In Japan, foreign substances found in the Pfizer vaccine

Foreign substances, presumably crumb rubber from ampoule caps, were found in the Japanese prefecture of Okinawa in a Pfizer vaccine. This was announced on Tuesday at a press conference in Tokyo by the General Secretary of the Cabinet of Ministers Katsunobu Kato.

“On August 29, in the Okinawa Prefecture in the village of Yesho, foreign substances were found in an ampoule of Pfizer vaccine during vaccination. . Similar cases have been reported with the Moderna vaccine. It does not affect the safety of both drugs in any way, “he said.

Foreign substances were also found in two shipments of Moderna in Okinawa and Gunma prefectures. According to the results of the inspection, the Ministry of Health of Japan reported that it was rubber crumb from ampoule corks. Most likely, this happened as a result of mistakes by medical personnel. It is necessary to pierce the caps with a syringe, according to the recommendations of the department, at a right angle.

Last week, the Japanese authorities announced the suspension of the use of about 1.63 million doses of Moderna’s vaccine from three batches produced in Spain. The size of the unknown particles found in them reaches several millimeters. Kyodo reported that the unknown components could be metal particles as they react to magnets. At the time of the publication of the statement of the Ministry of Health, local authorities had already introduced about 170 thousand doses of vaccine from defective batches to the inhabitants of Japan.

On August 28, two deaths also became known among Japanese residents who received doses of the drug from batches in which foreign substances were found. The deceased are men 38 and 30 years old, who have not previously had chronic diseases and allergic reactions. They were vaccinated with the second dose of the vaccine on August 15 and 22, respectively. The day after vaccination, both had fever. Both died three days after vaccination for unknown reasons.

In Japan, vaccines are used by the British-Swedish company AstraZeneca, the American-German consortium of Pfizer and BioNTech companies, and the American company Moderna. At the moment, 69.2 million people (54.5% of the population) received the first dose of the vaccine in the country, and 55.2 (43.5%) received two doses.
