Abstract
OBJECTIVE: This study is to estimate the routine immunization coverage of China, and to analyse the effect factors. METHODS: The reported routine coverage data in 2005-2007 were collected through China Immunization information system. The estimated coverage method used in this study, which was recommended by the World Health Organization (WHO). RESULTS: The percentage of county reported routine immunization were 79.8%, 92.3% and 92.0% respectively in 2005-2007; the targeted population of routine immunization reported from China immunization information system were 123-140.6 million, the vaccinated population were between 91.3-139.5 million; reported routine immunization coverage of each vaccine dose varied from 89%-100%, and estimated coverage varied from 78%-94%. CONCLUSION: The reported and estimated routine immunization coverage increased year by year. However, there is still a large gap between the reported data and the estimated data. It is recognized that the birth cohort and the adjusted index from the WHO recommended method should be used carefully.
