The public dismissal decision identifies J.D. as a minor but does not state the child's exact age.\n\nRespondent advised in October 2024 that the case was not appropriate for compensation and later filed a Rule 4(c) report defending against the claim. Chief Special Master Brian H. Corcoran ordered petitioner to file an expert report addressing causation. After several extensions, petitioner moved to dismiss, stating that she had been unable to locate an expert to support the claim.\n\nOn September 22, 2025, Chief Special Master Corcoran dismissed the petition with prejudice. The decision explains that without expert support or other reliable causation evidence, petitioner could not meet the Vaccine Act burden of proof. No compensation was awarded. Petitioner was represented by Richard Gage.","is_minor_inferred":1,"is_pediatric_broad":1,"special_master":"Thomas L.
