[Reactogenicity and immunologic activity of live enteric Sonne dysentery vaccine from a spontaneous mutant].
Live dysentery Sonne vaccine from a spontaneous mutant proved to be practically areactogenic and specifically harmless in oral immunization of children aged from 7 to 13 years, in doses of from 3 to 25 milliard live microbial cells and in single and triple immunization schemes. Weak reactions of the gastro-intestinal tract were noted with the same frequency (1.7%) in children immunized with the vaccine and in children given placebo (2.2%). There proved to be a significant increase in the serum of the immunized persons of the level of specific hemagglutinins, and also of the IgA-and IgM-titers in 82% of the persons vaccinated; they persisted at a high level for 2 months. The appearance of IgA-antibodies in high titres in the persons vaccinated orally pointed to a marked local and general immunological activity of the live dysentery Sonne vaccine from the spontaneous mutant processing the capacity to survive in the intestine of children for a long time.
