Abstract

In September 2023, France was one of the first countries that started a national immunisation campaign with nirsevimab, a new monoclonal antibody against respiratory syncytial virus (RSV). Using data from a network of paediatric intensive care units (PICUs), we aimed to estimate nirsevimab effectiveness against severe cases of RSV bronchiolitis in France. We conducted a case–control study based on the test-negative design and included 288 infants reported by 20 PICUs. We estimated nirsevimab effectiveness at 75.9% (48.5–88.7) in the main analysis and 80.6% (61.6–90.3) and 80.4% (61.7–89.9) in two sensitivity analyses. These real-world estimates confirmed the efficacy observed in clinical studies.

2023 年 9 月至 2024 年 1 月期间，Nirsevimab 对法国儿科重症监护病房住院呼吸道合胞病毒支气管炎病例的疗效。

2023 年 9 月，法国成为首批开始使用 nirsevimab（一种新型抗呼吸道合胞病毒（RSV）单克隆抗体）进行全国免疫接种的国家之一。我们利用来自儿科重症监护病房（PICU）网络的数据，旨在估算涅舍维单抗对法国 RSV 支气管炎重症病例的疗效。我们进行了一项基于阴性试验设计的病例对照研究，纳入了 20 个 PICU 报告的 288 名婴儿。在主要分析中，我们估计 nirsevimab 的有效率为 75.9% (48.5-88.7)；在两项敏感性分析中，我们估计 nirsevimab 的有效率分别为 80.6% (61.6-90.3) 和 80.4% (61.7-89.9)。这些真实世界的估计值证实了临床研究中观察到的疗效。
