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.
目的
评估巴西阿克里州里奥布朗库市城区内 2017-2018 年出生、24 个月以下儿童的疫苗接种覆盖率，分析儿童疫苗接种的障碍和犹豫因素。
方法
本研究于 2020 年至 2021 年开展了一项人群调查，评估了儿童的社会人口学特征和疫苗接种状况。
结果
在纳入的 451 名儿童中，疫苗接种覆盖率低于 80%。已接种的脑膜炎球菌 C 疫苗剂量（76.3%；95%CI 70.5；81.3）和及时接种的剂量（27.4%；95%CI 23.1；32.1）最低。关于疫苗犹豫，最常见的观点是“疫苗会引起严重的不良反应”（26.4%；95%CI 18.1；36.8）和“对于不再存在的疾病，不需要接种疫苗”（22%；95%CI 15.7；29.8）。疫苗供应不足是影响接种的主要障碍（86.6%；95%CI 71.8；94.3）。
结论
2017-2018 年出生的儿童疫苗接种覆盖率低于全剂量接种推荐目标，包括有效和及时接种的剂量。
