同时接种肺炎球菌疫苗 (PCV13和PPSV23) 与老年人接种单次或单次PPSV23疫苗相比,没有改善B细胞记忆反应. 所有的疫苗接种计划都被发现是安全的,并且耐受良好.
科学领域:
- 免疫学
- 疫苗学
- 老年医学
背景情况:
- 肺炎球菌疫苗,包括13肺炎球菌联合疫苗 (PCV13) 和23多糖疫苗 (PPSV23),对于预防老年人肺炎球菌疾病至关重要.
- 了解最佳的疫苗接种计划以最大限度地提高老年人的免疫反应对于公共健康至关重要.
研究的目的:
- 在老年人中,将PCV13和PPSV23同时接种的抗原特异性B细胞反应与顺序接种 (PCV13跟随PPSV23) 或单次PPSV23接种的反应进行比较.
- 在24个月内评估不同肺炎球菌疫苗的安全性和免疫性.
主要方法:
- 一个单一的随机试验,涉及60岁或以上的未接种疫苗的成年人.
- 参与者被分配为同时接种,连续接种或一次接种PPSV23疫苗.
- 主要测量结果是与基线相比,在接种后27至28周内,针对四种主要疫苗血清型的B细胞记忆的变化.
主要成果:
- 在所有四种疫苗血清类型中,在初级终点时,同时接种,顺序接种和单次接种疫苗组之间没有发现显著的B细胞反应差异.
- 在6个月后,与顺序接种组相比,同时接种疫苗的B细胞对血清型19A的记忆反应较低.
- 与同时接种或一次接种相比,连续接种导致24个月的IgG反应较高.
结论:
- 与老年人接种PCV13和PPSV23的同时接种疫苗并没有比分别接种PPSV23或单次接种疫苗提供更好的B细胞记忆反应.
- 所有评估的疫苗接种计划都显示出良好的安全性,没有报告严重的不良反应.
