OBJECTIVE
To estimate measles-mumps-rubella vaccination coverage, delay and loss to follow-up in children up to 24 months old living in Brazilian cities.
METHODS
Surveys and questionnaires with a retrospective cohort of live births in 2017-2018, analyzing vaccination coverage and sociodemographic data of children and families, based on vaccination card records and interviews.
RESULTS
Valid coverage of first dose was 90.0% (95%CI 88.9;91.0) and 81.1% for the second dose (95%CI 79.8;82.4). Delay for both doses was 23.2% (95%CI 21.9;24.5) and loss to follow-up was 10.8% (95%CI 9.9;11.8). Socioeconomic stratum A had the lowest vaccination coverage and the higher the child's birth order, the lower the vaccination coverage for the second dose. Children whose mothers had 13 to 15 years of education had higher vaccination coverage.
CONCLUSION
Coverage did not meet the recommended target. Differentiated strategies to resolve difficulties in access, misinformation, and vaccination hesitancy will help improve vaccination coverage.
目的
评估巴西城市中24个月及以下儿童的麻疹-腮腺炎-风疹疫苗接种覆盖率、延迟接种情况及失访情况。
方法
对2017 - 2018年出生队列进行回顾性调查并发放问卷，依据疫苗接种卡记录和访谈分析儿童及其家庭的疫苗接种覆盖率和社会人口学数据。
结果
首剂疫苗的有效接种覆盖率为90.0%（95%置信区间88.9；91.0），第二剂为81.1%（95%置信区间79.8；82.4）。两剂疫苗的延迟接种率为23.2%（95%置信区间21.9；24.5），失访率为10.8%（95%置信区间9.9；11.8）。社会经济阶层A的疫苗接种覆盖率最低，且孩子的出生顺序越高，第二剂疫苗的接种覆盖率越低。母亲受教育年限为13至15年的儿童疫苗接种覆盖率较高。
结论
接种覆盖率未达到推荐目标。采取差异化策略解决接种困难、错误信息及疫苗接种犹豫问题将有助于提高疫苗接种覆盖率。
