Japan Suspends Use of Moderna COVID-19 Vaccination After Contaminations

An estimated 1.6 million Moderna vaccines were pulled from use in Japan


Japan has stopped the use of roughly 1.63 million doses of the Moderna vaccine after contamination was found in unused vials on Thursday.

The contaminations were reported in multiple locations and it is possible some were administered. No adverse effects have been reported. At least 800 doses were affected.

“Takeda Pharmaceutical Co., a Japanese drugmaker in charge of sales and distribution of the vaccine in Japan, said it decided to suspend use of doses manufactured in the same production line as a safety precaution,” reports AP News. “It asked Moderna to conduct an emergency investigation and told medical institutions and organizers to stop using the vaccine produced in Spain and shared the production numbers that may be affected.”

Japan’s inoculation campaign was previously delayed because the nation’s regulatory approval of COVID-19 vaccines was slower than other industrialized countries. Additionally, some experts say the nation’s vaccination roll-out has been “insufficient for achieving mass vaccination … less than 15% of imported doses have been used so far.“ Furthermore, “only nurses and medical doctors can legally vaccinate citizens,” causing hiring shortages. 

According to a review published by the National Center for Biotechnology Information, the “slow roll-out could cause an emergence of new mutants.”

The Japanese government had previously wanted to complete the vaccination of 36 million citizens ages 65 and older by the end of July 2021.

With the halt on the use of Moderna vaccines, there is concern that their efforts will be detrimentally stalled.

Mass vaccination centers in Japan, including universities and large companies, were sent the Moderna vaccination. 

Chief Cabinet Secretary Katsunobu Kato told reporters, “We will do utmost in order to avoid any impact on vaccination progress, especially at worksites and large-scale centers.”

Prime Minister Yoshihide Suga promised reporters he would make safety this government’s top priority. He said the contaminations “would not have a significant impact” on the continued efforts to vaccinate Japanese citizens.

Suga has been plagued by criticism regarding his handling of the pandemic. 

All COVID-19 vaccines used in Japan are currently from foreign manufacturers.

“While Japan has also approved both the Pfizer and AstraZeneca vaccines, concerns over blood clot issues delayed rollout of the latter until this week; it is being restricted to those 40 and over, as in Britain,” per CBS News.

The Prime Minister’s Office said Wednesday that over 42% of Japan’s general population was fully vaccinated.

    I live in Vancouver Washington. Today my wife, 2 year old and I went to Buffalo Wild Wings and due to mask mandates being implemented again they had a sign like most businesses do saying “No Mask No Entry” we have yet to comply since the reimplementation because of we refuse to comply to unconstitutional policy that claims benefit with no science or data to support the mask claim. We chose to go into the restaurant like we have done at other locations and this was the first time we actually were refused service. The gal asked us if we had masks and we said “no it’s against our religion to cover our face.” She responds after a pause.. “but it’s a mandate.” I respond. “There is no proof in efficacy that masks prevent or slow the spread and it’s against our religion.” She says and I’m paraphrasing “I can’t let you come in.” I say “This is medical apartheid, I guess segregation is real.” Then we kindly walked out and went to a Mexican restaurant down the street. Door sign said the same thing, yet they let us in and served us dinner. To me this means, stand up for your rights as a human and don’t give the people your business if they conform to these mandates. Drive down the street and try multiple places if that’s what it takes. Not all people are confirming and we need to support those people and encourage them to not be afraid to feel ostracized and uncomfortable. The more this happens the more we can get back to normal.
