title: [Antidiphtheria immunity in adult population of the Orenburg region].
abstract: The analysis of the level of antidiphtheria immunity in different age group of the adult population has shown that postvaccinal immunity resulting from immunization with adsorbed DT toxoid with reduced antigen content gradually decreases after the period of two years. The immune stratum remains sufficiently numerous only among persons aged 18-27 years (93.3%), persons over 38 years constitute a high risk group with respect to the possibility of diphtheria infection: the proportion of persons protected against this infection amounts to 71.3% in the age group of 38-47 years and 54.9% in the age group over 48 years, that is not sufficient.
