[Immunoglobulins and antibodies of various classes in children immunized with live oral Shigella sonnei vaccine from the spontaneous mutant].
The authors determined the immunoglobulin and specific antibodies level in the blood serum of 17 children aged from 7 to 10 years during the immunization with live dysentery Some vaccine. Mancini's test demonstrated the absence of any differences in the amount of IgA and IgG in children of the given age group and in adults before the immunization; in comparison with adults, IgM was increased in children. 14 to 20 days after the immunization in children there was a significant elevation of the IgG only, whereas in adults the immunoglobulin level of all the 3 classes increased significantly. The titres of specific antibodies of the IgA-, IgG-classes and of hemagglutinins before the immunization detected by Coombs' test failed to differ in children from the titres of antibodies of these classes in adults; the level of IgM antibodies was much greater in children than in adults. The changes and accumulation of antibodies of various classes in children and adults during the enteral immunization with live dysentery vaccine differed significantly: in children the vaccine stimulated the IgA- and the IgM-antibody synthesis, whereas adults responded to the immunization by increased production of all the 3 antibody classes. On the basis of the noted immunological shifts a conclusions was drawn on a marked local immunization activity of the live enteral Sonne dysentery vaccine from the spontaneous mutant in children.
