The authors present the results of studying the immunological efficacy of a dry alcoholic typhoid vaccine enriched with S. typhi Vi-antigen in the assessment of this vaccine in controlled epidemiological trial during the immunization of children aged 7--8 years. O- and Vi-antibodies were tested in the reaction of hemagglutination, H-antibodies--in the agglutination reaction with the microbial diagnostic agent, the properties of antibodies--in a test with cystein, and bactericidal properties of the sera--against the virulent S. typhi strain. Examination of 355 coupled sera obtained before and 3 weeks after the immunization demonstrated a high level of Vi-(1:47) and of the O-(1:580) antibodies and high bactericidal properties of the sera in persons vaccinated with the alcoholic vaccine enriched with the S. typhi Vi-antigen. The results obtained and the data on the formation of prolonged immunity following a simgle immunization suggested that a high protective effect was caused by a combined action of the O- and Vi-antigens contained in the vaccine in optimal doses. |
