During the hearing, government attorney Isaac Belfer argued that the Secretary of Health has wide discretion in interpreting public health laws and shaping vaccination guidance. In the course of the discussion, a hypothetical example was raised: whether the secretary could even encourage people to deliberately contract measles instead of getting vaccinated. When the judge asked whether such a decision would fall outside the court’s authority to review, the lawyer answered yes.
The hearing is part of a case brought by medical organizations, including the American Academy of Pediatrics, which are attempting to block changes to vaccination policy introduced under Kennedy’s administration. Critics argue that decisions such as reducing the number of recommended childhood vaccines and modifying the federal vaccination schedule lack sufficient scientific justification and could threaten public health.
Judge Brian Murphy expressed skepticism toward the government’s argument that the health secretary’s actions should not be subject to judicial oversight. During the hearing, he questioned whether courts truly lack the authority to review whether federal agencies act lawfully and in accordance with administrative rules when changing health policy.
The case is unfolding amid a broader debate in the United States about vaccination policy and the role of federal public health institutions. Robert F. Kennedy Jr., who has led the Department of Health and Human Services since 2025, has long been one of the most prominent critics of vaccination programs, a stance that has drawn strong opposition from many in the medical community.
The judge indicated that a decision on the request to block the vaccination policy changes could be issued before the next meeting of the federal advisory committee on vaccines, scheduled for mid-March. The outcome may determine how far the health secretary’s authority extends in shaping national vaccination policy.
