A "good" chance? From the rest of your post I'd rather think it's a low chance. Very low. The nanolipids, and I'm now going mostly by what I remember from the debate around the biodistribution study, seem to get stuck in the tissues of internal organs, for the most part. At the time, nobody could know exactly what they are up to in there, but I remember distinctly that Vanessa Schmidt-Krüger mentioned that if you think "nanoparticles" and "ionized" in the same sentence, you next association should be "cancer".
Apparently, it took those particles a couple of weeks to get stuck there, so maybe right after the injection they could get expelled from the body and get into somebody else's body, but otherwise it seems as if they just stay in the injectees organs.
The other reason I don't believe in shedding is a spiritual one. The injection was a very clear cut matter of decision. Making the decision against it required significant sacrifice on a personal level, but seemed very much doable for pretty much everyone. Orthodox don't believe in prosperity gospel or anything like that, but there is a connection between your decisions and what happens to you. If trying to maintain contact to the jabbed people around us or loved ones, or trying to convince others of the truth, would get you the same punishment as them, then that would indeed have very weird implications, from a religious perspective.
Orthodox don't even believe in multiple spoons. Like, specifically, they canonically don't believe in that. The jab is a similar situation, but in reverse. If fundamental decisions like our refusal ultimately didn't matter, then literally nothing would matter, in terms of significance.
I know, some people might argue "God works in mysterious ways" and I shouldn't project my limited understanding of justice onto God, but on the other hand, justice isn't removed from what we perceive noetically. I've been skeptical of the concept of shedding very much from the beginning, because it seemed like a way to infuse the Christians with the same panic that the NPCs felt.
