[Diphtheria in the Maritime Territory].

The results of the analysis of the present epidemiological situation in diphtheria in the Maritime Territory are presented. The data on absolute and intensive characteristics, death rate due to this infection, the vaccination status of diphtheria patients, as well as the results of the study of the level and intensity of antidiphtheria immunity in the healthy population of the territory. The study revealed that the defects of collective antidiphtheria immunity correlated with morbidity rate among adults and children.

[The antidiphtheria and antitetanus immunities of children of the Maritime Territory after the use of adsorbed DTP vaccine and adsorbed DT-m anatoxin].

The state of collective immunity to diphtheria and tetanus in children of preschool age, depending on the kind of vaccine preparation used for immunization, was studied. The immunological potency of adsorbed DPT vaccine (i.e.

[Collective immunity to diphtheria in the children and adolescents of Vladivostok during a mass immunization against this infection].

The state of collective immunity to diphtheria in children and adolescents of Vladivostok was studied. Adsorbed DPT vaccine was shown to have higher immunological effectiveness in comparison with adsorbed DT toxoid with reduced antigen content. As revealed in this study, as early as in 2 years a part of the children lost their immunity, irrespective of the preparation used for vaccination, and enlarged the reserve of initially seronegative children and adolescents, capable of maintaining the epidemic process of diphtheria.
