Official title:

Study type | Interventional |
Does vaccinating hemodialysis patients with Twinrix® (combination vaccine against hepatitis A and hepatitis B) result in a difference in hepatitis B antibody response in comparison to the monovalent hepatitis B vaccine? Hepatitis B infection is an important cause of mortality and morbidity. Current standard vaccination practices have low efficacy levels in patients (eg. hemodialysis patients) who are most susceptible of infection. Efficacy of the two regiments will be studied.
