Can the hepatitis B vaccine cause other medical conditions?

The Institute of Medicine's Immunization Safety Review Committee has examined the evidence regarding the hypothesis that the hepatitis B vaccine causes demyelinating disorders. Evidence of possible biological mechanisms that could produce this effect was weak. Additionally, the committee found that the epidemiological evidence favors rejection of a causal relationship between the hepatitis B vaccine in adults and multiple sclerosis (MS). However, the evidence was inadequate to accept or reject a causal relationship between the hepatitis B vaccine and all other demyelinating conditions. So, there may be a relationship between hepatitis B vaccines and demyelinating disease, but no relationship between the vaccine and MS.

You cannot get the hepatitis B virus from having the hepatitis B vaccine. The vaccine is normally given in a series of three to four shots or injections. This series of shots should protect you over the long-term from the hepatitis B virus, maybe even your entire life. All children should have the hepatitis B vaccine and should finish the series of shots by about 18 months of age. If you have any questions about the hepatitis B vaccine, talk with your doctor or healthcare provider.
