After primary immunization with adsorbed DPT vaccine antitetanus immunity was retained for 9-10 years in 90.6-98.4% of children covered by this study. The second booster immunization of children against tetanus with adsorbed DT toxoid with reduced antigen content, made at an interval prolonged to 7-10 years under the conditions of lower antitoxic immunity, ensured a high level of intense antitetanus immunity. These data point to the possibility of prolonging the interval between booster immunizations to 9-10 years and reducing the number of injections and antigenic load.
