Paulij – 30 December 2003 – The hepatitis B surface antigen (HBsAg) “a” domain harbors major B‐cell epitopes. Viruses with mutations in this region emerge after vaccination or during hepatitis B immune globulin (HBIg) prophylaxis. A strain with G145R replacement has been almost invariably isolated as a major escape mutant.
