COVID AND THE VACCINE - TRUTH, LIES, AND MISCONCEPTIONS REVEALED, page-39026

Article you linked doesn't mention it was covid or if the clot happened after or before the Vax.

Best reference we have is by looking at how many people had heart/clot problems pre the jab in 2020 when the ferocious Alpha variant was out and about, I don't have the data at hand but I cannot recall any and the amount of problems of heart/clotting issues over the last six months is significant.

I'm not discounting Covid as the cause, we know it can cause mico clotting, but my money is more on the vax where the clotting seems more aggressive, it's all about spike protien and the vax's spike's are Free Range.
