2010年，广东省吸引了超过3100万流动人口。但很少有研究来估计完整且适龄的免疫覆盖率并确定流动儿童的危险因素。广东省 70 个村庄的 1610 名 12-59 个月的流动儿童接受了采访。获得人口统计特征、主要照顾者对免疫接种的知识和态度以及儿童的免疫接种史。对以下五种疫苗和整个系列（1:3:3:3:1 免疫系列）的 UTD 和适龄免疫率进行了评估：一剂 BCG、三剂 DTP、OPV 和 HepB、一剂 MCV。探讨了 1:3:3:3:1 免疫接种系列中不符合 UTD 的风险因素。每种抗原的UTD免疫率均在71%以上，但BCG、HepB、OPV、DPT和MCV的适龄免疫率分别仅为47.8%、45.1%、47.1%、46.8%和37.2%。第一个剂量最有可能在他们体内延迟。 1:3:3:3:1免疫系列的UTD免疫率和适龄免疫率分别为64.9%和12.4%。以下几个因素与 UTD 免疫显着相关。主要照顾者的决定因素是他们的职业、知识和对免疫接种的态度。孩子的决定因素是性别、户口、出生地、住宅楼和家庭收入。流动儿童的免疫覆盖率低得惊人，国家免疫安全局应密切监测。采取措施时应考虑主要照顾者和儿童的决定因素。需要制定战略，加强对初级护理人员的积极外展活动和健康教育，以提高他们的免疫覆盖率。
Guangdong province attracted more than 31 million migrants in 2010. But few studies were performed to estimate the complete and age-appropriate immunization coverage and determine risk factors of migrant children. 1610 migrant children aged 12–59 months from 70 villages were interviewed in Guangdong. Demographic characteristics, primary caregiver’s knowledge and attitude toward immunization, and child’s immunization history were obtained. UTD and age-appropriate immunization rates for the following five vaccines and the overall series (1:3:3:3:1 immunization series) were assessed: one dose of BCG, three doses of DTP, OPV and HepB, one dose of MCV. Risk factors for not being UTD for the 1:3:3:3:1 immunization series were explored. For each antigen, the UTD immunization rate was above 71%, but the age-appropriate immunization rates for BCG, HepB, OPV, DPT and MCV were only 47.8%, 45.1%, 47.1%, 46.8% and 37.2%, respectively. The 1st dose was most likely to be delayed within them. For the 1:3:3:3:1 immunization series, the UTD immunization rate and age-appropriate immunization rate were 64.9% and 12.4% respectively. Several factors as below were significantly associated with UTD immunization. The primary caregiver’s determinants were their occupation, knowledge and attitude toward immunization. The child’s determinants were sex, Hukou, birth place, residential buildings and family income. Alarmingly low immunization coverage of migrant children should be closely monitored by NIISS. Primary caregiver and child’s determinants should be considered when taking measures. Strategies to strengthen active out-reach activities and health education for primary caregivers needed to be developed to improve their immunization coverage.
