What are the myths about chiropractic and the immune system?
Understanding the Relationship Between Chiropractic Care and the Immune System
In recent years, a growing number of claims have circulated suggesting that chiropractic adjustments can significantly boost the immune system, cure infectious diseases, or even serve as a substitute for conventional medical treatments. While chiropractic care has legitimate and well-documented benefits for musculoskeletal conditions, separating fact from fiction is essential — particularly when it comes to immunity-related assertions. This article examines the most common chiropractic immune system myths, explores what the science actually says, and helps you make informed decisions about your health.
Myth #1: Chiropractic Adjustments Directly Boost the Immune System
One of the most widespread immunity chiropractic claims is that spinal manipulations can directly enhance immune function, making the body more resistant to viruses, bacteria, and other pathogens. Proponents often reference a study conducted during the 1918 influenza pandemic, suggesting that chiropractic patients had significantly lower death rates than those receiving conventional medical care.
While this historical anecdote is frequently cited, it lacks the scientific rigor necessary to draw any reliable conclusions. The data was collected informally, without control groups, randomization, or the methodological standards we expect from modern clinical research. Using a century-old, uncontrolled observation to justify sweeping claims about immune enhancement is scientifically irresponsible.
Current medical research does not support the idea that spinal manipulation has a direct, clinically significant effect on immune function. While some small studies have observed short-term changes in certain immune markers following chiropractic treatment, these findings have not been replicated consistently, and they do not translate into measurable health outcomes like reduced infection rates or faster recovery from illness.
Myth #2: Spinal Misalignments (Subluxations) Suppress Immunity
A foundational concept in traditional chiropractic philosophy is the notion of “vertebral subluxation” — the idea that misalignments in the spine interfere with the nervous system and, by extension, with every bodily function, including immunity. According to this spine immunity myth, correcting these subluxations restores the body’s natural healing ability and strengthens immune defenses.
The problem with this claim is that the concept of vertebral subluxation, as defined in chiropractic tradition, is not recognized as a valid clinical entity by mainstream medicine or by major scientific and medical organizations. While spinal dysfunction is a real and treatable condition, the broader idea that subluxations silently suppress immunity without causing obvious symptoms is not supported by credible anatomical or physiological evidence.
The nervous system and immune system do communicate in complex ways — a field known as psychoneuroimmunology — but this relationship is far more nuanced than the simplistic model that chiropractic adjustments can “unlock” immune potential by correcting spinal alignment. Claims that go beyond managing pain and mobility into the territory of immune regulation require a much higher standard of evidence than currently exists.
Myth #3: Chiropractic Care Can Prevent or Treat Infectious Diseases
Perhaps the most dangerous of all immunity chiropractic claims is the suggestion that chiropractic treatment can prevent or treat infectious diseases such as the flu, COVID-19, or even cancer. During the COVID-19 pandemic, several chiropractic practitioners faced scrutiny and regulatory action for suggesting that their treatments could serve as a preventive measure against the virus.
There is no credible clinical evidence that chiropractic adjustments can prevent viral or bacterial infections, accelerate recovery from infectious illness, or replace vaccines, antibiotics, or other evidence-based treatments. Making such claims is not only misleading — it can be genuinely harmful if patients forgo proven medical interventions in favor of spinal manipulation.
Reputable chiropractic organizations, including the American Chiropractic Association (ACA), have themselves cautioned against overstating the immune-related benefits of chiropractic care and have encouraged practitioners to adhere to evidence-based standards when communicating with patients.
Myth #4: All Chiropractors Believe These Claims
It is important to acknowledge that not all chiropractors subscribe to these expansive, unverified claims about immunity. The chiropractic profession is not monolithic. A significant and growing segment of practitioners operates from an evidence-based framework, focusing their practice on what has been scientifically validated — primarily the management of musculoskeletal pain, particularly low back pain, neck pain, and certain types of headaches.
Evidence-based chiropractors are often critical of colleagues who make exaggerated health claims, recognizing that such assertions damage the credibility of the profession as a whole. When seeking chiropractic care, patients are encouraged to look for practitioners who communicate transparently about what their treatments can and cannot do, and who do not discourage conventional medical care.
What Chiropractic Care Can Legitimately Offer
To be clear, dismissing the chiropractic immune boost truth does not mean dismissing chiropractic care entirely. There are well-supported benefits to chiropractic treatment that are worth acknowledging:
- Management of low back pain: Multiple systematic reviews and clinical guidelines recognize spinal manipulation as a potentially effective treatment for acute and chronic low back pain.
- Neck pain relief: Chiropractic manipulation and mobilization have been shown to provide meaningful relief for certain types of neck pain.
- Tension-type headaches: Some research supports chiropractic care as a helpful intervention for tension headaches and cervicogenic headaches.
- Improved physical function: By reducing pain and improving joint mobility, chiropractic care may help patients engage more fully in physical activity, which in turn supports overall health — including, indirectly, immune resilience.
These are meaningful contributions to patient health. However, they are very different from claims that chiropractic directly modulates immune function or treats systemic disease.
