Haemodialysis patients are susceptible for infections due to a continuous mildly activated immune system. About 40% of the haemodialysis patients does not respond to the standard HBV vaccination procedure by achieving an adequate level of protection (anti-HBs titer>100 IU/L), also named non-responders. Recently, a pilot study demonstrated an additive effect of Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) to eventually reaching an adequate protection level. MedDRA version: 8.1 Level
