Suspicious admixture has been detected in the Moderna vaccine flask in Japan.
According to Reuters, this time, the incident occurred in Kanagawa prefecture. A medical worker found some black particles in one of the flasks while checking the vaccine for extraneous materials before its use.
"Kanagawa prefecture said the vaccine's domestic distributor, Takeda Pharmaceutical Co Ltd (4502.T), had collected the vial with the suspected contaminant and that about 3,790 people had already received shots from the same lot. More Moderna shots were temporarily halted in two other regions this week. In some cases, foreign substances have been found in unused vials, whereas others appear to be caused when bits of the vials' rubber stopper break off when needles are incorrectly inserted. Takeda did not immediately respond to a request for comment on the Kanagawa incident. The company posted a notice on its website on Wednesday saying that on rare occasions during manufacturing, rubber stopper material can get mixed into the vaccine solution", writes Reuters.
Earlier, Moderna Inc's (MRNA.O) COVID-19 vaccine contamination woes in Japan widened with another million doses being temporarily suspended, after foreign substances were found in more batches and two people died following shots from affected lots.
