Abstract

COVID-19 vaccination recommendations include healthcare workers (HCWs). We measured COVID-19 vaccine effectiveness (CVE) of the autumn 2023 dose against laboratory-confirmed SARS-CoV-2 infection in a prospective cohort study of 1,305 HCWs from 13 European hospitals. Overall CVE was 22% (95% CI: -17 to 48), 49% (95% CI: -8 to 76) before and -11% (95% CI: -84 to 34) after the start of BA.2.86/JN.1 predominant circulation. Autumn 2023 COVID-19 vaccination led to a moderate-to-low reduction in SARS-CoV-2 infection incidence in HCWs. Monitoring of CVE is crucial for COVID-19 prevention.

2023年秋季COVID-19疫苗在医院医护人员中的有效性：VEBIS医护人员疫苗有效性队列研究的结果，七个欧洲国家，2023/24季。

COVID-19 疫苗接种建议包括医护人员 (HCW)。我们在一项前瞻性队列研究中测量了 2023 年秋季接种的 COVID-19 疫苗对实验室确诊的 SARS-CoV-2 感染的有效性 (CVE)，研究对象是来自欧洲 13 家医院的 1305 名医护人员。总体 CVE 为 22%（95% CI：-17 至 48），在 BA.2.86/JN.1 开始流行之前为 49%（95% CI：-8 至 76），之后为-11%（95% CI：-84 至 34）。2023 年秋季接种 COVID-19 疫苗后，人机工程人员的 SARS-CoV-2 感染率略有下降。监测 CVE 对预防 COVID-19 至关重要。
