Abstract

We estimated XBB.1.5 vaccine effectiveness (VE) against symptomatic SARS-CoV-2 infection among adults aged ≥ 65 years during the 2023/2024 JN.1 lineage-predominant period in a European multi-country test-negative case–control study at primary care level. We estimated VE adjusted by study site, age, sex, chronic conditions and onset date. We included 220 cases and 1733 controls. The VE was 48% (95% CI: 12–71), 23% (95% CI: −11–48) and 5% (95% CI: −92–56) among those with symptom onset 1–5, 6–11, and ≥ 12 weeks after vaccination, respectively. XBB.1.5 vaccine provided short and moderate protection against JN.1 symptomatic infection.

欧洲 VEBIS 初级医疗多中心研究：XBB.1.5 疫苗对 JN.1 世系主导期老年人无症状 SARS-CoV-2 感染的有效性，2023 年 11 月 20 日至 2024 年 3 月 1 日。

在一项欧洲多国初级医疗水平的检测阴性病例对照研究中，我们估算了 XBB.1.5 疫苗对 2023/2024 年 JN.1 世系占主导地位期间年龄≥ 65 岁的成年人感染无症状 SARS-CoV-2 的有效性 (VE)。我们根据研究地点、年龄、性别、慢性病和发病日期对 VE 进行了调整。我们纳入了 220 例病例和 1733 例对照。在接种疫苗后 1-5 周、6-11 周和≥ 12 周出现症状的人群中，VE 分别为 48%（95% CI：12-71）、23%（95% CI：-11-48）和 5%（95% CI：-92-56）。XBB.1.5疫苗对JN.1无症状感染提供短期和中度保护。
