Abstract: The invention pertains to an immunization scheme for inducing or amplifying an immune response involving Variant Surface Glycoproteins as carriers for antigenic structures against which the immune response is targeted. The invention is based on a specific priming and boosting schedule using the array presented and soluble VSG variants. Surprisingly, the immunization scheme of the invention elicits a strong and long-lasting antibody response in the immunized subject and therefore is applicable in vaccination approaches, immunotherapy and in the production of novel antibodies.

Abstract: The invention is based on a platform for vaccination and/or antibody generation. The invention is based on the display of small molecular immunogenic compounds on the coat of variant surface glycoproteins (VSG) on trypanosomes which results in a highly effective immune response when used as a vaccine or in immunization for antibody production. The herein disclosed antigenic particles are applicable for producing antibodies or can be directly used as vaccines for the treatment of various medical conditions. Most preferably the invention relates to the VSG based vaccines specific for dependency causing substances for the treatment of addiction or avoidance of adverse events during drug abuse. Other applications include methods and uses involving the disclosed compounds and compositions for a treatment or prevention of cancer, infectious disease, contagious neurodegenerative diseases, non-communicable disorders (e.g.
