A U.S. well being secretary ready to spend billions to search a hyperlink between vaccines and autism. Vaccine skeptics shaping policy. A proposal to remove your entire federal immunization schedule for American youngsters.
Robert F. Kennedy Jr. has introduced a collection of once-unthinkable public-health proposals to the very best ranges of the Trump administration since turning into well being secretary early final 12 months, in accordance to Reuters interviews with 16 present and former officers with direct information of the discussions.
The officers, from the U.S. well being division and White House, shared particulars of inner discussions on situation of anonymity. Their first-hand accounts of Kennedy’s beforehand unreported efforts reveal a tenacious activist who has pushed via some of the largest adjustments to U.S. vaccine policy in decades – and who sought to go a lot additional than beforehand recognized to dismantle the established order.
“He’s an anti-vaccine activist. That’s who he is. That’s who he’s been for 20 years. To expect that as secretary of Health and Human Services he’d be anything other than that is wishful thinking,” mentioned Dr. Paul Offit, director of the Vaccine Education Center on the Children’s Hospital of Philadelphia and a long-time immunization adviser to the CDC.
Kennedy’s efforts to solid doubt on the security of photographs for frequent ailments are making it more durable to curb outbreaks, together with the largest U.S. resurgence of measles in additional than three decades, Offit mentioned.
“He scares people about vaccines, which only causes them not to get them,” Offit mentioned. “We’re screwed.”
The Department of Health and Human Services didn’t make Kennedy obtainable for an interview. Provided with particulars of Reuters’ reporting, spokeswoman Courtney Spencer disputed key particulars as unfaithful or inaccurate, together with the plan to remove your entire childhood immunization schedule. Spencer didn’t reply to a request for clarification about what was incorrect.
Kennedy has been unable to implement a number of parts of his vaccine agenda within the face of resistance from totally different corners of the federal government, together with inside the well being division and the White House, the Reuters reporting discovered. Furthermore, one of his most bold adjustments to public well being – eradicating vaccines for six out of 17 ailments from the really helpful childhood vaccination schedule – has been placed on maintain by a federal decide in response to a lawsuit from the American Academy of Pediatrics and different medical teams.
Despite the setbacks, Kennedy has pushed via main adjustments in his time on the well being division, which oversees nationwide well being businesses together with the Food and Drug Administration, National Institutes of Health and Centers for Disease Control and Prevention. The reforms embody winding down mRNA vaccine growth, withdrawing funding for a global vaccine alliance and tightening access to COVID photographs. Many well being consultants have mentioned his use of his place to elevate issues about vaccine security has sown confusion about which immunizations, if any, mother and father ought to give their youngsters.

Early this 12 months, Kennedy went to his director of the NIH, Jay Bhattacharya, with a expensive proposal, in accordance to two officers conversant in the request: The analysis company ought to spend $5 billion finding out the hyperlink between vaccines and autism. That would have devoted greater than a tenth of the NIH’s annual finances to investigating a speculation already refuted by scientists worldwide.
Kennedy in the end dropped the plan, which seemingly would have required congressional approval, after Bhattacharya satisfied him the company had devoted sufficient sources to researching autism’s causes, together with a $50 million effort launched in September, the officers mentioned.
Kennedy’s proposal got here shortly after he agreed to avoid talking publicly about vaccines, bowing to the request of a number of senior White House aides who feared his medical theories would harm Republicans politically.
But behind the scenes, the well being secretary has continued to search proof for his concept that many vaccines haven’t been correctly examined and may trigger a spread of harmful unwanted side effects, in accordance to eight of the present and former officers.
The NIH and Bhattacharya didn’t reply to requests for remark. HHS didn’t touch upon the $5 billion funding thought.
The NIH analysis request is one of a number of episodes recounted by present and former officers within the well being division and White House that solid gentle on Kennedy’s mission as well being secretary. It’s the most recent chapter for the scion of one of America’s political dynasties, whose life has veered from the trauma of the assassinations of his uncle and father and a years-long heroin habit to turning into a robust anti-vaxxer and flag-bearer of the Make America Healthy Again (MAHA) motion.
Kennedy received renown as an environmental lawyer who spent years preventing companies over air pollution and poisonous chemical substances. That contributed to his broad affect selling anti-vaccine theories for 2 decades, together with that many vaccines are extra harmful than the ailments they forestall, that they trigger autism and autoimmune problems in youngsters and include particles from aborted fetuses. His views are contradicted by scores of research exhibiting vaccines have saved hundreds of thousands of lives and prevented long-term well being issues from frequent ailments, whereas side-effects stay comparatively uncommon.
The 72-year-old’s reputation boomed in the course of the pandemic, when his insistence that COVID vaccines have been harmful and his opposition to lockdown restrictions attracted many Americans distrustful of authorities policy. He amplified conspiracy theories that accused U.S. authorities scientists of intentionally cashing in on the pandemic.
He has additionally spoken about startling incidents from his personal life, together with discovering a worm had lodged in his brain, inflicting reminiscence points, and dumping the carcass of a bear cub in New York City’s Central Park. He mentioned it was roadkill he had meant to take residence to pores and skin and retailer the meat, earlier than deciding to go away it in a park bike lane as a prank.
Kennedy was named well being secretary after he lower brief his personal run for president in 2024 and as an alternative endorsed Trump. He promised not to take vaccines away from Americans, each throughout his curtailed presidential marketing campaign in addition to his affirmation hearings in Congress wanted to approve his nomination to Trump’s cupboard.
He and Trump meet within the Oval Office each few months, most just lately in June, in accordance to 4 individuals briefed on the conversations. The president will typically ask what new efforts are underway on vaccines broadly and whether or not the well being secretary believes he’ll in the end show a hyperlink with autism, the individuals mentioned. Kennedy interprets the questions as a directive to forge forward with analysis on vaccine security, they added.
The White House didn’t dispute particulars about its relationship with Kennedy or conversations between the well being secretary, Trump and the president’s high aides. Spokesman Kush Desai mentioned the president helps Kennedy’s efforts to scale back the U.S. childhood immunization schedule consistent with different peer nations, which he didn’t specify. The Trump administration “continues to seek out answers for countless parents whose questions and concerns have long been ignored,” he added.

One of Kennedy’s earliest strikes in workplace was to elevate the query of whether or not childhood inoculations may cause autism.
The well being secretary has rejected research involving hundreds of thousands of individuals over the previous two decades which have concluded there is no such thing as a credible hyperlink. Leading medical organizations together with the American Academy of Pediatrics and American Medical Association say Kennedy’s refusal to settle for such findings each will increase vaccine hesitancy and devalues extra evidence-based efforts to assist households combating autism.
In November, Kennedy ordered the web site of the Centers for Disease Control and Prevention to be up to date to say the declare that vaccines don’t trigger autism is “not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism.” For years beforehand, it had mentioned that “studies have shown there is no link between receiving vaccines and developing autism,” citing a 2012 National Academy of Medicine overview of scientific papers and a 2013 CDC research.
The CDC didn’t reply to a request for remark for this text.
The well being secretary has tasked Stefanie Spear, his closest adviser, with main his division’s efforts to unearth any proof of a hyperlink, together with launching a collection of research into vaccine-related accidents. The pair return a few years, having partnered collectively on an environmental web site known as EcoWatch in 2011. Spear then joined Kennedy at Children’s Health Defense, the anti-vaccine group he based, in 2020, and served as press secretary throughout his 2024 presidential marketing campaign. Kennedy, Children’s Health Defense, and others have sued a number of information retailers, together with Reuters, alleging the media organizations colluded to exclude and censor them as a result of of their posts on COVID- and vaccine-related subjects. A movement to dismiss the lawsuit is pending in D.C. federal courtroom.
Spear has no scientific or public well being background, in accordance to her bio. Before becoming a member of Kennedy at Children’s Health Defense, she was a longtime environmental activist and communications skilled.

In HHS management conferences, Spear typically speaks for Kennedy even when he’s current, three individuals conversant in the matter mentioned. Kennedy has informed his high officers to search Spear’s approval for his or her new initiatives, three individuals mentioned. In workers conferences, Kennedy has directed officers to “run everything” via Spear, in accordance to two individuals who have heard the directive.
Spear, via HHS, declined an interview request and didn’t reply to questions on her function on the company.
Beginning this 12 months, Spear and different Kennedy aides requested officers on the U.S. Food and Drug Administration quite a few instances for entry to the FDA’s Sentinel BEST security system to assist HHS workers conduct research, together with into charges of autism and different circumstances amongst vaccinated versus unvaccinated youngsters, in accordance to 4 individuals conversant in the request.
The database is designed to monitor the security of FDA-approved merchandise together with vaccines after they hit the market by monitoring the medical health insurance claims and medical data of greater than 100 million Americans. Access to such programs, which include delicate info, is very restricted even inside HHS, sometimes restricted to a small quantity of profession officers and consultants.
The FDA initially refused Spear and different aides’ requests for entry out of concern that Kennedy and Spear have been on a “fishing expedition” for info to again up their autism argument, in accordance to two individuals conversant in the matter.
Shortly after taking workplace, Kennedy started expressing curiosity in charges of autism and different circumstances amongst vaccinated versus unvaccinated youngsters, and has raised the thought a number of instances, in accordance to 5 present and former officers. Leading well being consultants have mentioned such a comparability could be invalid as a result of vaccinated youngsters sometimes go to medical doctors extra typically than unvaccinated children do, so they have an inclination to obtain extra diagnoses for varied circumstances.
“With scientists at NIH, FDA, CDC, and universities, we are continuing to conduct studies to better understand vaccine safety and efficacy and to assess how vaccine exposure, timing, and patterns affect health across the lifespan,” Spencer mentioned in response to detailed questions on HHS’s vaccine efforts. “This work will generate evidence to inform vaccine recommendations.”
The FDA didn’t reply to a request for remark. Reuters couldn’t decide whether or not Spear finally bought entry to the info system.

Kennedy and Spear have labored to rewrite decades’ price of U.S. vaccine policy inside months, sidelining a big community of consultants at federal businesses and their collaborators within the medical and scientific communities, a dozen present and former officers mentioned. They have as an alternative labored with a good circle of longtime allies largely outdoors the federal government.
Chief amongst these adjustments was a choice to shrink the CDC’s childhood immunization schedule, which guides state vaccination necessities and medical health insurance protection. By January, that they had eliminated vaccines for six ailments out of a listing of 17 routinely given to youngsters, which have all been proven to forestall sickness and demise from frequent ailments.
Last summer season, although, Kennedy and Spear had larger ambitions, in accordance to three individuals with direct information of their plans: to remove your entire childhood schedule.
They wished to inform households that the use of the vaccines for all 17 ailments may very well be left to “shared clinical decision-making,” which means mother and father would resolve with their healthcare suppliers which photographs, if any, to give their youngsters. They anticipated that state well being officers and medical teams just like the American Academy of Pediatrics would offer their very own pointers to fill the hole, the three individuals mentioned.
The thought of abandoning the entire schedule alarmed a number of well being officers, together with then-FDA commissioner Marty Makary and Tracy Beth Høeg, one of his high deputies, 4 sources mentioned. Makary and Høeg created a listing of “core essential vaccines” in an effort to steer the well being secretary away from the intense path. They ranked the really helpful immunizations so as of significance and confirmed which of them have been additionally thought of essential by peer nations.
Public well being consultants have broadly mentioned that the U.S. schedule was broader than another developed nations together with Denmark, Norway and Sweden however not an outlier, and met the precise well being wants of Americans. They argued that dropping vaccines with out proof would needlessly expose many extra youngsters to issues and even demise from preventable ailments. The likes of Germany, Britain, France, Canada and Australia additionally advocate vaccinating youngsters towards roughly 15 to 17 ailments.

By the autumn, below the pushback from well being division officers on the FDA and elsewhere, together with White House aides, Kennedy agreed to solely scale back the childhood schedule, in accordance to three individuals conversant in the discussions. He and his advisers focused a slimmer program consistent with the size of the schedule in Denmark, which solely has 6 million residents, gives common well being care and immunizes its youngsters towards far fewer ailments than most developed international locations. Medical consultants broadly mentioned that schedule doesn’t translate to a rustic just like the United States, with greater than 300 million residents and enormous gaps in entry to medical care and medical health insurance.
Still, the well being secretary stored altering his thoughts on what to take away.
Kennedy and his advisers debated eliminating the measles, mumps and rubella (MMR) shot within the fall, in accordance to the three individuals. He didn’t transfer ahead as a result of of attainable political blowback, with a measles outbreak raging in South Carolina on the time, they mentioned.
Some of his different solutions – together with eradicating the polio vaccine from the schedule – have been discarded after pushback from White House officers, the three individuals mentioned. HHS spokeswoman Spencer mentioned that eradicating MMR and polio photographs “had never been considered.”
A advice for COVID photographs for kids had already been dropped in May, when it was introduced in a social media publish that includes Kennedy and Makary. Spear personally intervened to assist draft the U.S. vaccine protocol for hepatitis B photographs in December, three sources mentioned. She offered language endorsed by Kennedy’s hand-picked board of immunization advisers, many of whom share his skepticism of vaccines, to take away a common advice for hepatitis B photographs beginning at beginning.
In the tip, the shorter childhood schedule was largely equivalent to Denmark’s when vaccines for 4 extra ailments have been eliminated in January. Kennedy made the adjustments unilaterally somewhat than going via a panel of consultants, as has lengthy been customary, and Spear wrote the accompanying report justifying the adjustments, in accordance to three individuals conversant in the method. Trump hailed the brand new schedule as “rooted in the Gold Standard of Science”. “Many Americans, especially the ‘MAHA Moms’, have been praying for these COMMON SENSE reforms for many years,” he wrote on social media, referring to mother and father who again Kennedy’s insurance policies.
However, in March a federal decide blocked Kennedy’s decreased childhood schedule, additionally ruling the well being secretary’s vaccine advisory board was not lawfully constituted after he fired all its members and changed them. HHS has appealed the ruling.

In his mission to rewrite U.S. immunization practices, Kennedy has additionally relied on Aaron Siri, a long-time ally and litigator. Siri is one of probably the most distinguished advocates difficult American well being businesses and vaccine makers over alleged accidents.
Siri has repeatedly argued that many childhood vaccines have been really helpful by the CDC with out ample security knowledge. In 2019, he filed a lawsuit towards the CDC demanding it produce research demonstrating that vaccines routinely given to infants don’t trigger autism, or admit it didn’t have such research. Both sides agreed to dismiss the lawsuit after the CDC produced a listing of research. Siri says that the analysis the company offered didn’t disprove a hyperlink to autism for these photographs.
In 2022, he petitioned the FDA to revoke approval for 2 COVID vaccines and one polio shot, alleging their security testing in scientific trials was insufficient. The FDA denied the previous petition, and hasn’t but dominated on the latter.
Siri isn’t a authorities official. But he helped Kennedy and Spear vet potential appointees throughout the HHS, FDA and CDC in the course of the presidential transition in early 2025, three individuals conversant in the method mentioned.
Kennedy on a number of events informed aides final 12 months that any vaccine-related policy or change ought to obtain enter from Siri earlier than it went out, in accordance to two individuals instantly conversant in the remarks. The well being secretary regularly conferenced Siri into inner well being division policy conferences by way of speaker, in accordance to the 2 individuals. Siri participated within the discussions about whether or not to take away the MMR and polio photographs from the childhood schedule, the administration officers mentioned.
Siri mentioned in response to Reuters’ questions that he was not conscious of a plan to take away these vaccines, or of a Kennedy requirement to run policy adjustments by him.
“I sure wish they would have followed that purported directive,” Siri mentioned. “I would not need to continue to send them demands, keep following up when they get ignored, and continue to fight HHS and its agencies in dozens of lawsuits related to vaccine policy.”
HHS policy motion may have an effect on Siri’s personal legislation enterprise, in accordance to 4 authorized consultants interviewed.
Siri and Kennedy have for years known as for a reexamination of the method for looking for compensation for vaccine accidents. Patients who have been harmed by photographs on the U.S. immunization schedule can solely search a restricted quantity of damages from a fund run by HHS, referred to as the Vaccine Injury Compensation Program (VICP).
Congress created this system within the Nineteen Eighties to guarantee an ample provide of vaccines. Vaccine makers typically function on skinny revenue margins for photographs utilized by hundreds of thousands of individuals and argue they’d be compelled out of enterprise if sufferers may file lawsuits with out restraint.

Yet Siri has argued that Americans harmed by vaccines ought to give you the option to sue drugmakers instantly, as an alternative of going via a authorities program. Suing a drug producer in civil courtroom permits plaintiffs to search greater damages and demand that the businesses disclose inner knowledge on product security and decision-making. Pharmaceutical corporations don’t have this safety for different medicines.
Siri mentioned just lately that eradicating routine suggestions for photographs on the CDC schedule, as Kennedy has tried to do, would permit such lawsuits to proceed. He has additionally publicly known as for extra unwanted side effects to be included on the checklist of well being issues acknowledged by VICP. That would permit extra individuals to file claims for compensation.
Kennedy has mentioned he’s working to change VICP from inside the authorities, although has not specified what reforms he’s looking for. As well being secretary, he has authority to set many guidelines governing the scheme, together with which vaccine-related medical circumstances are compensated rapidly and that are topic to in depth litigation by plaintiffs.
HHS spokesperson Spencer mentioned Siri is “one of many people who have made recommendations about how to improve the VICP.”
Siri’s agency represents individuals who say they’ve been harmed by vaccines and is presently litigating over 400 pending VICP claims, in accordance to Westlaw knowledge. In March, Siri filed a petition on behalf of the Informed Consent Action Network — a gaggle that has regularly attacked vaccine security — asking Kennedy to add over 300 varieties of accidents to VICP, together with a number of circumstances associated to autism.
Richard Hughes IV, the lead lawyer suing HHS on behalf of the American Academy of Pediatrics over the childhood vaccine schedule adjustments, mentioned he disagrees with Siri’s petition, believing it could bloat VICP with inappropriate accidents. But he acknowledges this system wants reform. Claimants face lengthy delays in getting paid, whereas damages quantities want to be raised, he mentioned. “We want the program to work,” he added.
Dorit Reiss, a professor at UC Law San Francisco, mentioned that if the well being division added the accidents Siri known as for in his petition to this system, his agency and others like them could be able to file hundreds extra vaccine harm claims and earn mandated attorneys charges paid from the VICP fund.
Siri informed Reuters that his agency works on behalf of Americans injured by vaccines to convey the reduction they’re entitled to below VICP. If the compensation system have been to be reformed to permit extra claimants to sue drugmakers instantly, he mentioned, there must be “very few, if any” main awards of damages if vaccines are as protected as marketed.
