Abstract

Objective: To analyze factors associated with full vaccination coverage with valid doses, in children from four state capitals and three other cities in Southeast Brazil.

Method: Analysis of a population survey conducted in 2020-2021, with a sample stratified according to socioeconomic levels of children born in 2017-2018, with data collected through photographic records of their vaccination cards. Odds ratios (OR) and 95% confidence intervals (95%CI) for full vaccination coverage were estimated based on the characteristics of the family, mother and child.

Results: Among 8703 children, lowest coverage occurred in strata A and B (OR=0.39; 95%CI 0.23;0.67 and OR=0.38; 95%CI 0.25;0.58); in consumption level A/B (OR=0.38; 95CI% 0.28;0.52); among those with income >BRL8000/month (OR=0.23; 95%CI 0.12;0.42); in children of mothers with higher education (OR=0.47; 95%CI 0.32;0.71); in children not vaccinated exclusively in the public service (OR=0.37; 95%CI 0.26;0.51) and in children with a vaccination delay of up to 6 months (OR=0.28; 95%CI 0.22;0.37).

Conclusion: Coverage did not reach the targets for controlling vaccine-preventable diseases and was negatively associated with higher socioeconomic status.

Main results: Vaccination coverage for the full schedule with valid doses was very low, putting the control of vaccine-preventable diseases at risk in the four state capitals and three other cities in the interior region of Southeast Brazil.

Implications for services: Brazilian National Health System managers and workers need to know the factors associated with low vaccination coverage and increased risk of abandoning the schedule, access problems and National Immunization Program difficulties.

Perspectives: Understanding determinants of low vaccination coverage provides support for the discussion and design of effective public policies to address barriers and qualify health services for vaccination.

在巴西东南部地区2017年和2018年活产队列中，有效剂量的疫苗接种完全覆盖。

目的：分析巴西东南部4个州首府和3个其他城市儿童有效剂量疫苗完全接种覆盖率的相关因素。方法：对2020-2021年的人口调查进行分析，根据2017-2018年出生的儿童的社会经济水平分层，通过疫苗接种卡的照片记录收集数据。根据家庭、母亲和儿童的特征估计完全疫苗接种覆盖率的优势比（OR）和95%置信区间（95% ci）。结果：8703名儿童中，A层和B层覆盖率最低(OR=0.39；95%CI 0.23;0.67， OR=0.38；95%可信区间0.25;0.58);消费水平A/B (OR=0.38)；95 ci % 0.28, 0.52);月收入为8000巴西雷亚尔（OR=0.23）；95%可信区间0.12;0.42);母亲受过高等教育的儿童(OR=0.47；95%可信区间0.32;0.71);在没有完全在公共服务部门接种疫苗的儿童中(OR=0.37；95%CI 0.26;0.51)和疫苗接种延迟长达6个月的儿童(OR=0.28；95%可信区间0.22;0.37)。结论：覆盖率未达到控制疫苗可预防疾病的目标，且与较高的社会经济地位呈负相关。主要成果：在巴西东南部内陆地区的四个州首府和其他三个城市，有效剂量的疫苗接种覆盖率非常低，危及疫苗可预防疾病的控制。对服务的影响：巴西国家卫生系统管理人员和工作人员需要了解与疫苗接种覆盖率低和放弃计划风险增加、获取问题和国家免疫规划困难相关的因素。观点：了解疫苗接种覆盖率低的决定因素为讨论和设计有效的公共政策提供支持，以解决疫苗接种障碍并使卫生服务合格。
