Vaccine study settles MS concerns

A large US study has found no greater long-term risk of multiple sclerosis or other acquired central nervous system demyelinating syndromes (CNS ADS) in those who have received vaccines.

The research settles concerns that the hepatitis B vaccine in particular may increase risk of MS because of the potential for molecular mimicry of the vaccine with myelin basic protein, a key immunodominant epitope in animal models of MS.
