title: Hepatitis B surface antigen positivity after twinrix vaccination: a case report.
abstract: Travelers might have an increased risk of hepatitis B virus (HBV) infection. We report a case of prolonged transient hepatitis B surface antigenemia in a healthy Canadian female 8 days after administration of a combined hepatitis A and hepatitis B vaccine. Travel health providers providing hepatitis B vaccines need to be aware of this phenomenon and educate their patients accordingly.
