The present invention relates to a pharmaceutical combination of compositions for use in the treatment or prevention of a disease having cells bearing a target antigen as a vaccine and to a method for vaccination of a mammal, especially of a human for raising a cellular immune response directed against cells of the mammalian recipient, especially human recipient, which cells express a target antigen. The target antigen can e.g. be an autoantigen like a malignant antigen, i.e. a tumour-specific antigen. The pharmaceutical combination of compositions comprises a first composition and a second composition, wherein the second composition is for administration to recipient subsequent to the administration of the first composition, e.g. 2 to 10 days after the first composition. The pharmaceutical combination of compositions has the advantage of raising an effective antigen-specific T-cell response against cells bearing a target antigen that can be a malignant autoantigen, e.g. for raising an antigen-specific T-cell response against cells bearing a tumour-antigen. A further advantage is that the pharmaceutical combination of compositions can raise an antigen-specific T-cell response within a comparatively short time.
