[Tuberculous allergy in a population of 3-to-23-month-old children in Bangui (Central African Republic)]. / Etude de l'allergie tuberculinique dans une population d'enfants âgés de 3 à 23 mois à Bangui (Republique Centrafricaine).

ABSTRACT

In 1986, vaccinal allergy has been looked for by tuberculin RT 23 intradermal reaction within a random group of 354 Central African Children aged of 3 to 23 months and immunized in the Mother and Child Care Services in Bangui in the framework of the Enlarged Vaccination Program, with the same B.C.G. strain during their postnatal period. Percentage of intradermal reactions equivalent or superior to 6 mm get down with time, of progressive but fast mode from 56.2 p.c. in the age group of 3 to 5 months to 20.2 p.c. in the ones of 12 to 23 months. Nevertheless, the authors recommend B.C.G. immunization in urban milieu during the postnatal period because of the strong vaccinal protection one get, but recommend also a systematic booster injection during the second year of childhood.
