Thank you for mentioning this newer study. However, this study only showed that spike proteins (not vaccine-induced spike protein) harm the endothelial cells. Thus, the arguments presented in the article still stand - that studies like this one do not prove that vaccine-induced spike proteins harm blood vessels.

Even the authors of the said study wrote that:

"This conclusion suggests that vaccination-generated 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."

I hope that's clear but let me know if it's not or if I'm misinterpreting something.
