The Pfizer/BioNTech vaccine (BNT162b2) is composed of an mRNA that produces a membrane-anchored full-length spike protein. The mouse studies suggest that an untruncated form of the S1 protein like this may cause a microvasculopathy in tissues that express much ACE2 receptor. A truncated form of S1 was much less damaging in mice.

 

While there are pieces to this puzzle that have yet to be worked out, it appears that the viral spike protein that is the target of the major SARS-CoV-2 vaccines is also one of the key agents causing the damage to distant organs that may include the brain, heart, lung, and kidney. Before any of these vaccines are approved for widespread use in humans, it is important to assess in vaccinated subjects the effects of vaccination on the heart [...].

 

Vaccinated patients could also be tested for distant tissue damage in deltoid area skin biopsies [...]. As important as it is to quickly arrest the spread of the virus by immunizing the population, it would be vastly worse if hundreds of millions of people were to suffer long-lasting or even permanent damage to their brain or heart microvasculature as a result of failing to appreciate in the short-term an unintended effect of full-length spike protein-based vaccines on these other organs.
