The study aimed to evaluate vaccination coverage and factors associated with incomplete basic vaccination schedule at 12 months of age in 427 children aged 12-59 months in São Luis, Maranhão State, Brazil, 2006. This cross-sectional, population-based household survey used complex cluster sampling. Poisson regression with robust adjustment of variance was applied. Complete basic vaccination coverage was 71.9% for applied doses, 61.8% for valid doses, and 23.6% for correct doses. Hepatitis B and tetravalent vaccines showed higher percentages of doses on dates or at intervals lower than recommended. Percentages of delayed vaccination were high, except for BCG. Incomplete basic vaccination was more frequent in girls and children from low-income and black families. Racial, gender, and socioeconomic factors posed barriers to complete vaccination, thus emphasizing the need for policies to address such inequalities.
该研究旨在评估2006年巴西马拉尼昂州圣路易斯市427名12至59个月大儿童在12个月龄时的疫苗接种覆盖率以及与基础疫苗接种计划未完成相关的因素。这项基于人群的横断面家庭调查采用了复杂整群抽样方法。应用了具有稳健方差调整的泊松回归分析。基础疫苗接种的完整覆盖率方面，已接种剂量为71.9%，有效剂量为61.8%，正确剂量为23.6%。乙肝疫苗和四价疫苗在低于推荐日期或间隔时间接种的剂量比例较高。除卡介苗外，延迟接种的比例较高。基础疫苗接种未完成在女孩以及低收入和黑人家庭的儿童中更为常见。种族、性别和社会经济因素对完整接种疫苗构成了障碍，因此强调需要制定政策来解决此类不平等问题。
