The IL10/IFNγ ratio is derived and compared to a threshold. If the IL10/IFNγ ratio of less than 4 shows that the patient is expected to develop the preventive or therapeutic response to the immunogenic composition. The group of inventions also refers to using IL10 and INFγ as biomarkers and a kit for analysing the above method.
