Takeda Pharmaceutical Co Ltd (4502.T) of Japan said on Friday that metal contamination got into Moderna Inc (MRNA.O) COVID-19 vaccination dosages due to “human error,” prompting a recall.
In a recent study, Takeda and Moderna stated that a Spanish manufacturer identified contamination in certain vials in July, but supplies from the same batch were permitted to be transported to Japan.
After learning of the contamination, Japanese officials halted the use of three batches of Moderna shots comprising 1.63 million doses in August.
In collaboration with Takeda and the Spanish company Rovi, Moderna performed research (ROVI.MC).
The fault was caused by “incorrect assembly and was attributable to human error specific to visually misjudging the requisite 1mm space between the star-wheel and the stopper” of gear that fitted the caps on vaccine vials, according to the latest study.
Between June 27 and July 3, five successive batches of the Moderna COVID-19 vaccine produced at Rovi were studied.
The first three were sent to Japan but were later withdrawn due to the detection of stainless steel particles inside 39 vials.
