Japan Halts Use of 1.6 Million Moderna Shots on Contamination Reports

Japan Halts Use of 1.6 Million Moderna Shots on Debris Reports

Japan suspended the use of 1.63 million doses of Moderna Inc.’s Covid-19 vaccine after receiving reports of foreign particles in the vials from several vaccination sites.

Takeda Pharmaceutical Co Ltd., which is the local distributor of the vaccine, and Japan’s health ministry agreed to stop using doses from three lots after discussing the matter, they said in separate statements Thursday. 

There have been no safety concerns tied to the affected vials, and vaccinations using Moderna’s other shots in Japan will progress as usual, Takeda said. An issue with one production line at Moderna’s contract manufacturing site in Spain may be responsible and an investigation is underway, a spokesperson for the Cambridge, Massachusetts-based company said. 

Japanese Prime Minister Yoshihide Suga told reporters Thursday that the suspension would not have a big impact on the country’s vaccination program. Vaccinations in Japan, which started late compared to other developed nations, has progressed quickly since early summer. About 43% of the population is fully vaccinated, including nearly 90% of its elderly over the age of 65. 

The situation is similar to a temporary halt in the use of BioNTech SE’s vaccine in Hong Kong and Macau earlier this year due to a packaging defect. It’s not as severe as pauses ordered by regulators, which happened with the Johnson & Johnson shot earlier this year in the U.S. to draw attention to a rare side effect. Still, there are concerns that even temporary stoppages can erode public confidence in the vaccines, which prevent serious coronavirus infections and deaths. 

Japan has a deal for 100 million doses of Moderna’s vaccine -- half to be delivered this year and half in 2022. Most of the shots are being used for the country’s workplace vaccination program through its largest companies and at mass vaccination centers run by the national government in major cities.
