Begun as a crude version of homeopathy (“treat like with like”), in which a mild injected version of a disease would supposedly protect against the actual disease, vaccination soon developed into a military outpost, with the commander ordering the appearance of his scouts: antibodies. “Line up men, now hunt!”
Subconsciously and archetypally, the “modern science of vaccination” is doctrine. It is alchemy. It is magic. Going against the magic is tantamount to trying to overturn the very basis of life in the tribe.
