Background: To evaluate the effects of a wide range of individual- and community-level factors on migrant children's primary immunization. Methods: Migrant children aged 13–24 months (born from 1 June 2013 to 31 May 2014) were surveyed in Yiwu city, in June 2015. Social-demographic factors and vaccination records were collected. Five factors at community-level including community wealth, distance to the nearest immunization clinic, maternal education, antenatal clinic (ANC) visits, and hospital delivery were constructed. The relationship between individual- and community-level factors and a child's vaccination status for Chinese primary immunization were evaluated by logistic regression model and the adjusted odds ratio (AOR) with the p-values and 95% confidence interval (CI) were calculated. Results: The community wealth (aOR:1.4; 95% CI:1.1–2.7), the community maternal education (aOR:1.8; 95% CI:1.4–4.5), the community ANC visits (aOR:1.8; 95% CI:1.3–2.8), and the community hospital delivery (aOR:2.2; 95% CI:1.6–4.8) were positively associated with the completeness of primary immunization, while community distance to the nearest immunization clinic was negatively associated with the completeness of primary immunization (aOR:0.7; 95% CI:0.5–0.9). The coverage of completeness of primary immunization was higher among children living in rural areas than those living in urban areas (aOR:1.7; 95% CI: 1.3–3.1). Conclusions: In order to achieve better vaccination coverage among migrant children in Yiwu, as well as to close the gaps and disparities of acceptability and accessibility in childhood vaccination in urban areas, policy makers should design interventions based on the factors addressed in this study. © 2018, © 2018 Taylor & Francis.
