Vaccination status is conventionally measured by up-to-date coverage. This method does not take in to account whether the vaccines were received at the correct age and interval which is essential for optimal disease protection. Sri Lanka - a lower middle-income country in the Indian Ocean, has previously presented with high vaccination coverage for all childhood vaccines. However, few studies investigating timeliness of vaccinations have until now been carried out in Sri Lanka. Aim: This study was carried out to investigate the individual coverage and age appropriateness of vaccination, in two different demographic settings in Anuradhapura district, Sri Lanka. The study of cross-sectional descriptive design included 633 children born in 2011. Public Health Midwives kept hand-written documentation of the birth and vaccination dates on each child in her geographic area. Vaccination ages were then compared to the timelines of vaccination provided by the Epidemiology Unit of Sri Lanka. The vaccination coverage for all antigens was 97.5% (94.2-99.7%) at age 5-6 years. Timeliness of doses was between 65.0 and 88.6 % (median 80.7%; 65.0-88.6) and significantly lower in the urban population compared to the rural. The present study shows that the vaccine coverage in both urban and rural areas in Sri Lanka was high and that the timeliness predominantly followed national recommendations.
疫苗接种状况传统上是通过最新覆盖率来衡量的。这种方法没有考虑疫苗是否是在正确的年龄和间隔接种的，而这对于实现最佳疾病防护至关重要。斯里兰卡是印度洋上的一个中低收入国家，此前所有儿童疫苗的接种覆盖率都很高。然而，到目前为止，在斯里兰卡很少有研究调查疫苗接种的及时性。目的：本研究旨在调查斯里兰卡阿努拉德普勒区两种不同人口环境下疫苗接种的个体覆盖率和年龄适宜性。这项横断面描述性设计研究纳入了633名2011年出生的儿童。公共卫生助产士对其所在地理区域内每个儿童的出生和疫苗接种日期进行手写记录。然后将疫苗接种年龄与斯里兰卡流行病学部门提供的疫苗接种时间表进行比较。5至6岁儿童所有抗原的疫苗接种覆盖率为97.5%（94.2 - 99.7%）。各剂次的及时性在65.0%至88.6%之间（中位数80.7%；65.0 - 88.6），城市人口的及时性显著低于农村人口。本研究表明，斯里兰卡城乡地区的疫苗接种覆盖率都很高，且及时性主要遵循国家建议。
