Karl, The first paper tells us that the vaccines may help prevent the spike protein from the virus from causing damage. It doesn't seem to say the vaccine will cause a problem.

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.
