title: [Persistence of protection induced by hepatitis B vaccine.].
abstract: Universal mass vaccination against hepatitis B virus in infants and adolescents, together with targeted prophylaxis for risk groups, is recommended since almost twenty years all over the world to prevent infection and related diseases. Safety and effectiveness of the vaccine have been clearly demonstrated while unambiguous data about long term protection and need of booster administration are not yet available, especially for high risk subjects like health care workers and dialysis patients. By means of new vaccines and new adjuvants better results could be obtained in a next future.
