NHK reported that following the discovery of foreign substances in some unused vials of the Moderna vaccine, the Health Ministry has been contacting 863 vaccination sites across Japan that have received vials of the vaccine manufactured in the same factory as the contaminated ones to ask them to suspend the use of those vials. According to the network, the vials in question were manufactured in a factory in Spain and shipped to Japan starting in late July. Although the ministry did not disclose the names of the vaccination centers that have been affected, they include large-scale vaccination centers operated by local municipalities and workplace vaccination sites. The ministry is planning to send replacement vaccines to the vaccination sites to minimize the impact on Japan’s vaccination rollout. The network added that Takeda Pharmaceutical, which handles the distribution of Moderna vaccines in Japan, has asked the U.S. company to identify the foreign substances and explain how the vials were contaminated.
