Brief summary
The study vaccine has been developed for use in pre-dialysis/ haemodialysis patients and immuno-compromised individuals who could have or had a sub-optimal response following vaccination for hepatitis B with currently available commercial vaccines (target population). This study will aim to confirm in a clinical setting the consistency of production of three lots of the vaccine.
Detailed description
Double-blind, randomised, single centre study with three groups receiving three different lots of Henogen's adjuvanted hepatitis B vaccine according to 0, 1 months schedule. Blood samples will be taken at Month 0, Months 1 and 2.
