Deep Look
Robert F. Kennedy Jr., long known for his controversial views on vaccines, has secured the political support needed to become the nation’s top health official. But in doing so, his administration has already begun to disrupt long-standing protocols in vaccine approval and public health guidance—causing unease among experts and vaccine developers alike.
Kennedy, who has pledged to “work within the system,” now leads an administration that is preparing a comprehensive overhaul of how the U.S. evaluates, approves, and distributes vaccines. According to FDA Commissioner Marty Makary, a new framework for vaccine regulation will soon be “unleashed,” though few specifics have been made public. What is clear, however, is that the change is being shaped by individuals who have openly criticized the very agencies they now run.
Dr. Vinay Prasad, recently appointed as the FDA’s new vaccine chief, has a track record of questioning the benefits of COVID-19 booster shots, particularly for low-risk populations. He, along with Makary and Dr. Tracy Beth Hoeg, are now key players in rewriting U.S. vaccine strategy after having spent much of the pandemic criticizing it. The shift has already impacted vaccine policy in tangible ways.
FDA Vaccine Overhaul Already Delaying Approvals
One of the first major signs of change came with the delay of Novavax’s COVID-19 booster shot. FDA scientists were set to approve it in early spring, but the decision was postponed after senior administration officials demanded additional scrutiny. When approval did finally come, it was limited to people at higher risk from COVID-19—a restriction that surprised many observers. The administration also insisted Novavax conduct a post-approval clinical trial, an unusual requirement for an already-reviewed product.
Insiders revealed that Hoeg, a political appointee and special assistant to Makary, was instrumental in demanding new data from Novavax. These delays and restrictions come as the FDA prepares for a key meeting where vaccine advisers will debate updates to COVID-19 shots ahead of the 2025 fall-winter season.
Such decisions appear to shift power from long-standing FDA scientists to political appointees, a change that many in the medical community find troubling. Historically, the FDA’s credibility has hinged on the independence of its scientific decisions. Under Kennedy’s leadership, that dynamic is being questioned.
CDC and NIH Face Vaccine Messaging Uncertainty
The FDA isn’t the only agency experiencing transformation. The CDC has not yet responded to recent advisory panel recommendations on new meningitis and RSV vaccines. A meeting of Kennedy’s “Make America Healthy Again” coalition reportedly signaled an end to COVID-19 booster recommendations for children—though no formal decision has been made.
Meanwhile, the National Institutes of Health has reduced or withdrawn funding for research projects related to vaccine hesitancy. The timing has raised alarms, particularly as misinformation continues to thrive online and public confidence in vaccines remains fragile post-pandemic.
Dr. Amesh Adalja, an infectious disease expert at Johns Hopkins, voiced concern that Kennedy’s health agenda might deliberately make vaccine approvals more difficult. “You have to assume RFK Jr.’s intention is to make it harder for vaccines to come to market,” Adalja said. “This is someone with a proven record of questioning vaccine value.”
False Claims and Misinformation Undermining Trust
Adding to scientific apprehension, Kennedy recently made inaccurate claims in a Senate hearing. He asserted that only COVID-19 vaccines had ever been tested using a placebo, which was quickly corrected by Sen. Bill Cassidy, who cited placebo-controlled trials for vaccines against rotavirus, measles, and HPV.
In response to such rhetoric, a group of doctors compiled an extensive list of over 120 vaccine clinical trials conducted over the past several decades, many of which used saline placebos. Dr. Jake Scott, an infectious disease physician at Stanford who helped lead the project, stated, “It directly debunks the claim that vaccines were never tested against placebo.”
Scott explained that in some trials, substances other than saline are used to maintain the “blinded” integrity of the study, especially when symptoms like injection site pain could reveal who received the vaccine. In cases where an effective vaccine already exists, ethics prohibit giving a placebo to new trial participants, further complicating the public narrative.
“We can’t always expect placebo-controlled trials,” Scott said. “That must be communicated to the public clearly, despite misinformation and noise on social media.”
Industry and Experts Push Back
As regulatory uncertainty grows, vaccine manufacturers are already adjusting their timelines. Moderna, for example, announced delays in its COVID-and-flu combination shot due to new data requests from the FDA. The company now aims for a 2026 release.
Dr. Jesse Goodman, a former FDA vaccine director, warned that constantly demanding new trials could prevent timely vaccine rollouts. “You’d always be doing clinical trials and never have a vaccine that’s up to date,” he said, referencing the annual race to prepare COVID-19 vaccines for seasonal surges.
Dr. Michael Osterholm, a respected infectious disease expert at the University of Minnesota, emphasized that annual boosters continue to reduce hospitalizations among seniors, even if the data aren’t perfect. “The data are clear and compelling,” he said, calling attempts to diminish their benefit misguided.
Prasad, meanwhile, has called for new randomized studies on booster effectiveness in older adults, casting doubt on annual recommendations. Yet experts like Adalja maintain that the CDC’s Advisory Committee on Immunization Practices is the proper body to evaluate such questions—not politically appointed FDA officials.
Conclusion: Public Health at a Crossroads
The Kennedy administration’s aggressive reshaping of vaccine policy reflects a deep mistrust of traditional public health structures. Supporters see the changes as a move toward more transparency and caution. Critics fear a rollback of hard-won scientific progress and a weakening of the nation’s ability to respond quickly to emerging threats.
As the FDA prepares to debate fall 2025 vaccine updates, and as global health organizations watch closely, one thing is certain: vaccine science is now as much a political issue as it is a public health one.
