摘要：A mass BCG-vaccination campaign was undertaken in Aden Colony during February-May 1952 by WHO/UNICEF in co-operation with the Directorate of Medical Services. Over 31,000 persons (about one-fourth of the total population) were given an intradermal 5 TU test, and 22,000 returned for the reaction to be read. Of these, about one-third were classified as negative and all but a very few of them were given an intradermal injection of BCG vaccine. Of those vaccinated, over half were children of school-age. The results obtained in this campaign are described with particular reference to the number and size of tuberculin reactions, and the results of follow-up examinations in nearly 2,000 schoolchildren.
