Low dose intradermal versus high dose intramuscular hepatitis B vaccination in patients on chronic hemodialysis.

Patients with end-stage renal disease on hemodialysis (HD) are at high risk for hepatitis B infection. We randomly assigned 86 new patients on HD to receive either 40 microg intramuscular (group 1) or 20 microg intradermal (group 2) recombinant hepatitis B vaccine, in three doses at 0, 1, and 4 months. All patients were seronegative at baseline for hepatitis B surface antigen (HBs-Ag), hepatitis B surface antibody (HBs-Ab), and hepatitis B core antibody (HBc-Ab).
