People who have received a haematopoietic stem cell transplant are recommended to be revaccinated after transplantation. This is because of the loss of immune memory that often follows the transplant procedure.
A 3-dose schedule at 6, 8 and 12 months after transplant is required using:
a single dose of H-B-Vax II dialysis formulation (40 µg) at each schedule point, or
Engerix-B adult formulation (20 µg) in each arm at each schedule point (that is, a double dose on each occasion), or
the standard vaccination course, with checking of serology 4–8 weeks after the last vaccine dose
