The stabilization effect of the triplex vaccine

Cancer immunoprevention vaccines are based, like all vaccines, on drugs which gives to the immune system the necessary information to recognize tumor cells as harmful. The vaccine, in endogeneous tumors, cannot eliminate all tumor cells, but maintains them to a non dangerous level. In this paper we show that the vaccine's administrations acts as a stabilizing perturbation for the immune system. Results suggest that it is possible to model such an effect using ODE based technique with an "external input".
