Abstract
The authors describe the case of a 70-day-old boy who was mistakenly diagnosed as suffering from acute hepatitis B, when he presented with persistent unconjugated hyperbilirubinemia and transaminasemia and was found to be seropositive for the hepatitis B surface antigen. The antigenemia was transient and related to his recent immunization with Infanrix-Hexa. Caution is required during interpretation of a positive HBsAg test that is obtained within 28 days after vaccination against hepatitis B.
