I think it is "spike protein" itself. Everything from failed virus to not-a-vaccines was developed to deliver that "spike protein" into human bodies.
Even if you look at simple fact, that natural human immunity to regular coronaviruses is based on capsid and spike mount proteins and not on the spike proteins of coronaviruses (and other viruses with spikes, like adenoviruses or flu too), you will easily figure out that all that vaxx shit have absolutely nothing to do with providing immunity to failed (or planned, but non-existent) virus.
