The contamination likely resulted from friction between two pieces of metal incorrectly installed in a production line, Moderna said.** Meanwhile on Tuesday in Kanagawa prefecture in Japan, a pharmacist spotted several **black particles** in a vial. The discovery came after 3,790 shots had been administered from the batch. Japan’s health ministry said that the contaminant was likely to be **rubber stopper material**, which also could have entered during the manufacturing process, according to Moderna's distribution partner in the country, Takeda.
