"Moderna vaccine, foreign matter is metal? How to see contamination in the manufacturing process
Foreign matter contamination of the new coronavirus vaccine made by US Moderna was reported, and the Ministry of Health, Labor and Welfare announced on the early morning of the 26th that some inoculations would be postponed. Foreign matter is said to be metal. There are no reports of safety concerns at this stage. Chief Cabinet Secretary Katsunobu Kato said at a press conference on the same day, "If you feel something is wrong, please consult your doctor."
Foreign substances that can be seen at a glance in the situation of prefectures are being investigated by Moderna. An executive of the Ministry of Health, Labor and Welfare said, "It is a substance that reacts with magnets and is a metal. It seems that it was introduced during the manufacturing process." "The risk of blood vessel blockage (because it's an intramuscular injection) is low, and the health risk isn't that great," said another executive.
Foreign substances were found to be mixed in 390 doses that were planned to be used at large-scale inoculation venues and occupational inoculation venues in 5 prefectures and 8 venues in Tokyo, Saitama, Aichi, Ibaraki, and Gifu. It is said that he did not notice in advance and inoculate. The inoculation is postponed for about 1.6 million doses made in the same manufacturing process. It is distributed to 863 venues nationwide. It is unknown how many people have been injected so far, but vaccination with foreign substances has not been confirmed.
Lots found to be contaminated were 3004667 (about 570,000 inoculations), possibly 3004734 (about 520,000 inoculations) and 3004956 (about 540,000 inoculations). The policy is to supply replacements for about 1.6 million times. The Ministry of Health, Labor and Welfare has said that it "wants to prevent" the impact on the delay in the vaccination plan, but an executive at the Prime Minister's Office said, "Since the vaccine is temporarily stopped at the venue, it will have an impact."
The contamination was noticed by medical staff at multiple venues after mid-August and reported to Takeda Pharmaceutical Company, which is in charge of imports and sales, and the Ministry of Health, Labor and Welfare reportedly grasped it on the 25th. All Moderna vaccines for Japan are manufactured at the same company's factory in Spain. Currently, it has undergone extensive maintenance and is now in a different manufacturing process."
