Three articles in this issue of Clinical Cancer Research show how multiple vaccinations can lead to immunosuppression. Moreover, two studies in patients show that granulocyte macrophage colony-stimulating factor (GM-CSF) as an adjuvant immunostimulant to different kind of vaccines can lead to adverse outcome in terms of relapse-free and overall survival. Modulation of regulatory T-cell activity may be required to overcome this outcome and may be crucial for the successful development of therapeutic vaccines.
