Just to note, a bigger concern is not so much about the spike proteins themselves (made by genetically modified muscle cells) floating around, but more so about the LNPs which carry the genetic reprogramming payloads homing in on certain tissues and thus infecting certain cell types which are found here and there around the body.  These LNPs have been shown (by Pfizer to Japan before it was leaked) to have an affinity for both the spleen and the ovaries.

Now, for the last half decade or so I remember various scientism rag stories about 'new targeted drug delivery systems'.  News from that front went oddly quite for a year or so before the plandemic kicked off.  It's not the only thing which is big news to geeks then suddenly practically vanishes without a trace.  One of these days I'll look back and see if it were LNPs or related which were of such interest back then.
