Trump Administration Requests Pause in Lawsuit Over Vaccine Guidance Changes

Administration lawyers stated in the filing that they are still evaluating whether to appeal a March ruling that blocked the updates. The motion argues that pausing the case would promote judicial economy and avoid unnecessary burdens on government agencies.

Background on the Ruling In March, a federal judge stayed the updates to CDC vaccine guidance implemented under Health Secretary Robert F. Kennedy Jr. The ruling reverted the guidance to its mid-2025 version. The judge determined that officials did not follow proper procedures in updating the guidance and appointing new members to the CDC's vaccine advisory committee.

The stay would remain in effect if the requested pause is approved, according to administration lawyers. They noted that if an appeal is filed, the U.S. Court of Appeals for the First Circuit might dismiss some or all claims, potentially eliminating the need for record production.

The lawyers requested the proceedings be stayed until May 15 or the resolution of any appeal, whichever comes later. May 15 is the deadline to appeal the preliminary injunction. The Department of Health and Human Services previously stated it would prevail in an appeal but has not yet filed one.

A department spokesperson said that unless officially announced, assertions about next steps are baseless speculation.

The lawsuit was initiated by multiple health care groups, including the American Academy of Pediatrics. Government lawyers conferred with the plaintiffs, who opposed the motion to pause proceedings. The filing highlighted that a decision from the appeals court could narrow disputed issues and guide resolution of remaining matters.

It also warned of potential wasted resources if proceedings continue before the appeal deadline.
