Childhood vaccination is one of the most successful public health interventions to improve life expectancy, decrease health care costs, and reduce the spread of preventable diseases. Using data from jurisdictional immunization information systems, vaccination coverage by age 24 months among children born during 2017-2021 in the U.S.-affiliated Pacific Islands was estimated for all vaccines included in jurisdictional programs. Progress toward the U.S. Healthy People 2030 and World Health Organization Immunization Agenda 2030 vaccination goals of ≥90% coverage by age 24 months with recommended vaccines was inconsistently met across jurisdictions. For example, coverage by age 24 months with ≥1 dose of measles, mumps, and rubella vaccine ranged from 68.2% to 91.6% by birth cohort in Federated States of Micronesia and from 87.4% to 96.6% in Palau; coverage with ≥4 doses of diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP) ranged from 39.6% to 60.6% in Federated States of Micronesia and from 73.4% to 85.4% in Palau. Coverage as of June 1, 2024, increased for all vaccines across all jurisdictions and birth cohorts, indicating catch-up vaccination after age 24 months. For example, coverage with ≥4 doses of DTaP by June 1, 2024, ranged from 74.0% to 84.4% in American Samoa by birth cohort and from 91.6% to 94.8% in Palau. This report is the first comprehensive analysis of trends in childhood vaccination coverage in the U.S.-affiliated Pacific Islands; data in this report can be used to determine where additional efforts are needed to assess reasons for delayed vaccination of children and strategies to mitigate vaccination delays, specific to each jurisdiction.

2017-2021 年出生的 24 个月儿童的疫苗接种覆盖率 - 美国附属太平洋岛屿。


儿童疫苗接种是提高预期寿命、降低医疗保健成本和减少可预防疾病传播的最成功的公共卫生干预措施之一。使用来自辖区免疫信息系统的数据，估计了 2017-2021 年在美国附属太平洋岛屿出生的儿童到 24 个月大的疫苗接种覆盖率，包括管辖计划中包括的所有疫苗。在实现美国 2030 年健康人群和世界卫生组织 2030 年免疫议程的疫苗接种目标方面取得的进展，即到 24 个月大时，推荐疫苗覆盖率达到 ≥90%，但各辖区之间的实现情况不一致。例如，在密克罗尼西亚联邦的出生队列中，到 24 个月大时，≥1 剂麻疹、腮腺炎和风疹疫苗的覆盖率在 68.2% 到 91.6% 之间，在帕劳从 87.4% 到 96.6% 不等;密克罗尼西亚联邦的 ≥4 剂白喉和破伤风类毒素以及无细胞百日咳疫苗 （DTaP） 的覆盖率为 39.6% 至 60.6%，帕劳为 73.4% 至 85.4%。截至 2024 年 6 月 1 日，所有司法管辖区和出生队列的所有疫苗覆盖率都有所增加，这表明在 24 个月大后进行了补种疫苗接种。例如，截至 2024 年 6 月 1 日，≥4 剂 DTaP 的覆盖率在美属萨摩亚按出生队列划分为 74.0% 至 84.4%，帕劳为 91.6% 至 94.8%。本报告首次全面分析了美国附属太平洋岛屿的儿童疫苗接种覆盖率趋势;本报告中的数据可用于确定在哪些方面需要付出额外努力来评估儿童疫苗接种延迟的原因以及缓解疫苗接种延迟的策略，具体适用于每个司法管辖区。
