The early impact of the expanded programme on immunization (EPI) in reducing morbidity from diphtheria was evaluated in the province of Yogyakarta, Java, Indonesia. Since 1980, coverage of two doses of diphtheria-tetanus-pertussis (DTP) immunization has been greater than 60% in Yogyakarta. The morbidity rate for diphtheria for children aged 0-4 years decreased from 4.3 per 100 000 population in 1978-79 to 1.7 per 100 000 in 1981-82, a reduction of 60%. In contrast, the morbidity rate for children aged 5-9 years remained relatively constant over the 5-year period. The EPI programme has therefore had a demonstrable effect on 0-4-year-olds in Yogyakarta.
在印度尼西亚爪哇省的日惹市，对扩大免疫规划（EPI）在降低白喉发病率方面的早期影响进行了评估。自1980年以来，日惹市两剂白喉-破伤风-百日咳（DTP）疫苗的免疫接种覆盖率一直高于60%。0至4岁儿童白喉发病率从1978 - 1979年的每10万人口4.3例降至1981 - 1982年的每10万人口1.7例，降幅达60%。相比之下，5至9岁儿童的发病率在这5年期间保持相对稳定。因此，扩大免疫规划项目对日惹市0至4岁儿童产生了明显效果。
