"Although this version of primary IVC thrombosis is rare in Western countries..."
The fibrous structures pulled out of athletes and cadavers blood vessels are not what the article is referencing. In addition to it's rarity of IVC thrombosis outside of Nepal, the article you cited refers to a thrombus, an actual blood clot.
Again, these fibrous structures from the Jim Jones Jab are lacking key elements present in human blood, such as iron, potassium, magnesium, and zinc, which means they're formed by something other than blood.

Oh, boy, you cite the epic times as a source. Might as well cite the National Enquirer.
Mike Adams is the person who Epoch Times quotes as a source for your information. He is far from a credible source having been refuted numerous times.
