Regarding foreign substances in Moderna's new corona virus vaccine found at the inoculation site in Kanagawa Prefecture, the Ministry of Health, Labor and Welfare has found that there is a high possibility of fragments of rubber stoppers that are rarely mixed in during the manufacturing process, and there is no safety problem. I announced it.
On August 31, Kanagawa Prefecture revealed that a black foreign substance was found in an unopened container of Moderna vaccine at the inoculation site in Yokohama City.
Takeda Pharmaceutical Company Limited, which handles domestic distribution, collected and investigated it, but according to the Ministry of Health, Labor and Welfare, it is highly possible that the rubber lid fragments of the container were mixed in when the lid was attached during the manufacturing process. I received a report on the 1st.
In Japan, there is a similar report at a rate of about 1 in 100,000, and even if it is used for inoculation, there is no risk of clogging of blood vessels due to intramuscular injection.
According to the Ministry of Health, Labor and Welfare, "In rare cases reported at home and abroad, there is no problem with safety and efficacy, and there is no need to refrain from vaccination."
On the other hand, it is expected that the results of the investigation will be announced soon for the vaccines with three lot numbers that are not used because it cannot be denied that foreign substances that appear to be made of metal may have been mixed in during the manufacturing process.
