Health Secretary Robert F. Kennedy Jr.’s Vaccine Policy Overhaul and the Growing Legal Fight

Since taking office, Health Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic, has pursued a sweeping re-examination of U.S. immunization policy. Early in his tenure he dismissed all 17 members of the Advisory Committee on Immunization Practices (ACIP) and appointed new panelists who share his skepticism. The reshaped ACIP subsequently rescinded several longstanding childhood-vaccine recommendations and, in January, announced a new schedule that cut the number of routinely recommended diseases from 18 to 11.

• ACIP Reconstitution – Kennedy’s hand-picked appointments replaced the prior expert panel, prompting the CDC to drop universal recommendations for hepatitis A, hepatitis B, RSV, dengue and two bacterial-meningitis vaccines.

The Hill

• Childhood Schedule Reduction – The revised schedule eliminates routine shots for several diseases, a move the lawsuit alleges was “arbitrarily and capriciously” adopted without scientific justification.

Medical groups led by the American Academy of Pediatrics filed suit alleging violations of the Administrative Procedure Act. A district court in Massachusetts issued a preliminary injunction blocking the new schedule and pausing ACIP’s actions, finding that Kennedy “unlawfully” replaced members with “distinctly unqualified” individuals.

The Department of Health and Human Services appealed the injunction. On the First Circuit, Justice Department attorney Matthew Zorn argued that the district court exceeded its authority and that the stay functions as an injunction, raising questions about appellate jurisdiction. Chief Judge David Barron asked whether the court had proper jurisdiction, noting the stay’s practical effect as an injunction.

The plaintiffs contend that the stay is appropriate because the reconstituted ACIP cannot fulfill its core responsibilities, while the government maintains that the district court’s order does not constitute a final agency action subject to review.

Medical organizations argue that altering vaccine recommendations without robust scientific evidence could lower coverage, increase hesitancy, and raise the risk of preventable disease outbreaks.

• Pennsylvania’s recent measles outbreak surpassed 1,000 cases, with roughly one-third occurring in individuals under 18, illustrating potential consequences of reduced vaccine coverage.

The Hill

• Jurisdiction Question – The DOJ argues the stay is an injunction subject to appellate review; the plaintiffs assert the district court’s order is not a final agency action and therefore outside the appellate court’s purview.

• Scope of Injunction – While the district court blocked ACIP’s actions, the administration seeks to lift the stay to allow the reconstituted panel to issue recommendations ahead of the flu season. The precise legal standard for “final agency action” remains unsettled.

• “The secretary wants to get the ACIP back to work, and we are being told if he reconstitutes any committee, it’s going to be right back in court,” — Matthew Zorn, Justice Department attorney

• “There’s the question of whether we have appellate jurisdiction because the stay has the practical effect of being an injunction,” — Chief Judge David Barron

The First Circuit is scheduled to hear oral arguments on the appeal, with both sides expected to press their jurisdictional arguments. A decision could determine whether the reconstituted ACIP may resume work before the upcoming flu season and shape the future of federal vaccine policy.
