At the turn of the century, a gene called VMAT2 was discovered. This gene eventually became known as the God Gene. The God Gene predisposes people to have spiritual experiences. Department of Defense scientists used this information to create a vaccine against religious fundamentalism. It was a viral vaccine that spreads via air and is designed to inhibit the expression of the VMAT2 gene causing people to become less religious.

-Rudolf Steiner: Fall of the Spirits of Darkness Lecture 13

"A longing will arise (and become) general opinion: Whatever is spiritual, whatever is of the spirit, is nonsense, is madness! endeavors to achieve this will be made by bringing out remedies to be administered by inoculation just as inoculations have been developed as a protection against diseases, only these inoculations will influence the human body in a way that will make it refuse to give a home to the spiritual inclinations of the soul. People will be inoculated against the inclination to entertain spiritual ideas. Endeavors in this direction will be made; inoculations will be tested that already in childhood will make people lose any urge for spiritual life."

[page 199, 200] Steiner:
"I have told you that the spirits of darkness are going to inspire their human hosts, in whom they will be dwelling, to find a vaccine that will drive all inclination towards spirituality out of people's souls when they are very young, and this will happen in a roundabout way through the living body. Today, bodies are vaccinate against one thing and another; in future, children will be vaccinated with a substance which it will certainly be possible to produce, and this will make them immune, so that they do not develop foolish inclinations connected with spiritual life 'foolish' here, of course, in the eyes of materialists.
