Active and Passive Immunization
Immunity to infectious microbes can be
achieved by two ways:
1.Active immunization: Immunity

Characteristics of Adaptive
Immune response is highly specific for the antigen
that triggered it.
Receptors on surface of immune cells have same
specificity as the antibody/effector activity that will be
Exposure to antigen creates an i
An adaptive immune response mediated by specific
cells of the immune system.
Primary Function Of Cell Mediated Response
Eliminate Intracellular Pathogens
Eliminate Tumor Cells
Both Ag Specific And Non-specific cells Are Involve
