Question | Answer |

Effector response | Action that occurs after recognition and binding of antigen by antibody; lysis by complement proteins is an effector response |
Memory response | The attribute of the immune system mediated by memory cells whereby a second encounter with an antigen induces a heightened state of immunity. |
Innate immunity | Nonspecific host defenses that exist prior to exposure to an antigen and involve anatomic, physiologic, endocytic and phagocytic, and inflammatory mechanisms |
Adaptive immunity | Host defenses that are mediated by B and T cells following exposure to antigen and that exhibit specificity, diversity, memory, and self-nonself recognition. |
Vaccine | A preparation of immunogenic material used to induce immunity against pathogenic organisms |
Attenuate | To decrease virulence of a pathogen and render it incapable of causing disease. Many vaccines are attenuated bacteria or viruses that raise protective immunity without causing harmful infection. |
Serum | Fluid protion of the blood, which is free of cells and clotting factors |
