Patient's choice: If a patient knows he is well-immune to Hep B, then he can get just the Hep A vaccine. If he does not know how high is Hep B immunity level is, but is at low risk of catching Hep B, he probably doesn't need a Hep B booster shot, and thus can get just the Hep A vaccine. If his Hep B immunity has decreased a lot, or he just wants to boost his Hep B immunity, he can get the Hep A+B vaccine.
