Abstract

Objective: To estimate vaccination coverage, identify barriers and hesitancy to vaccinating children up to 24 months, born between 2017-2018, living in the urban area of Rio Branco, Acre, Brazil.

Methods: Population survey carried out from 2020 to 2021, which assessed sociodemographic characteristics and vaccination status among children.

Results: Among 451 included children, vaccination coverage was below 80%. Meningococcal C vaccine had the lowest coverage for administered doses (76.3%; 95%CI 70.5;81.3) and doses on time (27.4%; 95%CI 23.1;32.1). The statements "vaccines cause serious adverse reactions" (26.4%; 95%CI 18.1;36.8) and "you don't need vaccination for diseases that no longer exist" (22%; 95%CI 15.7;29.8) were the most frequent regarding vaccination hesitancy. Lack of vaccines was the main barrier to care (86.6%; 95%CI 71.8;94.3).

Conclusion: Vaccination coverage in children born in 2017-2018 was below the target recommended for the full schedule of administered doses, both valid and timely administered.

24 个月以下儿童的疫苗接种覆盖率、障碍和疫苗接种犹豫：亚马孙河流域西部一个州首府的人口调查。

目的估算巴西阿克里省里约布兰科城区 2017-2018 年间出生的 24 个月以下儿童的疫苗接种覆盖率，确定接种障碍和犹豫不决的原因：2020年至2021年开展的人口调查，评估了儿童的社会人口特征和疫苗接种情况：在451名儿童中，疫苗接种率低于80%。在接种剂量（76.3%；95%CI 70.5;81.3）和按时接种剂量（27.4%；95%CI 23.1;32.1）方面，C 型脑膜炎球菌疫苗的接种率最低。关于疫苗接种犹豫不决，最常见的说法是 "疫苗会引起严重不良反应"（26.4%；95%CI 18.1；36.8）和 "不需要接种已不存在的疾病"（22%；95%CI 15.7；29.8）。缺乏疫苗是护理的主要障碍（86.6%；95%CI 71.8;94.3）：2017-2018年出生儿童的疫苗接种覆盖率低于建议的目标，未达到有效和及时接种的全部接种剂量。
