Could Spike Protein in Moderna, Pfizer Vaccines Cause Blood Clots, Brain Inflammation and Heart Attacks?

This is really important. The short story is: a bunch of research papers since December show that the spike protein alone causes a lot of the injury in covid. Were the vaccine developers aware of this when they developed vaccines based on the spike protein?

Cerebral venous sinus thrombosis (CVST) is only slightly lower for Pfizer/Moderna (4/million) than for Astrazeneca (5/million); for covid it is 39/million. (Taquet et al. Apr 2021)

The vaccines have “the potential to cause microvascular injury to the brain, heart, liver, and kidneys in a way that does not currently appear to be assessed in safety trials of these potential drugs.” This damage may be caused by the spike protein alone, which attaches to the blood vessel walls and is a neurotoxin.

Spike protein of SARS-CoV-2 crosses the blood–brain barrier in mice (Rhea et al. 16 Dec 2020)

Spike protein disrupts the blood brain barrier and causes inflammation of brain endothelial cells leading to neurological symptoms (Buzhdygan et al., Dec 2020) 

ACE2+ endothelial damage is a central part of SARS-CoV-2 pathology and may be induced by the spike protein alone. (Nuovo et al. Apr 2021)
