The demons can enter anyone who does not have the indwelling Holy Spirit or protection from the Most High as one of His Children. They need God's permission to possess any human. In this case, however, the vaccinated individual has given their "implied consent" to receive into themselves anything the beast system deems necessary (i.e. vaccine) and in so doing, they have opened the door for possession themselves! Just as the trap has been set by closing the portals on the demons, the enemy has set a trap as well for humans to act as the host for those trapped here. We are at WAR and most don't even realize it. A whole New War.
