Foreign bodies were found in five unused vials of Pfizer Inc.’s COVID-19 vaccine in two cities near Tokyo and one in Osaka Prefecture, local governments said on Tuesday.
The vials containing the floating white matter belong to the same batch, FF5357, according to the cities of Sagamihara and Kamakura, both in Kanagawa Prefecture, and Sakai in western Japan.

All three cities have asked Pfizer to analyze the substances.
The contaminants were discovered at three vaccination sites in Sagamihara between Saturday and Tuesday, one site in Kamakura on Sunday and one site in Sakai on Tuesday.
Cities said they did not use doses containing the foreign matter while continuing to administer doses with the same lot number that were confirmed to be uncontaminated.
Last month, the Department of Health halted the use of approximately 1.63 million doses of Moderna Inc.’s COVID-19 vaccine as a precautionary measure after the discovery of foreign substances in many vials.
