Abstract

A school-based campaign in Knox County, TN immunized 41% and 48% of school children with live attenuated influenza vaccine in 2005 and 2006, respectively. We computed the relative risk (RR) of a positive rapid influenza test in Knox compared to Knox-surrounding county children (controls) during five baseline and two campaign seasons. Among children aged <5 years, the RR for a positive test remained relatively constant throughout the study seasons. Among children aged 5-17 years (target population), the RR was 1 during baseline and declined by 21% (RR, 0.79; 95% CI, 0.59-1.05) and 27% (RR, 0.73; 95% CI, 0.60-0.87) during the first and second campaign season, respectively. These findings suggest a direct beneficial effect of the immunization campaign.

摘要

田纳西州诺克斯县开展的一项校园疫苗接种活动,在2005年和2006年分别为41%和48%的学童接种了减毒活流感疫苗。我们计算了在五个基线期和两个活动期内,诺克斯县儿童与周边县儿童(对照组)进行快速流感检测呈阳性的相对风险(RR)。在5岁以下儿童中,整个研究期间检测呈阳性的RR保持相对稳定。在5至17岁的儿童(目标人群)中,基线期RR为1,在第一个和第二个活动期分别下降了21%(RR,0.79;95%CI,0.59 - 1.05)和27%(RR,0.73;95%CI,0.60 - 0.87)。这些发现表明疫苗接种活动具有直接的有益效果。
