This page is a press release from Japan's Ministry of Health, Labour and Welfare dated August 29, 2021, regarding the suspension of some batches of Moderna COVID-19 vaccine in Okinawa Prefecture. Foreign particles were discovered in vaccine vials and syringes. Investigation by Takeda Pharmaceutical confirmed that particles were introduced during needle puncture, specifically from rubber stopper coring, and were not present before puncture. The vaccine batch quality is deemed acceptable with no safety concerns. The ministry continues to advise visual inspection of vials before use.
