[Use of ADT-toxoid with decreased antigen content for the immunization against diphtheria and tetanus of children with contraindications to the inoculation of APDT vaccine. I. Revaccination of children with allergic reactivity].

A single inculation of ADP-toxoid with diminished antigen content (5 Lf of diphtheria and 5 BU of tetanus components) for diphtheria and tetanus revaccination of children aged from 1 to 11 years with allergic reactivity provided a marked immunological efficacy with an insignificant reactogenicity. The revaccinating effect was also marked in case of a prolonged lapse of time--up to 10 years (observations period) from the last vaccination. Children with allergic reactivity with contraindications to the administration of APDT vaccine and APDT vaccine and ADT-toxoid of conventional composition can be effectively revaccinated with ADT-toxoid with decreased antigen content on condition of careful clinical observation.
