OBJECTIVES Rotavirus vaccination has 87% to 100% effectiveness against severe rotavirus acute gastroenteritis (AGE) in healthy infants in high-income countries. Little is known whether infants with medical risk conditions (MRCs) are equally protected and if the vaccine is equally well tolerated. We conducted a quasi-experimental prospective multicenter before-after cohort study to assess the vaccine effectiveness (VE) and safety profile of the human rotavirus vaccine (HRV) among MRC infants that required prolonged or frequent postnatal care. METHODS The Netherlands has no national rotavirus immunization program, but HRV was implemented in routine care for MRC infants in 13 Dutch hospitals. Participants in the before and after cohort, HRV unvaccinated and vaccinated, respectively, were followed for occurrence of (rotavirus) AGE. VE of at least 1 dose was estimated by using time-to-event analysis for severe rotavirus AGE. Vaccine-related serious adverse event (AEs) after HRV were retrieved systematically from medical charts. Solicited AEs after vaccinations were prospectively collected and compared between vaccination time points with or without HRV. RESULTS In total, 1482 high-risk infants with MRC were enrolled, including 631 in the before and 851 in the after cohorts; 1302 infants were premature (88.3%), 447 were small for gestational age (30.2%), and 251 had at least 1 congenital disorder (17.0%). VE against severe rotavirus AGE was 30% (95% confidence interval [CI]: -36% to 65%). Overall, the observed number of rotavirus hospitalizations was low and not significantly different between the cohorts (2 and 2, respectively). The rate of vaccine-related serious AE was 0.24 per 100 vaccine doses. The adjusted risk ratio for any AE after HRV vaccination compared with other routine vaccinations was 1.09 (95% CI: 1.05 to 1.12) for concomitant administration and 0.91 (95% CI: 0.81 to 0.99) for single HRV administration. Gastrointestinal AEs were 10% more frequent after HRV. CONCLUSIONS In contrast to previous findings among healthy term infants, in routine use, HRV offered limited protection to vulnerable medical risk infants. HRV is generally well tolerated in this group in single administration, but when coadministered with routine vaccines, it is associated with higher risk of (mostly gastrointestinal) AE. Our study highlights the importance of studying vaccine performance in subgroups of medically vulnerable infants.

轮状病毒疫苗在患有高危疾病的婴儿中的安全性和有效性。

目标 在高收入国家,轮状病毒疫苗接种对健康婴儿的严重轮状病毒急性胃肠炎 (AGE) 有 87% 至 100% 的有效性。尚不清楚患有医疗风险状况 (MRC) 的婴儿是否受到同等保护,以及疫苗是否具有同样良好的耐受性。我们进行了一项准实验性前瞻性多中心前后队列研究,以评估人类轮状病毒疫苗 (HRV) 在需要长期或频繁产后护理的 MRC 婴儿中的疫苗有效性 (VE) 和安全性。方法 荷兰没有国家轮状病毒免疫计划,但在 13 家荷兰医院对 MRC 婴儿的常规护理中实施了 HRV。分别跟踪未接种和接种 HRV 前后队列的参与者(轮状病毒)AGE 的发生情况。通过使用严重轮状病毒 AGE 的事件时间分析估计至少 1 剂的 VE。从病历中系统检索 HRV 后疫苗相关的严重不良事件 (AE)。前瞻性收集疫苗接种后征求的 AE,并在有或没有 HRV 的疫苗接种时间点之间进行比较。结果共纳入MRC高危婴儿1482例,其中前后队列631例,后队列851例;早产儿 1302 人(88.3%),小于胎龄儿 447 人(30.2%),251 人至少有 1 种先天性疾病(17.0%)。针对严重轮状病毒 AGE 的 VE 为 30%(95% 置信区间 [CI]:-36% 至 65%)。总体而言,观察到的轮状病毒住院次数很低,两组之间没有显着差异(分别为 2 和 2)。疫苗相关的严重 AE 发生率为 0。每 100 剂疫苗中有 24 剂。与其他常规疫苗接种相比,HRV 疫苗接种后任何 AE 的调整风险比对于同时给药为 1.09(95% CI:1.05 至 1.12),对于单一 HRV 给药为 0.91(95% CI:0.81 至 0.99)。HRV 后胃肠道 AE 的发生率增加了 10%。结论 与之前在健康足月婴儿中的发现相反,在常规使用中,HRV 对易受医疗风险影响的婴儿提供的保护有限。HRV 在该组中单次给药时通常具有良好的耐受性,但当与常规疫苗共同给药时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。与其他常规疫苗接种相比,HRV 疫苗接种后任何 AE 的调整风险比对于同时给药为 1.09(95% CI:1.05 至 1.12),对于单一 HRV 给药为 0.91(95% CI:0.81 至 0.99)。HRV 后胃肠道 AE 的发生率增加了 10%。结论 与之前在健康足月婴儿中的发现相反,在常规使用中,HRV 对易受医疗风险影响的婴儿提供的保护有限。HRV 在该组中单次给药时通常具有良好的耐受性,但当与常规疫苗共同给药时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。与其他常规疫苗接种相比,HRV 疫苗接种后任何 AE 的调整风险比对于同时给药为 1.09(95% CI:1.05 至 1.12),对于单一 HRV 给药为 0.91(95% CI:0.81 至 0.99)。HRV 后胃肠道 AE 的发生率增加了 10%。结论 与之前在健康足月婴儿中的发现相反,在常规使用中,HRV 对易受医疗风险影响的婴儿提供的保护有限。HRV 在该组中单次给药时通常具有良好的耐受性,但当与常规疫苗共同给药时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。99) 用于单一 HRV 给药。HRV 后胃肠道 AE 的发生率增加了 10%。结论 与之前在健康足月婴儿中的发现相反,在常规使用中,HRV 对易受医疗风险影响的婴儿提供的保护有限。HRV 在该组中单次给药时通常具有良好的耐受性,但当与常规疫苗共同给药时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。99) 用于单一 HRV 给药。HRV 后胃肠道 AE 的发生率增加了 10%。结论 与之前在健康足月婴儿中的发现相反,在常规使用中,HRV 对易受医疗风险影响的婴儿提供的保护有限。HRV 在该组中单次给药时通常具有良好的耐受性,但当与常规疫苗共同给药时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。但是当与常规疫苗共同接种时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。但是当与常规疫苗共同接种时,它与更高的(主要是胃肠道)AE 风险相关。我们的研究强调了在医学上易受伤害的婴儿亚组中研究疫苗性能的重要性。
