It is only natural for researchers to try to find a cure and cause for MS, since currently, even if the process of the disease is well known, the scientific community has lots of missing answers when it comes to its causes and cure.

After a few anecdotal reports of MS following HepB administration and two cases controlled studies that showed an increase in the incidence of MS in vaccinated persons ( even if the results were not statistically significant), the hypothesis that vaccines might cause MS is plausible. However, according to two large case-control studies that evaluated whether HepB causes MS or whether tetanus, influenza, and HepB vaccines exacerbate MS’s symptoms, showed that there is no association between the those vaccines and MS.

There were other well-controlled studies that found that the influenza vaccine did not exacerbate MS’s symptoms. According to a retrospective study of 180 with relapsing MS, the influenza vaccine is more likely to prevent exacerbations of MS. In a prospective, multicenter, randomized double-blind trial of influenza vaccine among 104 patients with MS, the exacerbation of symptoms or change in disease course was not associated with the immunization process.

The scientific community is always skeptical when it comes to irrelevant facts. However, the studies proved that people with MS shouldn’t blame HepB or influenza immunization, and also, the studies proved that these vaccines are safe and are not likely to cause MS.
