Why the World Is Watching RFK Jr.’s Fight with the CDC
Kennedy’s clash with America’s top health agency is reshaping vaccine policy, public health, and pandemic preparedness—with global consequences at stake
By Rana Raheel
Robert F. Kennedy Jr. has always been a polarizing figure in the world of health policy. Now, as the US Health Secretary, his showdown with the Centers for Disease Control and Prevention (CDC) is making headlines not only in America but across the globe.
Earlier this week, Kennedy appeared before the Senate after abruptly firing the CDC’s new director, Susan Monarez—only 29 days into her role. The move shocked Washington, triggered mass resignations inside the CDC, and raised urgent questions about the future of US public health.
When asked to explain, Kennedy claimed he had asked Monarez if she was “trustworthy,” and she allegedly said “no.” Critics were baffled, but Kennedy doubled down, calling the CDC “the most corrupt agency in government” and promising even more sweeping changes.
For many scientists and doctors, the concern isn’t just about political drama—it’s about what these shake-ups mean for vaccines, disease prevention, and America’s readiness for the next health crisis. Our health policy tracking tools can help you monitor these developments in real-time.
Timeline of Crisis
How we got to this unprecedented moment in US public health
RFK Jr. Takes Office as Health Secretary
Kennedy assumes control of the Department of Health and Human Services, immediately signaling major changes ahead for public health agencies.
Vaccine Advisory Panel Fired
Kennedy dismisses all 17 members of the CDC’s vaccine advisory committee (ACIP), citing “conflicts of interest” and appoints his own handpicked panel.
David Geier Appointed
Kennedy brings in vaccine critic David Geier to re-examine CDC vaccine data, raising concerns among public health experts about scientific integrity.
CDC Director Fired After 29 Days
Susan Monarez is abruptly dismissed, triggering mass resignations and a Senate hearing that captivated the nation.
Kennedy’s Long-Running Vaccine Controversy
Kennedy’s skepticism toward vaccines is nothing new. For eight years, he ran Children’s Health Defense, an organization that repeatedly questioned vaccine safety. He has labeled the Covid-19 vaccine “the most deadly in history” and pushed the widely debunked idea that vaccines are linked to autism. Learn more about evidence-based health practices on our site.
“I lost my job, but America’s children could lose far more.”
— Susan Monarez, Former CDC Director, in her op-ed
So when he took office earlier this year, public health experts braced for impact. Their fears grew when Kennedy appointed David Geier, a known vaccine critic, to re-examine CDC vaccine data. Then came the bombshell: Kennedy fired the entire CDC vaccine advisory panel (ACIP), accusing its 17 members of being riddled with “conflicts of interest.”
He replaced them with a new, handpicked panel—sparking concern that US vaccine guidance could be reshaped by politics rather than science.
That decision soon collided with Monarez’s leadership. In an op-ed, she claimed Kennedy demanded that she “pre-approve” the new panel’s recommendations, which she refused. Kennedy, however, insists her account is false and says her firing was “absolutely necessary.”
CDC in Crisis
A mass exodus of America’s top health experts
Monarez’s removal wasn’t an isolated event. In recent months, the CDC has seen a mass exodus of its top experts, including its chief medical officer, director of immunization, and head of emerging diseases. Track these changes with our CDC Leadership Monitor tool.

Global Health Community Responds
The upheaval at the CDC isn’t just an American problem—it’s sending shockwaves through the global health community. The CDC has long been considered the world’s premier disease surveillance and response agency, and its guidance influences health policies from London to Lagos. Explore our comprehensive health policy analysis for more insights.
🇪🇺 European Response
The European Centre for Disease Prevention and Control (ECDC) has quietly begun developing independent vaccine guidance, no longer automatically following CDC recommendations.
🇨🇦 Canadian Concerns
Health Canada announced it will “carefully evaluate” any new CDC guidance before adopting it, marking a significant shift in the traditionally close relationship.
🌍 WHO Statement
The World Health Organization expressed “concern” about changes to US vaccine policy and emphasized the importance of “evidence-based decision making.”
🏥 Medical Journals
The Lancet, NEJM, and JAMA published a rare joint editorial calling for “scientific integrity” in public health decision-making.
“When the CDC sneezes, the world catches a cold. These changes could undermine global vaccine confidence at the worst possible time.”
— Dr. Maria Santos, Former WHO Deputy Director-General

What Happens Next?
The coming months will be crucial for determining whether Kennedy’s vision for public health reform will succeed or whether the disruption will cause lasting damage to America’s health infrastructure.
📊 Congressional Oversight
Senate hearings are scheduled for next month to examine the CDC’s leadership crisis and its impact on public health preparedness.
🔬 Scientific Community Response
Medical associations are mobilizing to maintain evidence-based vaccine recommendations, potentially creating parallel guidance systems.
🌍 International Realignment
Other countries are developing independent health policies, potentially ending decades of CDC leadership in global health.
⚖️ Legal Challenges
Multiple lawsuits are expected challenging Kennedy’s authority to reshape vaccine policy without proper scientific review.
“For my own integrity as a scientist, I did not feel I could continue to serve when it felt like the data we were putting together was not going to be used in a science-based way.”
— Dr. Fiona Havers, Respected vaccine researcher who resigned in June
Dr. Fiona Havers, a respected vaccine researcher who resigned in June, explained her departure bluntly with these words. The departures have left the CDC weakened, just as Kennedy ramps up criticism of its Covid-era policies on masks, social distancing, and vaccine effectiveness. Read more about science-backed health practices that actually work.
🚨 Critical Capabilities at Risk
The stakes go far beyond Washington politics. For decades, the CDC has been a cornerstone of global health, helping track outbreaks, contain epidemics, and lead international responses.
Historical CDC Global Impact:
In 2015, for example, the CDC sent 3,000 staff to fight Ebola in West Africa, with 1,200 working on the ground—demonstrating America’s leadership in global health emergencies.
Global Health at a Crossroads
Now, experts fear those capabilities are being eroded. The implications extend far beyond American borders, potentially affecting global pandemic preparedness and international health cooperation.
⚠️ Expert Warnings
“What happens in America is of great importance. If science gets pushed aside for politics, not only the US but the whole world could pay the price.”
— Anthony Costello, Former WHO Director
🌍 Pandemic Preparedness
“Taking a sledgehammer to the CDC has left the US much less prepared for another pandemic—and that has huge global implications.”
— Dr. Fiona Havers, Former CDC Researcher
The Critical September 18 Meeting
All eyes are now on September 18, when the CDC’s new vaccine advisory panel meets for the first time. The panel will review recommendations on Covid, hepatitis B, and RSV vaccines—decisions that will directly affect millions of Americans and send a signal to the world about the future of US vaccine policy.

- • Global influence: How will other countries respond to new US guidance?
- • Public trust: Will Americans continue to trust vaccine recommendations?
- • Healthcare costs: Could policy changes increase preventable diseases?
Kennedy Doubles Down
Meanwhile, Kennedy shows no sign of backing down from his aggressive reform agenda. His message to senators was clear and uncompromising.
“We need bold, competent, and creative new leadership at the CDC. I need to fire some of those people and make sure this doesn’t happen again.”
— Robert F. Kennedy Jr., US Health Secretary
