3 lots of Moderna Covid vaccine doses to be recalled by Janese distributor over stainless steel contamination

Biotech company Moderna has said its Janese distribution partner will recall three batches of its Covid-19 vaccines after a fourth batch of the company’s shots were found to be contaminated with stainless steel particles.

On Wednesday, the Janean Ministry of Health confirmed that the contaminants found in Moderna shots were stainless steel particles and were unlikely to pose any health risks.

Moderna’s domestic distributor in Jan, Takeda Pharmaceutical Co., reiterated the findings in a statement and noted “Stainless steel is routinely used in heart valves, joint replacements and metal sutures and styles. As such, it is not expected that injection of the particles identified in these batches in Jan would result in increased medical risk. ”

Despite the lack of health risk, Moderna said Takeda would recall three batches of the vaccine, which were suspended from use due to contamination. Last week, Jan stopped the distribution of approximately 1.63 million doses of the jab, as the media reported that the contamination was initially metallic.

On Tuesday, Jan reported new cases of contaminated Moderna shots. Kanagawa Prefecture said black particles were observed in vials, triggering the suspension of the entire batch. It was the fourth such incident in less than a week.

A study to find the source of the particles has been launched by European security authorities, Moderna and the Spanish bottling company Rovi. Takeda, quoting the probe, said the most likely explanation was related to friction between two pieces of metal in the instrument used to put corks in bottles. The instrument is made of stainless steel 316, it was confirmed.

Rovi has taken preventative measures, Takeda said in the statement. The use of the Moderna vaccine has now been suspended elsewhere in Jan despite other parties appearing to be free of the contamination. The suspensions have raised concerns that Jan’s already left vaccination campaign may suffer further.
