After results proving more than 95% efficacy in the nonuremic population [10,47], the use of this method is spreading, even if its high cost (about 150 US S per cycle); the possible lack of response in subjects with elevated levels of interleukin-2 receptor [45], or even the appearance of H B V mutants [5], lead to consider that it may be wiser to use the vaccine in the high-risk sectors of the population, where the results are nevertheless posi tive [11,12,34,39], The uremic patient, whether undergoing dialysis or not, is certainly subject to risk, and in this field, in fact, the use of the vaccine is steadily increasing.
