I had some doubt as to wether getting vaccinated for Hep A & B would effect my Hep C status. My Gastro assured me it would not and recommended I get vaccinated for both. I did that in 2005 with no side effects or weirdness. The Hep A vaccine is one shot, the Hep B vaccine is three shots over a six month period.
From what I understand, both A & B can be contracted for example: If you go to a buffet and eat infected food (mice feces, etc.), go on a cruise and buy food from street vendors, restaurants in foreign lands, and so on...
Ask your doctor if these vaccines are right for you....
