While damage from the spike protein seems certain, this statement at the end of one of the reports indicates that the vaccine, although introducing the S protein, actually provides some benefit. It would be nice to know if that was only for those who contract the disease because it seems to me that if you didn't contract it then it would be net harm because the benefit only accrues to those who become infected.

From the "SARS-CoV-2 Spike Protein Impairs Endothelial Function via Downregulation of ACE2" report:

"This conclusion suggests that vaccinationgenerated antibody and/or exogenous antibody against S protein not only protects the host from
SARS-CoV-2 infectivity but also inhibits S protein-imposed endothelial injury and ultimately
decrease cardiovascular complication-associated mortality in COVID-19 patients."

Keep up the good work. It is appreciated.
