Excellent article. There’s so much that we still don’t know, and the source of minute amounts of spike protein in plasma after vaccination is a critical piece of information. This is especially true as companies employ this technology in the prevention and treatment of other diseases.

Regarding the cell leakage hypothesis, I don’t Recall seeing how much spike protein is present in plasma of people infected with covid. It should seem to be a much higher level because of lysis of infected cells by T cells.
