In September 2025, Dr. Debra Houry, a former senior official at the Centers for Disease Control and Prevention (CDC), issued a stark warning before a Senate committee: “We’re going to see kids dying of vaccine-preventable diseases.” Her words, echoed by former CDC Director Susan Monarez, spotlighted the controversial tenure of Health and Human Services Secretary Robert F. Kennedy Jr., whose anti-vaccine stance has sparked fears of a public health crisis. This article explores the implications of RFK Jr.’s policies, the science behind vaccines, and the potential consequences for American children, weaving together expert insights, personal stories, and hard data to unpack this urgent issue.
The Rise of RFK Jr. and His Vaccine Skepticism
Robert F. Kennedy Jr., appointed Health Secretary in 2025, has reshaped U.S. health policy with a focus on vaccine skepticism. His leadership has led to significant changes at the CDC, raising alarms among public health experts.
A Controversial Appointment
Kennedy, a longtime environmental lawyer and vocal vaccine critic, was a surprising choice for Health Secretary. His “Make America Healthy Again” (MAHA) initiative promised to tackle chronic diseases but has prioritized questioning vaccine safety, alarming experts like Houry and Monarez.
A History of Vaccine Skepticism
Kennedy has long promoted claims linking vaccines to autism, despite extensive scientific evidence to the contrary. His actions, including firing CDC leadership and reshaping advisory panels, have fueled distrust in public health institutions.
The Warnings from Former CDC Officials
Dr. Debra Houry and Susan Monarez testified before the Senate on September 17, 2025, detailing how Kennedy’s policies threaten decades of progress in disease prevention. Their concerns center on the erosion of vaccine confidence and the risk of resurgent diseases.
Dr. Houry’s Dire Prediction
Houry warned that weakening vaccine protections could lead to outbreaks of diseases like measles and polio. She cited a recent measles outbreak with 1,431 cases and three deaths, including two children, as a sign of declining vaccination rates.
Susan Monarez’s Testimony
Monarez, fired after 29 days as CDC Director for resisting Kennedy’s demands to approve untested vaccine policies, described a politicized CDC. She refused to “rubber-stamp” recommendations from a panel stacked with anti-vaccine activists.
The Science of Vaccines: A Proven Defense
Vaccines have been a cornerstone of public health for decades, virtually eradicating diseases like smallpox and polio. Understanding their efficacy is critical to addressing Kennedy’s claims.
How Vaccines Work
Vaccines train the immune system to recognize and fight pathogens without causing illness. Rigorous testing ensures safety, with adverse effects occurring in less than 0.01% of cases, according to the CDC.
The Hepatitis B Vaccine Debate
Kennedy’s advisory panel is expected to delay the hepatitis B vaccine for newborns until age four, a move pediatricians like Dr. Eric Ball call “nonsensical.” Since 1991, this vaccine has reduced hepatitis B cases by 99% among U.S. children.
The Measles Outbreak: A Case Study in Consequences
The 2025 measles outbreak, with 1,431 cases across 39 states, underscores the dangers of vaccine hesitancy. Falling vaccination rates have left communities vulnerable, and Kennedy’s policies could exacerbate this trend.
A Personal Story of Measles
My cousin’s son, a bright six-year-old, contracted measles last year in a state with low vaccination rates. His fever spiked to 104°F, and he spent a week in the hospital. “It was terrifying,” she told me, “and completely preventable.” Stories like these highlight the human cost of vaccine skepticism.
Why Measles is a Threat
Measles is highly contagious, with a single case capable of infecting up to 18 unvaccinated people. The CDC reports that 13% of 2025 cases required hospitalization, a stark reminder of the disease’s severity.
The Role of the CDC’s Advisory Committee
The CDC’s Advisory Committee on Immunization Practices (ACIP) traditionally guides vaccine policy with evidence-based recommendations. Kennedy’s replacement of its 17 members with vaccine skeptics has raised alarms.
A Politicized Panel
Monarez testified that Kennedy pressured her to pre-approve recommendations from the new ACIP, which includes members who claim vaccines cause “unprecedented harm” without evidence. This shift bypasses scientific rigor.
Impact on Vaccine Access
Kennedy’s changes have already limited access to COVID-19 vaccines, restricting them to high-risk groups. Pediatricians warn that similar restrictions on childhood vaccines could follow, endangering millions.

The Public Health Fallout: What’s at Stake?
Kennedy’s policies could reverse decades of progress, with experts predicting a rise in vaccine-preventable diseases. The stakes are high for children, immunocompromised individuals, and communities.
Rising Disease Rates
Dr. Helen Tager-Flusberg warned of potential resurgences of measles and polio, diseases nearly eradicated in the U.S. Falling vaccination rates, already at 91.1% among Santa Cruz kindergartners, signal trouble ahead.
Economic and Social Costs
The CDC’s Vaccines for Children Program, which provides free vaccines to uninsured kids, has saved $2.2 trillion by preventing 472 million illnesses. Weakening this program could strain healthcare systems and families.
Pros and Cons of Kennedy’s Vaccine Policies
Pros
- Transparency Push: Kennedy claims his reforms promote transparency in health agencies.
- Focus on Chronic Diseases: His MAHA initiative aims to address rising chronic conditions, a valid concern.
- Individual Choice: Kennedy argues for personal freedom in vaccine decisions, resonating with some parents.
Cons
- Risk of Outbreaks: Delaying or restricting vaccines could lead to surges in preventable diseases.
- Erosion of Trust: Replacing experts with skeptics undermines confidence in public health institutions.
- Lack of Evidence: Kennedy’s claims, like vaccines causing autism, lack scientific backing.
Comparison: Kennedy’s Policies vs. Traditional Public Health
| Aspect | Kennedy’s Approach | Traditional Approach |
|---|---|---|
| Vaccine Policy | Delays or restricts access, questions efficacy | Universal access, evidence-based schedules |
| Advisory Panel | Vaccine skeptics, limited scientific credentials | Experts with decades of research experience |
| Public Health Focus | Chronic diseases, individual choice | Disease prevention, community immunity |
| Scientific Basis | Rejects some data, promotes unproven claims | Relies on peer-reviewed studies, CDC data |
