Japan to Dispose 1.63M Moderna Doses Due to Contamination

Japan has disposed of 1.63 million doses of Moderna vaccine as there was contamination found in the unused vials. 

The disposal of doses has raised concerns over the shortage of supply of the vaccines amid the rising COVID-19 cases in the country.

According to the health ministry, multiple vaccination sites were contaminated. Officials say some doses may have been given, but no adverse health effects have been reported so far.

As a precaution, Takeda Pharmaceutical Co., the Japanese drugmaker in charge of the vaccine’s sales and distribution in Japan, has decided to stop using doses made on the same production line. 

It asked Moderna to conduct an emergency investigation and advised medical institutions and organizers to stop using the vaccine made in Spain and share the possible production numbers.

Earlier, Moderna said that there has been “particulate matter” in the vaccine.

“Moderna confirms having been notified of cases of particulate matter being seen in drug product vials of its COVID-19 vaccine,” Moderna said.

“The company is investigating the reports and remains committed to working expeditiously with its partner, Takeda, and regulators to address this,” it added, referring to Japan’s Takeda Pharmaceutical.
