[134] This deliberate induction of the immune reaction is effective because it exploits the natural specificity from the immune system, and its inducibility.

CD8 + cytotoxic T cells are principally involved with the destruction of cells contaminated by international agents, for instance viruses or intracellular bacteria, and also the killing of some types of tumour cells. These cells are activated because of the interaction of their TCR with peptide bound to MHC class I molecules, which may be located on most cells.
The Th2 response is characterized by the discharge of cytokines (IL-four, five, and thirteen) which advertise the development of strong antibody responses to battle extracellular infections. These involve immunoglobulin E (IgE) antibody-generating B cells, along with the event and recruitment of mast cells and eosinophils that happen to be important for productive responses versus several parasites. Also, they greatly enhance the production of sure varieties of IgG that support in combatting bacterial an infection. As mentioned before, mast cells and eosinophils are instrumental in the initiation of acute inflammatory responses, like Individuals seen in allergy and asthma.
