Preventing the infections

Hepatitis B (HBV) can be prevented with a vaccine. The vaccine is recommended for all babies, children and any adults who haven't received it yet. If a baby is born to someone with HBV, the vaccine and a shot of medicine called hepatitis B immune globulin can greatly lower the chance of infection. You also should take steps to stay away from contaminated blood and body fluids. For example, practice safe sex and don't share needles or razors.

Hepatitis C is different because there's no vaccine currently available. The best way to prevent hep C is to practice safe sex and not share needles or other equipment used to inject drugs.
