"The Palmers espoused anti-vaccination opinions in the early part of the 20th century, rejecting the germ theory of disease in favor of a worldview that a subluxation-free spine, achieved by spinal adjustments, would result in an unfettered innate intelligence; this, along with other healthful lifestyle choices, would allow a person to thwart disease by marshaling the body's natural recuperative abilities...because a significant portion of the chiropractic profession has aligned itself against one of the most successful health care initiatives of the past 100 years, the issue of chiropractic and vaccination will continue to be a source of contention, scrutiny and perhaps even animosity between chiropractic and medicine."
