On Saturday, March 21, 2026, Just The News reported that a federal judge in Massachusetts is facing increased scrutiny from the Trump administration and conservative commentators following a decision to block changes to federal vaccine policy. The ruling has brought renewed attention to the judge’s broader record on high-profile cases.
U.S. District Judge Brian E. Murphy issued a preliminary injunction halting the implementation of revisions to the childhood immunization schedule, which were announced in January 2026 by the Department of Health and Human Services under Secretary Robert F. Kennedy Jr. The changes aimed to reduce the number of routinely recommended childhood vaccines. Murphy also paused new appointments to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP), a key body that shapes federal vaccine recommendations.
In his 45-page ruling, Murphy stated that the reconstitution of ACIP likely violates federal law, including the Federal Advisory Committee Act’s requirements for balanced membership and relevant expertise, as well as procedural requirements under the Administrative Procedure Act. He also stayed all prior votes taken by the reconstituted panel and postponed an upcoming ACIP meeting.
Public health groups, including the American Academy of Pediatrics, have argued that the Trump administration’s changes bypassed established scientific processes and could undermine public confidence in vaccines. Murphy’s decision sided with these concerns. The administration has vowed to appeal the preliminary injunction, with an HHS spokesperson expressing confidence in eventual success.
Appointed to the U.S. District Court for the District of Massachusetts in 2024 by President Joe Biden, Judge Murphy has presided over several high-profile challenges to Trump administration policies across immigration, health, research funding, and energy sectors. Several of his high-profile rulings have been reversed on appeal, including by the Supreme Court.
One notable example involves the administration’s “third-country” deportation policy, which permits expedited removal of certain migrants to nations other than their origin countries without ties or full due process protections. Murphy has repeatedly blocked aspects of this policy. The Supreme Court intervened twice in the litigation, first with a 6-3 emergency stay allowing deportations to proceed in specific cases, and later with a 7-2 order, with Justice Elena Kagan joining conservatives in admonishing Murphy for flouting the high court’s earlier decision.
On the same day as the vaccine ruling, the U.S. Court of Appeals for the First Circuit paused Murphy’s latest block on third-country deportations, allowing the policy to continue during appeals. The Justice Department and allies quickly condemned Murphy’s vaccine decision. Deputy Attorney General Todd Blanche posted on X shortly after the ruling, questioning how many times Judge Murphy can be reversed in one year and accusing him of issuing another activist decision.
An HHS spokesperson stated that the department expects to appeal the vaccine ruling and expressed confidence that it will ultimately prevail. Groups aligned with Kennedy’s Make America Healthy Again movement characterized the decision as judicial overreach.
Judge Murphy is not alone among federal judges facing backlash from conservatives for rulings against Trump policies. Other judges, such as Judge James Boasberg and District Judge Tanya Chutkan, have also faced scrutiny for their rulings and handling of cases related to the Trump administration and the January 6 attack on the U.S. Capitol.
