Antibody persistence, 32 years after post-exposure prophylaxis with human diploid cell rabies vaccine (HDCV).
Summary of "Antibody persistence, 32 years after post-exposure prophylaxis with human diploid cell rabies vaccine (HDCV)."
In 1975-1976 forty-five persons severely bitten by rabid wolves and dogs in Iran were treated successfully against rabies with HDCV. In this study contact was made with 26 of 45 above persons, 32 years after their initial treatment and all had rabies neutralizing antibody ranging from 0.3 to 2.69IU/ml of serum. Of the 26 persons, 17 had received a booster dose of HDCV, 28 years ago and the remaining 9 persons, who had not received any booster since the initial treatment, were given one booster dose of HDCV. All 9 of these patients developed an anamnestic response after their booster inoculation. This study confirms the persistence of rabies neutralizing antibody in persons that received post-exposure vaccination with HDCV, 32 years previously. Furthermore, a single booster inoculation with HDCV resulted in anamnestic response in all individuals.

Medical and Biotech [MESH] Definitions
Post-exposure Prophylaxis
The prevention of infection or disease following exposure to a pathogen. This is most frequently addressed by administering a vaccine or anti-viral medication following exposure to a virus.
Vitelline Duct
The narrow tube connecting the YOLK SAC with the midgut of the EMBRYO; persistence of all or part of it in post-fetal life produces abnormalities, of which the commonest is MECKEL DIVERTICULUM.
Movement Disorders
Syndromes which feature DYSKINESIAS as a cardinal manifestation of the disease process. Included in this category are degenerative, hereditary, post-infectious, medication-induced, post-inflammatory, and post-traumatic conditions.
Antibody Diversity
The phenomenon of immense variability characteristic of ANTIBODIES. It enables the IMMUNE SYSTEM to react specifically against the essentially unlimited kinds of ANTIGENS it encounters. Antibody diversity is accounted for by three main theories: (1) the Germ Line Theory, which holds that each antibody-producing cell has genes coding for all possible antibody specificities, but expresses only the one stimulated by antigen; (2) the Somatic Mutation Theory, which holds that antibody-producing cells contain only a few genes, which produce antibody diversity by mutation; and (3) the Gene Rearrangement Theory, which holds that antibody diversity is generated by the rearrangement of IMMUNOGLOBULIN VARIABLE REGION gene segments during the differentiation of the ANTIBODY-PRODUCING CELLS.
Fluorescent Antibody Technique
Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
