The Make America Healthy Again movement has always had a split personality. Many of the movement’s leaders are fervent anti-vaccine activists whose views are at odds with scientific evidence and out of step with most Americans. At the same time, MAHA’s tenets include eating more vegetables and getting enough sleep, which is perfectly reasonable advice; it’s just hard to take seriously from people who, like Health Secretary Robert F. Kennedy Jr., wax nostalgic about catching measles.

Since becoming Health and Human Services secretary, Robert F. Kennedy Jr. has repeatedly denied that he opposes vaccines and has toned down some of his more extreme rhetoric on the subject. But in a keynote speech today at a conference for Children’s Health Defense, the anti-vaccine organization he founded, the old Kennedy was back. He complained about safety studies, floated disproven theories about a link between vaccines and autism, and all but declared himself an anti-vaxxer.

When the Amish man emerged from his barn to greet me, he had no idea that his newborn son’s death had become national news. The man wore a straw hat, black trousers, and suspenders over a long-sleeved blue shirt; one of his similarly dressed sons was guiding a horse-drawn plow in a nearby field.
The man told me that, like most Amish people, he and his family don’t watch TV or use the internet. They don’t read the newspaper either.

As of today, it seems likely that the nation’s next surgeon general will, at least, have an active medical license. President Trump announced that he was pulling his nomination for Casey Means, a wellness influencer who dropped out of her surgical residency in 2018, in a Truth Social post this afternoon. The move is the latest setback for Health and Human Services Secretary Robert F. Kennedy Jr.

The White House has reportedly urged Health and Human Services Secretary Robert F. Kennedy Jr. to avoid talking about vaccines, but this morning he had no choice. When he appeared before the House Ways and Means Committee—the first of seven congressional testimonies that he’s scheduled to give in the coming days as part of the 2027-budgeting process—members pressed him on the issue, which he has written and spoken about nearly nonstop for two decades.

Tony Lyons knows how Republicans can win the midterm elections later this year. All they need to do, as he explained in a memo to GOP leaders in February, is embrace the Make America Healthy Again movement, or at least the popular parts of it, like banning soda from SNAP benefits and ditching artificial food dyes. Divisive anti-vaccine issues, in contrast, must be “addressed carefully and with nuance.

When he was interviewed onstage at the Conservative Political Action Conference on Saturday, Health and Human Services Secretary Robert F. Kennedy Jr. was asked a question unlikely to be on anyone’s mind in the midst of upheaval in the department he oversees and a conflict in the Middle East: “Who’s stronger—you or Secretary of War Pete Hegseth?”
The exchange was emblematic of the role that Kennedy and other HHS officials played during the four-day conference.

Today, Acting CDC Director Jay Bhattacharya said something that no other prominent health leader in the Trump administration has. “I think it is vital that every kid in this country get the measles vaccine. Absolutely vital,” he told CDC staff at a meeting this morning.
That declaration went further than Health and Human Services Secretary Robert F. Kennedy Jr.

Casey Means has, to say the least, modified her tone. When she testified today in front of the Senate’s health committee, the nominee for surgeon general didn’t, as she is normally wont to do, delve into her experiences with psychedelics or endorse raw milk. She also did not rail at length against birth control.

In the United States, polio is a memory, and a fading one at that. The last major outbreak here happened in 1952; the virus was declared eliminated in 1979. With all of that behind us, you can see how someone—say, Kirk Milhoan, the chair of the CDC’s vaccine advisory committee—might wonder whether giving the polio vaccine to American kids still makes sense. “We need to not be afraid to consider that we are in a different time now,” Milhoan said on the podcast Why Should I Trust You? last week.

Nearly a year ago, Health Secretary Robert F. Kennedy Jr. pledged during his confirmation hearing to support the CDC’s childhood-vaccine schedule. Yesterday, he broke that promise. The Department of Health and Human Services has announced that the CDC will drop several vaccines from its recommendation list. With that move, Kennedy has shown that he can change the vaccine schedule by fiat.
Kennedy appears to have a clear road if he wants to do more.

If Robert F. Kennedy Jr., the secretary of Health and Human Services, did bother to ask CDC scientists about using their website to turn anti-vaccine talking points into agency guidance, it didn’t matter much. “My understanding is that none of the leadership were asked about it, or if they were asked about changing the website, they did not agree with the change,” Daniel Jernigan, the former director of the National Center for Emerging and Zoonotic Infectious Diseases, told me.

Russell Brand had found his people, that much was clear. Last Saturday, in front of 800 fans in a hotel ballroom in Austin, the comedian doled out praise for Robert F. Kennedy Jr. (whom he called “Great Brother Kennedy”), disdain for the medical establishment (“flat-out evil”), and gratitude for Jesus Christ (“Thank God we have a forgiving God that died for us”). He also told a bunch of dick jokes and, later, called me a Nazi.

It was a strange weekend for employees of the Centers for Disease Control and Prevention, to say the least. On Friday, hundreds of workers at the agency, many of whom have been furloughed since the federal government shut down on October 1, found out they were being fired as part of widespread layoffs across federal agencies. Less than a day later, a curt follow-up email landed in many of their inboxes informing them that they weren’t being let go after all. No explanation, no apology.

At a press conference today, President Donald Trump dispensed one clear piece of medical advice to American parents in a rambling, repetitive monologue: Don’t. Take. Tylenol. He told pregnant women that they could help keep their children safe from autism by not taking the drug whenever they could avoid it (“fight like hell,” he instructed). He advised parents not to give Tylenol to their young children.

Three months into its tenure, Robert F. Kennedy Jr.’s handpicked vaccine advisory committee has taken down one of its easiest targets.
Today, its members voted to limit the national guidance for a childhood vaccine that has helped protect infants against some of the most dangerous and fast-spreading viral diseases in the United States.

For nearly a decade, the immunologist and biochemist William Parker has tried, with little success, to persuade other scientists to take seriously his theory that acetaminophen—better known by the brand name Tylenol—is the primary cause of autism.

This spring, months before the recent dramatic departures from the CDC, Robert F. Kennedy Jr. battled with the agency’s scientists during the very first public-health crisis of his tenure as health secretary. As measles tore through a remote community in West Texas, Kennedy waffled on the vaccine and promoted alternative remedies, such as vitamin A. So the CDC pushed back.

In February 2010, Michelle Obama launched “Let’s Move!” with a wide-ranging plan to curb childhood obesity. The campaign took aim at processed foods, flagged concerns about sugary drinks, and called for children to spend more time playing outside and less time staring at screens. The campaign was roundly skewered by conservatives.

The Centers for Disease Control and Prevention is coming undone. The White House announced last night that it had ousted the agency’s newly sworn-in director, Susan Monarez, whose lawyers insist that she still has her job because only President Donald Trump himself can fire her. (Yes, it’s a mess.) Four top officials resigned yesterday.

Last month, a small company in San Francisco announced that it had a plan to manufacture gold—not merely a flake or a nugget, but tons of the stuff. According to a paper written by one of Marathon Fusion’s co-founders (and not yet peer reviewed), the alchemist’s dream could be achieved not by mixing powders in a crucible but by tweaking atoms that were superheated during the process of nuclear fusion. The gold wouldn’t be the end game, more like a side hustle.

When Reddit rebranded itself as “the heart of the internet” a couple of years ago, the slogan was meant to evoke the site’s organic character. In an age of social media dominated by algorithms, Reddit took pride in being curated by a community that expressed its feelings in the form of upvotes and downvotes—in other words, being shaped by actual people.

Robert Malone—a medical doctor and an infectious-disease researcher—recently suggested that the Pfizer and Moderna vaccines might actually make COVID-19 infections worse. He chuckled as he imagined Anthony Fauci announcing that the vaccination campaign was all a big mistake (“Oh darn, I was wrong!”) and would need to be abandoned.
