Abstract: Objective The study was conducted to give an insight into the immunization coverage rate among migrant children in Hefei City, providing evidence for the management of immunization for migrant children. Methods Fifteen 0-7 aged migrant children were randomly surveyed in two migrant-gathered areas in each blocks of the city with uniform questionnaires. Results A total of 120 migrant children were surveyed, the licensed rate being 88.3%, and BCG scar rate 72.5%. The inoculation rate of five vaccinations BCG, DPT, OPV, MV and HBV, was 69.2%. The inoculation rates of epidemic meningitis and Japanese B encephalitis were 58.3% and 54.2%, respectively, while those of the other two vaccinations were 36.7%. Most of the migrant children flowed into the city from the other cities, as well as the three counties of Hefei. The education background of 77.5% of their parents was below junior school, most of who engaged in trade or as laborers, and had little knowledge of planned immunization. Conclusion The immunization coverage rate of migrant children in Hefei was low. Multiple ways of inoculation should be adopted while strengthening the education for parents of migrant children. Multi-sectoral collaboration was a suggested way in favor of the active immunization work for migrant children.
