Japan: Two Men In 30's Die Days After Receiving Dose Of Moderna Vaccine From Batch Later Found To Be Contaminated

Two people, both in their 30's, died after receiving Moderna m-RNA COVID-19 vaccine shots from a batch whose use was later suspended after it was found that they may have been contaminated, Japan's health ministry said on Saturday.

Both men died this month within days of receiving their second Moderna doses, the ministry said in a release. Each had a shot from one of three manufacturing lots suspended on Thursday.

A causal link between the vaccine and the deaths has not yet been established, according to the ministry and Takeda Pharmaceutical Company, which distributes the Moderna vaccine in Japan.

"At this time, we do not have any evidence that these deaths are caused by the Moderna Covid-19 vaccine, and it is important to conduct a formal investigation to determine whether there is any connection," Moderna and its Japanese distributor Takeda said in a joint statement on Saturday.

The contaminants found in some vials in Japan are likely to be metallic particles, public broadcaster NHK reported, citing health ministry sources.

Japan suspended the use of about 1.63 million doses of the Moderna vaccine shipped to 863 vaccination centres nationwide on August 26 as a precautionary measure after foreign substances were found in some vials.
