Yeah, you know all that stuff the mutton crew are pushing about the proline stabilization of the vax spikes, which, in theory, means the spikes are unable to unfold, and expose the prion-genic epitopes...well..

SARS-CoV-2 S2P spike ages through distinct states with altered immunogenicity
"Here, we demonstrate that the prefusion-stabilized two-proline “S2P” spike—widely employed for laboratory work and clinical studies—unfolds when stored at 4C"


I mean that^ is also aside from the fact that the body does eventually break down those spikes and prion-genic epitopes are exposed at that point.
Enough to start a cascade? Quite possibly.
