Japan Suspends Another 1 Million Moderna Doses Over Contamination Concerns

Japanese authorities suspended another one million doses of Moderna’s COVID-19 vaccine on Aug. 29 at distribution centers in two regions over contamination concerns, according to the local governments.

The latest suspension came a day after officials reported that two men in their 30s died after receiving doses from other tainted Moderna lots placed under investigation—around 1.63 million doses—earlier this month.

Okinawa, a Japanese prefecture comprising more than 150 islands, announced in a statement it had suspended the use of Moderna COVID-19 vaccines at a major vaccination center in the city of Naha, The Japan Times reported.

“We are suspending the use of Moderna COVID-19 vaccines as foreign substances were spotted,” Okinawa officials said.

Also in Gunma prefecture, located north of Tokyo, contaminated lots were paused over similar concerns, though an official noted that they will continue distributing “lots that are not affected by the incident.”

More than 2.6 million Moderna doses are currently affected in Japan. Last week, three batches totaling 1.63 million doses got suspended over safety concerns after “foreign materials” were discovered in at least 390 doses—or 39 vials—of the Moderna vaccine coming from eight vaccination sites.

The Japanese Ministry of Health requested distribution centers not to use the suspended lots that were shipped to more than 800 centers nationwide.

A tiny black substance was found in a Moderna vaccine vial in Gunma, an official from the prefecture said, while in Okinawa, black substances were spotted in syringes and a vial, and pink material was found in a different syringe.

The country’s health ministry said some of the incidents may have been due to needles being incorrectly inserted into vials, breaking off bits of the rubber stopper.

Moderna previously described the contamination reports as a “particulate matter” that did not pose a safety or efficacy issue.

The U.S.-based drugmaker and Takeda Pharmaceutical said in an Aug. 28 joint statement that they have been notified of the deaths in Japan, calling it a “tragic event” and adding that there is currently no evidence that the jab caused these deaths.

“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,” the companies said.

The deaths of the two men, aged 30 and 38, occurred in August. They both suffered from a fever the day after getting a second dose from one of the suspended lots, and dying two days after that.

Nearly 1,000 people in Japan have died after receiving shots from Pfizer’s vaccine, while 11 are reported to have died after getting Moderna’s. The country’s health ministry said they haven’t established a causality link between the injections and the deaths.

As of Aug. 30, 15,969 Japanese citizens have died from COVID-19 since the start of the pandemic, according to health officials. A large part of the country has been placed under strict measures in response to the CCP (Chinese Communist Party) virus, which causes COVID-19.
