The claim
日本赤十字社が「レプリコンワクチン接種後の献血をお控えいただく場合がある」と広報？
Original review summary
The review says the claim is misleading: the Japanese Red Cross applies post-vaccination blood-donation deferrals, as it does for other vaccines, rather than treating replicon vaccination as a unique reason to avoid donating. It reports that people can donate 48 hours after receiving a replicon vaccine.[S1]
Additional context
The review reports that the 48-hour deferral for replicon vaccines was based on assessments of side-effect timing and evidence about how vaccine mRNA declines after injection. [S1]
