Two Japanese men died days after getting the Moderna vaccine against COVID. Their doses came from a lot that was pulled from use. Three lots were pulled because contaminants were found in one of them, but the men who died got their doses from a different lot in which no contaminants were found, the Wall Street Journal reports. The other two lots were pulled because they were manufactured at the same time and at the same facility as the lot in which contamination was found.
Shots from those three lots were distributed by Takeda Pharmaceutical, Bloomberg reports. Takeda is calling for Moderna to investigate what the contaminants are and how they got there. The Japanese health ministry has said it’s not clear whether there’s any connection between the vaccination and the deaths. "There may only be a temporal relationship between vaccination and death," Fumie Sakamoto, an official at a Tokyo hospital, told Reuters. (Read more coronavirus vaccine stories.)
