Does hepatitis B vaccine cause multiple sclerosis?
There is no evidence that hepatitis B vaccine causes multiple sclerosis (MS). Concerns about hepatitis B vaccination arose from France, after a few reports of a possible link between hepatitis B vaccine and MS. However, when the French data were examined closely, the rate of MS in vaccinated people was not significantly different from the expected population rate. With millions of vaccinations administered worldwide, it is likely that surveillance systems in some countries will receive some reports of MS, which seem to be related in time to vaccinations. As with all such reports, however, they only suggest the possibility of an association. Subsequent studies have found no increase in incidence of MS, or even relapse of MS, after hepatitis B vaccination.
