Neurological Autoimmune Disease attacks the brain

Multiple sclerosisis now thought to be a neurological autoimmune disease in which the immune system attacks the brain and spinal cord. It is most likely to occur in young people under the age of 40. But the vaccinations are often mentioning as a possible risk factor for Multiple sclerosisis. As the data from over 12,000 multiple sclerosis (MS) patients forming the basis of a study.

As the study investigating that the population’s vaccination behavior in relation to Multiple sclerosisis. It showed that five years before their diagnosis, Multiple sclerosisis patients were statistically less likely to receive vaccinations than comparator groups. Consequently, there was no positive correlation between vaccinations and the development of Multiple sclerosisis. The data covered over 200,000 individuals, including more than 12,000 multiple sclerosis patients.

Neurological autoimmune disease

The researchers finding that five years before being diagnosing, individuals who went on to develop MS had received fewer vaccinations than those who did not develop multiple sclerosis. This applied to all the vaccines investigated: those against pneumococci, meningococci, mumps, measles, rubella, chickenpox, human papilloma virus (HPV), hepatitis A and B, tick-borne encephalitis (TBE) and influenza.

The effect was particularly pronounced in the latter three cases: the control group had receiving significantly more vaccinations than the individuals who later developed multiple sclerosis. The causes are still a mystery. It may be that people perceive the disease long before they are diagnosed and therefore avoid putting additional stress on their immune system. Such effects are in fact evident in our data. Or perhaps the vaccines have a protective effect that prevents the immune system from attacking the nervous system.

Effect of chronic diseases

But in any case, given the large volume of data analyzed; we can conclusively state that there is no evidence; that recent vaccination increases the likelihood of multiple sclerosis or the onset of an initial multiple sclerosisepisode. The researchers also wanted to rule out the possibility; that the results might be an underlying effect of chronic diseases in general.

They therefore analyzing the data from two other groups; patients with Crohn’s disease, an inflammatory bowel disorder, and patients with psoriasis, a chronic skin disease. The vaccinations of these patients had also been recording five years before their diagnosis. Those patients, however, had received as many vaccinations as the healthy control group. Thus, the results are not due solely to the presence of a chronic inflammatory disease; but to behavior specific to multiple sclerosis.
