The impact of a varicella vaccination program on disease in a large HMO population during 1996-1999 was assessed by multiple cross-sectional analyses of automated database records of vaccinations and varicella diagnoses for children (0-18 years). The cumulative proportion of the population vaccinated reached 73% among 2-year-olds, and 22% overall. An overall 49.7% reduction in varicella incidence was estimated to be attributable to an 18.5% point increase in the proportion of the population vaccinated.
通过对1996 - 1999年间大型健康维护组织（HMO）中0至18岁儿童的疫苗接种和水痘诊断自动数据库记录进行多次横断面分析，评估了水痘疫苗接种计划对疾病的影响。在2岁儿童中，接种疫苗的人群累计比例达到73%，总体为22%。据估计，水痘发病率总体降低49.7%可归因于接种人群比例提高了18.5个百分点。
