The COVER scheme, a method for the rapid evaluation of vaccine coverage in England and Wales, is described. The primary aim of the scheme is to improve cover by providing health district vaccination programme coordinators with relevant timely information. Quarterly data were obtained from, analysed and promptly fed back to, 126 health districts on cohorts of children who had recently attained the target ages for receiving the selected sentinel vaccines; 18 months for third diphtheria and third pertussis and 2 years for measles. Although the data suggested that vaccination cover is improving, national performance still falls well short of 90%, the 1990 target set by the World Health Organisation for countries in Europe.
本文介绍了COVER计划，这是一种在英格兰和威尔士快速评估疫苗接种覆盖率的方法。该计划的主要目标是通过向卫生区疫苗接种计划协调员提供及时的相关信息来提高覆盖率。每季度从126个卫生区获取、分析并及时反馈有关最近达到选定哨点疫苗接种目标年龄儿童队列的数据；白喉第三针和百日咳第三针为18个月，麻疹为2岁。尽管数据表明疫苗接种覆盖率正在提高，但全国的表现仍远低于90%，这是世界卫生组织为欧洲国家设定的1990年目标。
