To estimate vaccination coverage in children born between 2017-2018, living in urban areas of state capitals, the Federal District and 12 inland municipalities in Brazil, and to identify associated factors.
This was a household survey conducted between 2020-2022, among children up to 24 months old. Vaccination coverage was estimated according to family, maternal and child characteristics.
Among the 37,801 children in the sample, complete coverage (doses administered) was 60.1% (95%CI 58.6;61.6) and 6.1% (95%CI 5.4;7.0) had not received any vaccines. Coverage was lower among children of mothers with lower level of education (OR = 0.70; 95%CI 0.54;0.90) and in those who experienced delays in receiving any vaccine by 6 months old (OR = 0.28; 95%CI 0.24;0.32).
Vaccination coverage is below the expected levels. Effective communication strategies are needed to reinforce the importance of routine vaccination, prevent delays and abandonment of the vaccination schedule, in order to recover the high coverage levels achieved in past decades.
估计 2017-2018 年出生、居住在巴西州府城市、联邦区和 12 个内陆城市的儿童的疫苗接种覆盖率，并确定相关因素。
这是一项 2020-2022 年进行的家庭调查，对象为 24 个月以下的儿童。根据家庭、母婴特征估计疫苗接种覆盖率。
在 37801 名样本儿童中，完全接种（已接种剂量）率为 60.1%（95%CI 58.6;61.6），6.1%（95%CI 5.4;7.0）未接种任何疫苗。母亲教育程度较低的儿童（OR=0.70；95%CI 0.54;0.90）和在 6 个月大时任何疫苗接种延迟的儿童（OR=0.28；95%CI 0.24;0.32）的接种率较低。
疫苗接种覆盖率低于预期水平。需要有效的沟通策略来强调常规疫苗接种的重要性，以防止疫苗接种计划的延迟和中断，从而恢复过去几十年实现的高覆盖率水平。
