A federal judge on Monday blocked significant portions of Health Secretary Robert F. Kennedy Jr.'s effort to revise U.S. vaccine policy, including a plan to cut the number of childhood vaccinations routinely recommended. U.S. District Judge Brian Murphy in Boston granted relief to a coalition led by the American Academy of Pediatrics and other medical groups, which had sued federal health regulators.
The medical organizations argued the agencies acted unlawfully in implementing what they described as an agenda to upend established immunization practices. In their filings, the plaintiffs warned that the policy shifts would lead to lower vaccination rates and pose risks to public health.
Judge Murphy, who was appointed by President Joe Biden, sided with the plaintiffs in the challenge. The judge has previously drawn criticism from Republican President Donald Trump and his allies for blocking portions of the prior administration’s initiatives, including core elements of its stringent immigration policies.
The lawsuit contested actions taken by the U.S. Centers for Disease Control and Prevention. On January 5, the CDC reduced the number of routinely recommended childhood vaccinations to 11 and downgraded its recommendations for six diseases, naming rotavirus, influenza and hepatitis A among them. Those changes were central to the plaintiffs’ claim that the agency exceeded its lawful authority.
The legal challenge also targeted Kennedy’s personnel decisions affecting the Advisory Committee on Immunization Practices, or ACIP. Plaintiffs disputed Kennedy’s move last year to remove and replace all 17 independent experts who previously served on ACIP, the panel whose guidance shapes vaccine policy and influences insurance coverage in the United States.
The broader reaction to Kennedy’s policy shifts has been visible in clinical settings and state capitols. Pediatricians are reporting more parents expressing skepticism about vaccines and other medical treatments. Nearly a dozen states have begun considering legislative changes that would relax vaccine requirements for school enrollment, reflecting the ripple effects of the federal policy changes.
Major vaccine manufacturers have expressed growing wariness about the direction of U.S. vaccine policy. Companies producing mRNA COVID-19 vaccines include Pfizer, BioNTech and Moderna, while firms that make other vaccines on the childhood schedule include Merck, Sanofi and GSK. The legal ruling and the unfolding policy debates may affect how vaccine makers and clinicians engage with the U.S. immunization framework.
Summary: A Boston federal judge blocked key parts of Health Secretary Robert F. Kennedy Jr.'s revisions to childhood vaccine recommendations, granting plaintiffs' claims that regulators acted unlawfully and noting public health concerns tied to lower vaccination rates.
