Ch 17 Vaccines

Ch 17 Immunizations and Immunoassays

TermDefinition
ACELLULAR Also known as a subunit vaccine.
ADJUVANTS Chemicals added to vaccines to improve the effectiveness of antigens.
AGGLUTINATION Involve the use of IgG or IgM to form large, interlocking aggregates (lattices) with particulate antigens.
ATTENUATED A live, but weakened, microbe.
COMPLEMENT FIXATION The process in which complement combines with an antigen-antibody complex.
CONJUGATED Vaccines made by combining a weak immunogen with a protein.
ENZYME LINKED IMMUNOSORBENT ASSAY ELISA.
FLUORESCENT ANTIBODY These techniques combine fluorescent dyes with antibodies to detect the presence of specific antibodies in the serum or the presence of microorganisms.
HEMAGGLUTINATION Agglutination reaction involving the clumping of red blood cells.
HERD IMMUNITY Protection against illness provided to a population when a pathogen cannot spread because the majority of the group are resisteant to the pathogen.
HYBRIDOMA Made by combining a myeloma and a B cell.
IMMUNIZATION Refers to the administration of any antigenic inoculum.
IMMUNODIFFUSION These tests are precipitation reactions carried out in an agar medium.
IMMUNOTOXIN A monoclonal antibody that has been combined with a toxin.
INACTIVATED Microbes that have been killed by heat or chemical methods.
MONOCLONAL ANTIBODY Product of a hybridoma.
NEUTRALIZATION An antigen-antibody reaction in which the harmful effects of a bacterial exotoxin or virus are blocked by antibodies.
PRECIPITATION REACTIONS Involve the use of IgG or IgM to form large, interlocking aggregates (lattices) with soluble antigens.
RECOMBINANT Subunit vaccines that are produced by genetic engineering.
SEROCONVERSION A change in a person's response to an antigen in a serological test.
SUBUNIT Vaccines that only use antigenic fragments of a microorganism.
TITER The concentration of serum antibody.
TOXOIDS Inactivated toxins.
VACCINATION Immunization.
VACCINE A suspension of organisms or fractions of organisms that is used to induce immunity.
VARIOLATION A crude method of vaccination using infected material from a patient.
WHOLE AGENT A vaccine that uses an intact organism.
