Inside your veins your blood is blue. When it oxidizes with oxygen it turns red. When it comes out in large volume, it looks very dark, almost black like.
It's not blue in your veins. If it were blue in your veins, drawing blood directly from your veins into a vial would bring out blue blood. It only looks bluish due to the light filtering through your skin.
You can color me skeptical on this one. I’m gonna go on record and say that I don’t think the vaccine turns your blood black lol
