摘要：

Background: There are limited data on influenza vaccine effectiveness (IVE) in preventing laboratory confirmed influenza illness among healthcare personnel (HCP). Methods: HCP with direct patient contact working full-time in hospitals were followed during three influenza seasons in Israel (2016-2017 to 2018-2019) and Peru (2016 to 2018). Trivalent influenza vaccines were available at all sites, except during 2018-2019 when Israel used quadrivalent vaccines; vaccination was documented by electronic medical records, vaccine registries, and/or self-report (for vaccinations outside the hospital). Twice-weekly active surveillance identified acute respiratory symptoms or febrile illness (ARFI); self-collected respiratory specimens were tested by real-time reverse transcription polymerase chain reaction (PCR) assay. IVE was 100 x 1-hazard ratio (adjusted for sex, age, occupation, and hospital). Results: Among 5,489 HCP who contributed 10,041 person-seasons, influenza vaccination coverage was 47% in Israel and 32% in Peru. Of 3,056 ARFIs in Israel and 3,538 in Peru, A or B influenza virus infections were identified in 205 (7%) in Israel and 87 (2.5%) in Peru. IVE against all viruses across seasons was 1% (95% confidence interval [CI] =-30%, 25%) in Israel and 12% (95% CI =-61%, 52%) in Peru. Conclusion: Estimates of IVE were null using person-time models during six study seasons in Israel and Peru. (c) 2021 Published by Elsevier Ltd.
