IDSA and our co-plaintiffs recently made positive progress in the legal challenge to Health and Human Services Secretary Kennedy’s unilateral and unlawful changes to vaccine policy. Calling the case one of national importance, the judge in the U.S. District Court in the District of Massachusetts ruled Oct. 30 in favor of our motion requesting that this case move forward promptly despite the federal government shutdown. A December hearing is expected on the government’s motion to dismiss the case. Assuming IDSA and our co-plaintiffs defeat that motion, a trial is expected in early 2026.
IDSA is deeply grateful to the members who have shared their valuable time and expertise to inform the arguments in this case and who have signed declarations to contribute to this case.
This case is part of IDSA’s broader strategy to protect patients’ access to vaccines and other evidence-based care and services to prevent, diagnose and treat infectious diseases. Our Society will continue to stand up for science, our members and the patients and communities they serve.
