Abstract

Fijian infants aged 6 weeks were stratified by ethnicity and randomized to receive 0, 1, 2, or 3 PCV-7 doses with or without the 23-valent pneumococcal polysaccharide vaccine (PPV-23) at 12 months. Strong booster effects for all 7 PCV-7 serotypes were elicited, and for 4/7 serotypes these responses were highest in the single PCV-7 group. There were fourfold rises in GMC for all non-PCV-7 serotypes. By 17 months the PPV-23 group still had significantly higher GMC (each p<0.001) for all serotypes. The PPV-23 was well tolerated and induced excellent responses for all serotypes which were greatest in the single PCV-7 group.

摘要

6 周龄斐济婴儿按种族分层,随机分为接受 0、1、2 或 3 剂 PCV-7 加或不加 12 个月时的 23 价肺炎球菌多糖疫苗(PPV-23)组。所有 7 种 PCV-7 血清型均引起强烈的增强效应,4/7 种血清型在单剂 PCV-7 组的反应最高。所有非 PCV-7 血清型的 GMC 均有 4 倍升高。到 17 个月时,PPV-23 组所有血清型的 GMC 仍显著较高(p<0.001)。PPV-23 耐受性良好,引起所有血清型的良好反应,在单剂 PCV-7 组最大。
