Who Makes Vaccine Policy Decisions in RFK Jr.’s Health Department?
For decades, as an activist, Robert F. Kennedy Jr. resisted the scientific consensus that vaccines are safe and necessary to prevent serious disease. Now at the helm of the nation’s health department, he has begun to put his extreme views into practice, ousting veteran scientists and installing allies across the nation’s health agencies to enact major shifts in vaccine policy.
Some of Mr. Kennedy’s hires are activists who have worked for years alongside him. Others are scientists who say they broadly support vaccines but publicly criticized Covid shots or mandates during the pandemic. Many of these scientists have begun to question the safety or value of other shots, reflecting the views of Mr. Kennedy. The following account is based on previous statements made by these officials and on interviews with current and former health agency leaders.
F.D.A. chief medical and scientific officer
Critical of Covid boosters and shots for healthy kids
F.D.A. commissioner
Skeptical of certain vaccines
Dr. Vinay Prasad
Dr. Marty Makary
The agency’s new vaccine lead and chief medical officer, Dr. Vinay Prasad, has called himself an “extreme pro-vaccine person,” and Dr. Marty Makary, the agency’s commissioner, said last week that “we believe in vaccines.”
But the two officials, who sharply criticized vaccine mandates as academic researchers during the pandemic, have expressed doubts about the safety and necessity of Covid boosters for healthy children and adults. This summer, Dr. Prasad overrode some agency scientists who favored widespread access to Covid shots, narrowing the vaccine’s eligibility to those 65 and older and to younger people with underlying medical conditions.
Last week, Dr. Makary echoed the views of Mr. Kennedy when he publicly questioned the longstanding recommendation to give the hepatitis B vaccine at birth. That shot is credited with nearly eliminating the transmission of the disease from mother to infant.
Dr. Prasad replaced a veteran at the agency, Dr. Peter Marks, who resigned in March and said that Mr. Kennedy’s aggressive stance on vaccines posed a danger to the public.
In June, Mr. Kennedy fired all 17 members of a powerful C.D.C. expert panel, the Advisory Committee on Immunization Practices. Insurance companies and government programs like Medicaid are required to cover the vaccinations that the panel recommends.
Mr. Kennedy handpicked eight new members that month, half of whom had expressed skepticism of vaccines at some point. (One has since stepped down.) Others have little expertise in immunology or vaccines.
On Monday, Mr. Kennedy appointed five more members, just days before the group meets to review recommendations for multiple vaccines. Some of the newly selected members have been critical of Covid vaccines or vaccine mandates.
Dr. Robert Malone is a controversial figure. He performed early experiments using mRNA in the 1980s but gained notoriety during the pandemic for claiming that Covid vaccines were unsafe, contradicting volumes of studies.
Martin Kulldorff, a biostatistician, has been generally supportive of vaccines but opposed Covid vaccination for children and vaccine mandates. Vicky Pebsworth, a nurse with a doctorate in public health, serves on the board of the National Vaccine Information Center, a nonprofit that disseminates misinformation about the risks of vaccination.
Dr. Malone and Dr. Kulldorff have served as paid expert witnesses in legal cases against vaccine makers. Dr. Pebsworth claimed in a lawsuit that a survey of families of unvaccinated children supported a hypothesis that a rise in the number of recommended childhood vaccines explained an epidemic of chronic disease.
Another panel member, Retsef Levi, is a management and health analytics expert at the Massachusetts Institute of Technology. He has been critical of a variety of vaccines and has called for Covid vaccines to be pulled from the market.
Dr. Evelyn Griffin, an obstetrician and gynecologist, questioned the safety and effectiveness of Covid vaccines in a hearing in the Louisiana House of Representatives in 2021. Dr. Kirk Milhoan, a pediatric cardiologist, questioned the safety and effectiveness of Covid vaccines at a 2024 event led by Representative Marjorie Taylor Greene, Republican of Georgia. Catherine M. Stein is an epidemiology professor who in 2022 called for an end to Covid vaccine mandates at universities.
Dr. Cody Meissner is a professor of pediatrics who opposed vaccine mandates and has questioned the ongoing need for Covid vaccines for children and pregnant women. He previously served on the advisory committee and is widely considered to be the most qualified member.
The others are not known to have spoken out against vaccines. They are Dr. Joseph R. Hibbeln, a nutritional neuroscientist; Dr. James Pagano, an emergency medicine physician; Hillary Blackburn, a pharmacist; and Dr. Raymond Pollak, a surgeon and transplant specialist.
The C.D.C. director has the power to accept or reject the immunization committee’s recommendations. The current acting director is Mr. Kennedy’s deputy at the Department of Health and Human Services, Jim O’Neill, a former biotechnology executive. The previous director, Susan Monarez, said she was forced out because she would not agree to accept the newly re-formed committee’s recommendations.
A special adviser to the C.D.C. director, Stuart Burns, is a critical player driving the health secretary’s agenda at the agency. Mr. Burns has been quietly working to remake the immunization committee and its agenda.
Mr. Burns is not a scientist but he worked for decades as a staff member for Republican congressmen known for their vaccine skepticism. One is Dr. Dave Weldon, a former representative from Florida who was also Mr. Kennedy’s original choice for C.D.C. director. The White House withdrew Dr. Weldon’s nomination just hours before his confirmation hearing because some Senate Republicans were concerned about his stance on vaccines.
Mr. Burns works closely with three other Kennedy hires who serve H.H.S. but also work closely with the C.D.C. Dr. Reyn Archer is a former Texas health commissioner who has questioned the safety and value of the Covid vaccine on social media. He serves as a liaison between the health secretary’s office and the C.D.C., and has been helping Mr. Burns to develop and guide the immunization committee.
David Geier is a steadfast figure in the anti-vaccine movement who has spent more than 20 years trying to establish a link between vaccines and autism, despite scientific consensus that there is none. Mr. Geier, who is listed as a senior data analyst in the H.H.S. directory, was given access to federal data on post-vaccination side effects and is using it to continue his studies on autism.
Lyn Redwood is a nurse practitioner and the former head of Children’s Health Defense, the anti-vaccine group founded by Mr. Kennedy. Since the early 2000s, Ms. Redwood has criticized the use of mercury as a preservative in vaccines. She has said she believes the ingredient is linked to her son’s autism.
Now listed as an expert at H.H.S., Ms. Redwood gave a presentation in June to the immunization committee, a role usually reserved for C.D.C. scientists. She said that the mercury preservative in vaccines, known as thimerosal, was toxic to children, even though dozens of studies have shown it is harmless in this form. The panel later voted to stop recommending the already limited number of flu vaccines that contained the preservative.
Principal deputy director of the N.I.H.
Skeptical of certain vaccines
N.I.H. director
Critical of Covid vaccine mandates
Dr. Matthew Memoli
Dr. Jay Bhattacharya
Dr. Matthew Memoli is a veteran infectious disease scientist at the National Institutes of Health who now serves as its principal deputy director. As a senior researcher under Dr. Anthony Fauci during the pandemic, Dr. Memoli opposed Covid vaccine mandates and declined to get a shot himself.
Since becoming a leader of the research agency, Dr. Memoli has downplayed the value of vaccines for certain respiratory diseases, according to the whistle-blower complaints of two prominent scientists.
Dr. Jay Bhattacharya, the N.I.H director, sharply criticized vaccine mandates as an academic researcher during the pandemic. He co-wrote an anti-lockdown treatise in 2020 with Dr. Kulldorff, one of Mr. Kennedy’s selections for the C.D.C. immunization committee.
During his confirmation hearing in March, Dr. Bhattacharya reiterated his support for childhood vaccinations for diseases like measles. He also said he was “convinced” vaccines did not cause autism, even as he urged more research on the question, which scientists say has long been settled.

Collagen supplements have exploded in popularity, touted as everything from an anti-aging miracle to a muscle recovery booster.
But a sweeping new review conducted by U.K. researchers suggests that while collagen may help improve skin elasticity and ease arthritis pain, it does little for athletic performance or wrinkle reduction.
Researchers from Anglia Ruskin University analyzed 16 systematic reviews and 113 randomized controlled trials involving nearly 8,000 participants worldwide, which they say is the most extensive evaluation of collagen’s health effects to date.
The review found consistent evidence that collagen supplementation improves skin elasticity and hydration over time and provides significant relief from osteoarthritis-related joint pain and stiffness, according to findings published in Aesthetic Surgery Journal Open Forum.

The researchers, however, did not find meaningful improvements in post-exercise muscle recovery, soreness or tendon mechanical properties (strength, springiness and stretch resistance).
“Collagen is not a cure-all, but it does have credible benefits when used consistently over time, particularly for skin and osteoarthritis,” co-author Lee Smith, professor of public health at Anglia Ruskin University, said in a statement.
EXPERIMENTAL SERUM SHOWS PROMISE IN REVERSING BALDNESS WITHIN 20 DAYS
“Our findings show clear benefits in key areas of healthy aging, while also dispelling some of the myths surrounding its use,” Smith added.
Collagen, the most abundant protein in the body, supports skin, bones, tendons, cartilage and connective tissue, according to experts. Natural collagen production begins to drop in early adulthood and declines more sharply with age.

The review found that long-term collagen supplementation was linked to improved skin firmness and hydration, but did not help skin roughness — a proxy for visible wrinkles.
Benefits appear to accumulate gradually, suggesting that collagen should not be viewed as an “anti-wrinkle ‘quick fix,’ but as a foundational dermal support for individuals seeking holistic skin maintenance,” the researchers said.
“If we define anti-aging as a product or technique designed to prevent the appearance of getting older, then I believe our findings do support this claim for some parameters,” Smith told the BBC. “For example, an improvement in skin tone and moisture is associated with a more youthful-looking appearance.”
Collagen supplementation was linked to reduced pain and stiffness in people with osteoarthritis, with stronger benefits seen over longer periods of use, and showed modest improvements in muscle mass and tendon structure that may support healthy aging.

However, it did not show meaningful results when used as a fast-acting sports performance supplement, and evidence for benefits related to cholesterol, blood sugar, blood pressure and oral health was mixed or inconclusive.
Dr. Daniel Ghiyam, a California-based physician and longevity specialist, said the findings align with what he sees in clinical practice.

“Collagen is a targeted support tool, not a foundation of health or performance,” Ghiyam, who was not involved in the study, told Fox News Digital. “When marketed that way, it makes sense. When marketed as a cure-all, it doesn’t hold up to the data.”
The authors noted that while many previous collagen studies have received financial support from the supplement industry, the current review did not receive industry funding.

The team called for more high-quality clinical trials examining long-term outcomes, optimal dosages and differences between collagen sources, such as marine, bovine and plant-based alternatives.
Among its limitations, the review could not determine whether certain forms of collagen work better than others or what the optimal regimen should be.

While the review included randomized controlled trials, the quality of the studies varied, with newer research generally showing stronger results.
Experts say more data and studies are needed to build on the findings. They also noted that diet plays a crucial role in skin health.

Dr. Erum Ilyas, a Pennsylvania-based dermatologist and chair of dermatology at Drexel University College of Medicine, noted that the review analyzed previously published meta-analyses rather than generating new primary data.

“At this time, I have not seen sufficiently strong independent evidence to routinely recommend collagen supplements to my patients,” Ilyas, who was not involved in the review, told Fox News Digital.
“Although some studies show modest improvements in markers such as hydration and elasticity, there remains limited independent, biopsy-confirmed evidence demonstrating sustained increases in dermal collagen content,” she added.
Fox News Digital has reached out to the researchers for comment.

As colorectal cancer (CRC) is now the leading cause of cancer death in adults under 50, a new report reveals some surprising shifts in the incidence of the disease.
Although rates of CRC have been declining among seniors, those 65 and under are facing a rise in diagnoses, according to a report titled Colorectal Cancer Statistics, 2026, from the American Cancer Society.
Adults 65 and younger comprise nearly half (45%) of all new colorectal cancer cases — a significant increase from 27% in 1995, states the report, which was published in CA: A Cancer Journal for Clinicians.
The disease is rising fastest among adults 20 to 49 years old, at a rate of 3% per year.

Among adults 50 and under, 75% of colorectal cancers are diagnosed at an advanced stage. Half of the diagnoses in that age range are made between the ages of 45 and 49. Although that age group is eligible to receive routine screenings, just 37% do so.

The report also revealed that rectal cancer is on the rise, now accounting for about one-third (32%) of all CRC cases — an increase from 27% in the mid-2000s.

“After decades of progress, the risk of dying from colorectal cancer is climbing in younger generations of men and women, confirming a real uptick in disease because of something we’re doing or some other exposure,” said Rebecca Siegel, senior scientific director, surveillance research at the American Cancer Society and lead author of the report, in a press release.

“We need to redouble research efforts to understand the cause, but also circumvent deaths through earlier detection by educating clinicians and the general public about symptoms and increasing screening in people 45-54 years.”
It is projected that 158,850 new cases of colorectal cancer will be diagnosed this year, and that the disease will cause 55,230 deaths, per the report.

More than half of CRC cases can be linked to high-risk behaviors, the researchers said. Those include lack of nutrition, high alcohol consumption, smoking, lack of exercise and obesity.
“These findings further underscore that colorectal cancer is worsening among younger generations and highlight the immediate need for eligible adults to begin screening at the recommended age of 45,” said Dr. William Dahut, chief scientific officer at the American Cancer Society.
When the disease is caught at a local (early) stage, the five-year survival rate is 95%. (iStock)
“The report also shines a light on the crucial importance of continued funding for research to help discover new therapies to treat the disease and advance patient care.”

A new study suggests that middle-aged men may be more vulnerable to faster biological aging, potentially linked to exposure to “forever chemicals.”
The research, published in the journal Frontiers in Aging, examined how perfluoroalkyl and polyfluoroalkyl substances, more commonly known as PFAS, could impact aging at the cellular level.
PFAS are synthetic chemicals commonly used in nonstick cookware, food packaging, water-resistant fabrics and other consumer products, the study noted.
Their chemical structure makes them highly resistant to breaking down, allowing them to accumulate in water, soil and the human body.
Chinese researchers analyzed blood samples from 326 adults enrolled in the U.S. National Health and Nutrition Examination Survey between 1999 and 2000.
A new study suggests that middle-aged men could face accelerated biological aging at the cellular level due to exposure to PFAS. (iStock)
The researchers measured levels of 11 PFAS compounds in participants’ blood and used DNA-based “epigenetic clocks” — tools that analyze chemical changes to DNA to estimate biological age — to determine how quickly their bodies were aging at the cellular level, the study stated.

Two compounds, perfluorononanoic acid (PFNA) and perfluorooctanesulfonamide (PFOSA), were detected in 95% of participants.
Higher concentrations of those chemicals were associated with faster biological aging in men of certain age groups, but not in women.
“People should not panic.”
The compounds most strongly linked to accelerated aging were not the PFAS chemicals that typically receive the most public attention, the researchers noted.

“The associations were strongest in adults aged 50 to 64, particularly in men,” Dr. Xiangwei Li, professor at Shanghai Jiao Tong University School of Medicine and the study’s corresponding author, told Fox News Digital.
“While this does not establish that PFAS cause aging, it suggests that these widely present ‘forever chemicals’ may be linked to molecular changes related to long-term health and aging.”
The study found that two of the compounds were detected in 95% of participants, and higher levels were linked to faster biological aging in men ages 50–64. (iStock)
Midlife may represent a more sensitive biological period, when the body becomes more vulnerable to age-related stressors, according to the researchers.
Lifestyle factors, such as smoking, may influence biological aging markers, potentially increasing vulnerability to environmental pollutants.
While Li said “people should not panic,” she does recommend looking for reasonable ways to reduce exposure.
That might mean checking local drinking water reports, using certified water filters designed to reduce PFAS, and limiting the use of stain- or grease-resistant products when alternatives are available.

Meaningful reductions in PFAS exposure will likely depend on broader regulatory action and environmental cleanup efforts, Li added.
The researchers noted that midlife could be a particularly sensitive stage, when the body is more susceptible to stressors associated with aging. (iStock)
Study limitations
The researchers outlined several important limitations of the research, including that the findings show an association, but do not prove that PFAS directly causes accelerated aging.
“The study is cross-sectional, meaning exposure and aging markers were measured at the same time, so we cannot determine causality,” Li told Fox News Digital.
The study was also relatively small, limited to 326 adults age 50 or older, which means the findings may not apply to younger people or broader populations.

Researchers measured PFAS levels using data collected between 1999 and 2000, and today’s exposure patterns may differ.
Li added that while PFAS is known to persist in the environment and the body, these results should be validated through larger, more recent studies that follow participants over time.
