To estimate infant vaccination coverage in the French-speaking region of Belgium (Wallonia) and in the Brussels-Capital Region, two cross-sectional studies were performed in 2012. A face-to-face questionnaire was administered by trained investigators. The objective was to evaluate infant vaccination coverage retrospectively in 18- to 24-month-old children. These studies offered the opportunity to assess some factors influencing vaccine uptake in infants.
Approximately 99% of the children had received the first dose of IPV-DTaP, 90% the fourth dose, 94% the MMR vaccine, 97% the first dose of pneumococcal vaccine, and 90% the third dose. In both regions, when fitting a logistic model, the most associated factor was attendance at maternal and child clinics (MCH). No association was observed between vaccination coverage and the mother's level of education. For the last immunization session, where the mother was a Belgian native and when she worked more hours, child was better immunized, but only in Brussels.
Coverage for the fourth dose of hexavalent vaccine (DTaP-IPV-HBV/Hib) needs to be increased. Indeed, additional effort is needed to increase HIB and pertussis coverage rates because the herd immunity threshold for these two diseases has not been reached.
为估算比利时法语区（瓦隆尼亚）和布鲁塞尔首都大区的婴儿疫苗接种覆盖率，2012年开展了两项横断面研究。由经过培训的调查人员进行面对面问卷调查。目的是回顾性评估18至24个月大儿童的婴儿疫苗接种覆盖率。这些研究提供了评估一些影响婴儿疫苗接种因素的机会。
约99%的儿童接种了第一剂脊髓灰质炎灭活疫苗-白百破疫苗，90%接种了第四剂，94%接种了麻腮风疫苗，97%接种了第一剂肺炎球菌疫苗，90%接种了第三剂。在两个地区，拟合逻辑模型时，最相关的因素是妇幼保健门诊就诊情况。未观察到疫苗接种覆盖率与母亲教育水平之间存在关联。对于最后一次免疫接种，母亲为比利时本地人且工作时间较长时，孩子的免疫接种情况较好，但仅在布鲁塞尔是这样。
六价疫苗（白百破-脊髓灰质炎灭活疫苗-乙肝疫苗/ Hib）第四剂的接种覆盖率需要提高。确实，需要付出更多努力来提高Hib和百日咳的接种率，因为这两种疾病尚未达到群体免疫阈值。
