| Active Immunity | Immunity that occurs by an animal’s own immune response after exposure to foreign antigen. |
| Adjuvant | A substance given with an antigen to enhance the immune response to the antigen. |
| Anaphylaxis | A systemic, severe allergic reaction. |
| Antibody | An immunoglobulin molecule that combines with the specific antigen that induced its formation. |
| Antigen | Any substance that can induce a specific immune response, such as toxins, foreign proteins, bacteria, and viruses. |
| Avirulent | The inability of an infectious agent to produce pathologic effects. |
| Bacterin | A killed bacterial vaccine. |
| Core vaccines | Recommended vaccines for most animals to protect them from highly contagious diseases that are widespread in the environment. |
| Monovalent | A vaccine, antiserum, or antitoxin developed specifically for a single antigen or organism. |
| Noncore vaccines | Optional vaccines that are considered for animals at risk for developing disease based on geographic location and the lifestyle of the animal. |
| Passive immunity | Immunity that occurs by administration of antibody produced in another individual. |
| Polyvalent | A vaccine, antiserum, or antitoxin active against multiple antigens or organisms; mixed vaccine. |
| Preservative | A substance, such as an antibiotic, antiinfective, or fungistat, that is added to a product to destroy or inhibit multiplication of microorganisms. |
| Recombinant DNA technology | A process that removes a gene from one organism or pathogen and inserts it into the DNA of another. This also may be referred to as gene splicing. |
| Toxoid | Inactivated toxin that has been weakened by a chemical or heat treatment to eliminate the toxic qualities but retain antigenic properties. |
| Virulence | The ability of an infectious agent to produce pathologic effects. |
