Without diving down that bunny hole and/or revealing too much: Based upon what I can discern, the virus severely affects haemodynamics by directly inhibiting the normal cellular health of red blood cells, likely some effect of the spike protein, just as we've seen with the adverse effects of those who've gotten the 'shots. Blood clotting is merely a symptom, the true problem being the inability to provide oxygen to the organs: Without good laminar flow, the organs die of hypoxia. i.e. 'organ failure'.
In short, it's all about capillary blood flow or, in the case of literal COVID, lack thereof. Think about it: A possible bioweapon which literally targets the blood in a stealthy manner...a facet which took over a year to discern (or perhaps so-called 'scientists' were too biased to look).
I believe that a link between the virus and the diseased state of those with so-called 'comorbidities' (my preferred term is 'lifestyle disease') will be found to fully explain the causation as it pertains to red blood cells, but it's becoming patently clear that the negligent actions of the medical establishment - enacted by regulatory authorities - killed hundreds of thousands - if not millions - by inhibiting early, effective treatment (e.g. Ivermectin, etc.) to prevent the toxic effects upon diseased individuals, be they diagnosed with a comorbidity or otherwise 'asymptomatic'.
Furthermore, it's all but proven that limiting viral load with effective treatments overwhelmingly prevents the problems associated with the lungs in advanced stage COVID, the lungs merely being another pair of organs being inhibited proper blood flow.
The success of India in the past 2 months - TOTALLY ignored by the media, especially in the US - lends credence to my thoughts, their rate of 'vaccination' not corresponding AT ALL to the incredible drop in both 'cases' and daily deaths.
Furthermore, the observed adverse effects of the 'vaccines' demonstrate that it's less about the virus and the ACE2 receptors than it is about the spike protein itself.
Frankly, I do not believe it is coincidental that a signature clue has been found in the sequencing of the spike protein:
If 'science' actually pulls its head out of its backside and follows the clues the size of - as opposed to viral particles - A HOUSE, somebody please wake me up. Until then, I assure you that I won't be holding my breath...
