We conducted a hospital-based test-negative study in Hong Kong to estimate influenza vaccine effectiveness (VE) for the winter of 2017/18. The interim analysis included data on 1,078 children admitted between 4 December 2017 and 31 January 2018 with febrile acute respiratory illness and tested for influenza. We estimated influenza VE at 66% (95% confidence interval (CI): 43-79) overall, and 65% (95% CI: 40-80) against influenza B, the dominant virus type (predominantly B/Yamagata).
我们在香港进行了一项基于医院的病例对照研究，以估计 2017/18 年冬季的流感疫苗效力（VE）。中期分析包括了 2017 年 12 月 4 日至 2018 年 1 月 31 日期间因发热性急性呼吸道疾病住院并接受流感检测的 1078 名儿童的数据。我们估计总体流感 VE 为 66%（95%置信区间（CI）：43-79），对乙型流感的 VE 为 65%（95% CI：40-80），乙型流感是主要的病毒类型（主要为 B/Yamagata）。
