The claim
コロナワクチン、金属片入っていたけどスルー
Original review summary
The review says the claim that metal fragments in COVID-19 vaccines were ignored is false: affected vaccine lots were recalled, not overlooked. It reports that three lots totaling 1.62 million doses were withdrawn after contamination was found.[S1]
Additional context
In mid-August 2021, foreign material was found in unused vaccine containers at eight locations; the affected lots were recalled and the manufacturing cause was investigated. [S1]
