I want to investigate the relationship between Hepatitis B vaccination and incidence rate of multiple sclerosis(MS) Would anyone introduce me some. numerous scientific studies and expert panel reviews do not suggest a link between the hepatitis B vaccine and multiple sclerosis. This fact sheet answers the. You need vaccines to protect you from severe and sometimes fatal that some vaccines, like those that prevent hepatitis B, caused MS.

The following year, HB vaccine was added to the national immunization program for all young babies and preteenagers. This intensive campaign had quickly exceeded its expected targets by also encouraging the adult population to be mass-vaccinated, whereas the vaccination of the infants remained less significant.

MS cases in some vaccinated adults were rapidly notified to the French national pharmacovigilance system ANSMtriggering investigation by this agency. This inquiry, started inwas therefore already underway when French media revealed possible occurrence of post-immunization MS in This year, French health authorities abruptly terminated routine school-based vaccination of preteens, and adult HB vaccination began to be less widespread.

Several epidemiological studies have been evaluating the correlation between HB vaccination and MS in adults for a decade. Most of these publications found the absence of a link [ 2 — 6 ] or a slightly increased risk, but not sufficiently significant on the statistical level [ 7 — 9 ].

However, different opinions have also been formulated. Costagliola on request of the French pharmacovigilance.

Another case—control epidemiological study was conducted to evaluate serious post-vaccination adverse events registered in the United States through a spontaneous reporting system in the VAERS database. Materials and methods Databases We compared data from two independent national databases: ANSM This organization identifies spontaneous adverse event reports emerged in the aftermath of vaccinations since the beginning of the establishment of HB immunization The most common diseases reported were neurological damages of myelin, known under the generic term of demyelinating diseases.

This condition is clinically called MS when at least two attacks of demyelination repeat themselves. When the neurological disorder remains single, without temporal or spatial diffusion, we speak of central nervous system demyelination.

The researchers concluded that hepatitis B vaccination was not associated with demyelinating disease in the study population.

Other studies conducted in the US Ascherio and colleagues,in Europe Confavreaux, and in British Columbia Sadovnick and Scheifele, also evaluated the possible link between hepatitis B vaccination and MS, and also found no association between hepatitis B vaccination and MS.

Inthe Institute of Medicine IOM reviewed published and unpublished research to determine if there was a link between hepatitis B vaccine and demyelinating neurological disorders, including MS in adults. The committee found that the epidemiological evidence does not support a causal relationship between hepatitis B vaccine in adults and multiple sclerosis. What research has been conducted on vaccines and other autoimmune diseases?

CDC takes concerns about vaccines and immune system diseases and disorders very seriously. Researchers at CDC and elsewhere have conducted studies to examine the possible link between vaccines and autoimmune conditions like MS, diabetes, and asthma.

These studies have been reassuring, providing no evidence to suggest a link between vaccines and autoimmune conditions. As part of ongoing vaccine safety surveillance, CDC continues to conduct research to examine the effects vaccines may have on the immune system.
