概括
一次复发疫苗可以恢复先前接种疫苗的人的乙型肝炎免疫力. 与标准疫苗相比,Heplisav-B的血清阳性率更高,确保了更好的乙型肝炎保护.
科学领域:
- 免疫学 免疫学 免疫学
- 疫苗学 疫苗学 疫苗学
- 公共卫生 公共卫生
背景情况:
- 乙型肝炎血清保护对医疗保健工作者至关重要,其定义为完整的免疫接种系列和足够的抗体标位 (抗HBs ≥10 mIU/mL).
- 维持足够的抗体水平对于长期保护B型肝炎病毒 (HBV) 感染至关重要.
研究的目的:
- 为了比较标准乙型肝炎疫苗单次增强剂量与Heplisav-B在年轻,健康,先前接种疫苗的个体中具有低抗体标位的疗效.
- 评估不同强剂疫苗在一组有记录的先前接种疫苗,但免疫反应不足的队列中实现的血清阳性率.
主要方法:
- 一项队列研究涉及242名参与者,他们有单次乙型肝炎疫苗接种系列的病史和抗HBs标位<10mIU/mL.
- 参与者接受了标准的乙型肝炎疫苗增剂或Heplisav-B作为单次增剂剂.
- 通过测量抗HBs抗体标位在补充疫苗接种后进行血清阳性评估.
主要成果:
- 赫普利萨夫-B助推剂的血清阳性率达到99.4% (95% CI,96.6%-100.0%).
- 标准的乙型肝炎疫苗增强剂达到92.7%的血清阳性率 (95% CI,84.8%-97.2%).
- 这两种疫苗类型都显示出在这个人群中诱导血清阳性的可能性很高.
结论:
- 标准乙型肝炎疫苗或Heplisav-B的单次增强剂量有效地恢复了先前接种疫苗的具有较低抗体标位的个体的血清保护.
- 赫普利萨夫-B似乎比标准疫苗更有效,在单次强剂后达到血清阳性.
- 这些发现支持使用复发疫苗来维持充足的乙型肝炎免疫力,特别是在医疗机构.
