More Moderna contamination fears in Japan

Japan's Kanagawa prefecture says it found another vial of Moderna's COVID-19 vaccine suspected of containing a foreign substance and has put the rest of the lot on hold.

Prefectural authorities on Tuesday said a pharmacist found several black particles in one vial upon checking for foreign substances before the vaccine's use.

Japan suspended the use of 1.63 million doses of Moderna shots last week after being notified of contamination in some of the supply.

Moderna and Spanish pharma company Rovi, which bottles Moderna vaccines, have said the cause could be a manufacturing issue, and European safety regulators have launched an investigation.

Moderna has said no safety or efficacy issues had been identified from the issue.

Kanagawa prefecture said the vaccine's domestic distributor, Takeda Pharmaceutical Co, had collected the vial with the suspected contaminant, and about 3790 people had already received shots from the same lot.

More Moderna shots were temporarily halted in two regions of Japan this week for what appears to be a separate issue of bits of the vials' rubber stopper breaking off when needles are incorrectly inserted.
