    • The present invention relates to a vaccine composition for breaking self-tolerance against a self-protein of a host, in particular for breaking self-tolerance against endogenous cytokines, in particular against the endogenous IL-4, IL-5, IL-13, IL-31 and IL-33 proteins in an animal host. The vaccine composition of the invention contains a polyprotein, a DNA encoding for the polyprotein and/or an RNA encoding for the polyprotein and one or more immunostimulatory oligonucleotides. The polyprotein comprises at least two self-protein segments of the host and one or more T-cell epitopes of non-host origin in between and/or adjacent to the at least two self-protein segments. The present invention further concerns the use of the vaccine composition for the prevention and/or treatment of diseases including the prevention and/or treatment of a pruritic condition and/or an allergic condition. In another aspect, the present invention provides a method for detecting the presence of autoantibodies against self-proteins that can be generated with the vaccine composition of the invention.
