I think the vaxxed are perfectly possessed. They could be maybe lifted out of it, using their remaining days, if they wanted to, but one most scary effect they can't see/admit anything going wrong, even when their body literally falls apart.

"Fr. Martin insisted that no one can become possessed without some degree of consent: 'The effective cause of Possession is the voluntary collaboration of an individual, through his faculties of mind and will, with one or more of those bodiless, genderless creatures called demons.'"

"Of this frightening phenomenon, Malachi Martin writes: As the term applies, a victim of perfect possession is absolutely controlled by evil and gives no outward indication, no hint whatsoever, of the demonic residing within. He or she will not cringe, as others who are possessed will, at the sight of religious symbols as a crucifix or a Rosary."
