Thank you for mentioning my article. Although I'm no expert, I think there's likely no cause for concern. The mRNA-induced protein expression typically last for a few days only (~48 hours). So, I think the spike protein production will be mostly gone within a week, making the long-term vascular problems unlikely.

For more context, I think you can see this article: https://medium.com/microbial-instincts/hypothetical-lasting-health-problems-of-mrna-vaccine-vs-coronavirus-ee11bddb9637
