From the
Catechism of the Catholic Church:
675 Before Christ's second coming the Church must pass through a final trial that will shake the faith of many believers. The persecution that accompanies her pilgrimage on earth will unveil the "mystery of iniquity" in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. the supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh.
676 The Antichrist's deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatological judgement. the Church has rejected even modified forms of this falsification of the kingdom to come under the name of millenarianism, especially the "intrinsically perverse" political form of a secular messianism.
677 The Church will enter the glory of the kingdom only through this final Passover, when she will follow her Lord in his death and Resurrection. The kingdom will be fulfilled, then, not by a historic triumph of the Church through a progressive ascendancy, but only by God's victory over the final unleashing of evil, which will cause his Bride to come down from heaven. God's triumph over the revolt of evil will take the form of the Last Judgement after the final cosmic upheaval of this passing world.
--------------Believing that "the Vaccine" will save us rather than Jesus Christ is pre-figured in the story of the "Golden Calf." The Israelites put aside the worship of the True God who had saved them from Pharaoh to worship a man-made invention, the "Golden calf."
The word "vaccine" comes from the Latin word "vacca," meaning cow. This invention was named after a cow because the first "vaccine" was made of the "Cowpox" virus as a way to prevent "Smallpox."
Hence, by worshiping "the Vaccine," we are worshiping a "god" in "likeness of a cow."
Those who are faithful to Jesus and Mary know that only God can save us. We cannot save ourselves through our own inventions. There is only one solution, short of a supernatural intervention, for the Catholic who cannot see this: he must examine his conscience and confess his sins to a Catholic priest. Until this happens, he will be deceived no matter what you tell him.
