My Wife And I (very Monogamous) Practice Oral Sex. My

My wife and I (very monogamous) practice oral sex. My wife has MS (she takes Tecfidera from Biogen) and I am considering the potential for contracting Hepatitis A and/or B to have complications that could stem from our sexual practices. I would like to know if inactivated (the type that is not contraindicated for users of Tecfidera, and suggested by her neurologist) vaccinations for Hep A and Hep B would be wise?
