BronchStartStop临床研究项目由PERUKI网络实施。BronchStart部分纳入537对母婴,含391例RSV阳性病例和146例RSV阴性对照;BrochStop为全国性、多中心、前瞻性、检测阴性病例对照研究,在37个医院地点开展。BronchStart结果显示,母亲在分娩前任何时间接种RSVpreF疫苗,预防婴儿住院的调整后有效性为58%(95% CI 28-75)。

要点

  • 母体RSVpreF疫苗在分娩前任何时间接种,预防婴儿住院的调整后有效性为58%(95% CI 28-75)。
  • BronchStart中,RSV阳性病例的母亲接种率19%,RSV阴性对照为41%。
  • BrochStop为全国多中心前瞻性检测阴性病例对照研究,覆盖37个医院地点。

核心结论

  • 在分娩前任何时间接种母体二价RSVpreF疫苗,预防婴儿住院的调整后有效性为58%(95% CI 28-75)。

研究设计与样本

  • BronchStart部分由PERUKI网络实施,纳入537对母婴,含391例RSV阳性病例和146例RSV阴性对照。
  • BrochStop为全国性、多中心、前瞻性、检测阴性病例对照研究,在37个医院地点开展。

主要发现

  • 73名(19%)RSV阳性病例的母亲和60名(41%)RSV阴性对照的母亲在分娩前接种了RSVpreF疫苗。
  • 调整后疫苗有效性为58%(95% CI 28-75),针对母亲在分娩前任何时间接种的婴儿。

关键数值与推荐

The BronchStartStop clinical research programme was delivered by the Paediatric Emergency Research in the UK and Ireland (PERUKI) network. In the BronchStart part of the study (Williams TC and Marlow R et al. Lancet Child Adolesc Health 2025; 9: 655–62. https://doi.org/10.1016/S2352-4642(25)00155-5 ), there were 537 mother–infant pairs recruited, where there were 391 respiratory syncytial virus (RSV)-positive infant cases and 146 RSV-negative infant controls. The mothers of 73 (19%) RSV-positive cases and 60 (41%) RSV-negative controls had received the maternal bivalent RSV prefusion F vaccine (RSVpreF) before delivery. The adjusted effectiveness of maternal RSVpreF vaccination for preventing infant hospitalisation was 58% (95% CI 28 to 75) for infants whose mothers were vaccinated at any time before delivery. O’Hagan et al ( Lancet Child Adolesc Health 2026; https://doi.org/10.1016/S2352-4642(26)00134-3 ) have now published the BrochStop study, which was a national, multicentre, prospective, test-negative, case-control study at 37 hospital sites (in the...
