear to have been the last straw, Makary led an agency in near-constant turmoil that cast a shadow over its employees and the industries it oversees. Kyle Diamantas, who will serve as acting director, is not a doctor but rather a lawyer with ties to the Trump family.

The fate of telehealth access to the abortion pill mifepristone hung in the balance this week after the Supreme Court extended its stay on a lower-court order halting that access. Should the court affirm that lower-court ruling, it would be the biggest change to abortion access nationwide since it overturned the constitutional right to an abortion in 2022.

And the hantavirus outbreak on a cruise ship continue  

​GWINNETT COUNTY, Ga. — In a midwife’s suburban Atlanta home with a playground and chicken coop outside, Madie Collins lay on an examination table while the midwife measured her pregnant belly. Unlike at many a doctor’s office, no crinkly paper sheet covered the table and no antiseptic chill lingered in the air. The room next door, where Collins’ appointment began, was filled with children’s toys and scented candles and warmed by a wood-burning stove.

The certified professional midwife pressed the button on a handheld Doppler ultrasound machine she placed on Collins’ belly. “That’s her heartbeat,” she said to Collins’ 3-year-old daughter, who sat beside her mom as a whooshing sound filled the room. “I think Mommy’s baby’s right here.”

The midwife is not licensed as a nurse. In Georgia, that makes what she’s doing illegal. KFF Health News agreed not to identify her by name.

Georgia is one of seven states where delivering babies can earn non-nurse midwives, at minimum, a cease-and-desist letter requiring them to end their careers. In North Carolina, it’s a misdemeanor. In New York, it’s a felony.

Meanwhile, demand for their services is increasing. Intended home births rose by 42% nationally from 2020 to 2024, according to the National Center for Health Statistics, and those births are often overseen by certified professional midwives. In Georgia, they rose by 72%. Midwives who assist with home births typically see clients from prenatal appointments through several visits after childbirth, providing more postpartum checkups than most new mothers receive.

Home births make up 1.5% of deliveries nationwide. In the eight states where they were most common in 2024 — Hawai‘i, Idaho, Montana, Pennsylvania, Utah, Vermont, Wisconsin, and Wyoming— they made up 3-5% of births.

As that number rises, midwifery advocates said, regulating the practice with licenses would allow home births to be safer. Free birth — without the help of a skilled professional before or after labor — can be dangerous for mothers and babies.

“People are going to keep having their babies at home, and they deserve a trained provider,” said Missi Burgess, president of the Georgia chapter of the National Association of Certified Professional Midwives.

For decades, professional midwives have been advocating for laws to legalize and regulate their profession. More lawmakers have supported those efforts in the past 15 years, with 36 states and Washington, D.C., allowing them to get licensed to deliver babies. Last year, a wave of state lawmakers — in Georgia, Mississippi, Nebraska, New York, North Carolina, Ohio, and West Virginia — tried to add their states to the list, although none of their bills has become law.

Certified professional midwives deliver babies in homes or birth centers. Rather than attend nursing school — which many can’t afford — they earn a nationally recognized certificate by attending at
