Leading Medical Experts Applaud Court Ruling to Block Federal Vaccine Changes

A major federal court ruling has paused sweeping changes to U.S. vaccine policy, prompting swift response from physicians, public health leaders, and medical organizations nationwide.

The lawsuit – brought by the American Academy of Pediatrics and other groups – challenges recent actions by the Department of Health and Human Services to alter the childhood vaccination schedule and restructure the Advisory Committee on Immunization Practices (ACIP), arguing the changes violate longstanding legal and scientific processes.

By blocking these actions while litigation continues, the court’s decision creates a critical pause in what many experts have described as a destabilizing shift in vaccine governance. At the same time, the ruling raises urgent questions about the future of the committee. The U.S. relies on a fully functioning, independent ACIP to deliver clear, science-based guidance that providers, insurers, and patients can trust.

Across the board, responding organizations underscore a common concern: Disruptions to scientific expertise, transparency, and established processes erode trust and carry real consequences for public health. Protecting access requires safeguarding the integrity of the systems that guide vaccine policy.

Below is a roundup of statements from leading organizations, with links to their full responses. The Partnership to Fight Infectious Disease statement is available here.

The American Academy of Pediatrics emphasized the broader significance of the judge’s decision:

“This decision effectively means that a science-based process for developing immunization recommendations is not to be trifled with and represents a critical step to restoring scientific decision-making to federal vaccine policy that has kept children healthy for years.”

The American College of Physicians framed the ruling as a reaffirmation of core principles:

“Today's ruling is a win for public health and reaffirms that national vaccine policy should be guided by rigorous, evidence-based science, not politics. Vaccines are critical to maintaining public health. … Scientific consensus and overwhelming evidence demonstrate that vaccines are safe and effective.”

The American Public Health Association highlighted the importance of transparency:

“This injunction underscores the need for using science in public health decision-making and using a process that engages qualified experts. … Trust occurs when we engage the public in a transparent process, not one where decisions are made behind closed doors by unqualified individuals and presented in a disingenuous way.”

The Association for Professionals in Infection Control and Epidemiology (APIC) and the Society for Healthcare Epidemiology of America (SHEA), expressed their support for the ruling:

“The outcome of this lawsuit … will restore clarity and stability to the U.S. vaccine recommendation process. The underlying science, research, and manufacturing that support vaccines have not changed, and childhood vaccinations continue to play an important role in protecting the health and safety of children, families, and communities.”

The Infectious Diseases Society of America warned of the real-world consequences of undermining established systems:

“Today's court ruling is an important step toward protecting Americans' access to life-saving vaccines. … Secretary Kennedy has caused needless confusion and distrust in vaccine guidance and unless stopped, his actions will continue to result in preventable disease outbreaks.”

The Massachusetts Public Health Alliance warned of long-term fallout:

“This decision [pauses] the implementation of a childhood vaccination schedule that could undermine years of progress in saving our nation's children from illness, suffering, and even death. … people's health and lives are at risk and we are committed to promoting public health.”

The Society for Maternal-Fetal Medicine emphasized the stakes for pregnant patients and newborns:

“We welcome today's court decision. … As maternal-fetal medicine specialists caring for high-risk pregnancies, our highest priority is protecting pregnant patients, their infants, and families from vaccine-preventable illness and death—guided by rigorous science, transparent evidence, and clinical best practices.”
