Abstract

Opsonophagocytic activity (OPA) was measured following reduced infant doses of 7-valent pneumococcal conjugate vaccine (PCV-7) with or without 23-valent pneumococcal polysaccharide vaccine (PPV-23) at 12 months, and subsequent re-exposure to a small dose of pneumococcal polysaccharide antigens (mPPS) at 17 months. Fijian infants were randomized to receive 0, 1, 2, or 3 PCV-7 doses. Half received PPV-23 at 12 months and all received mPPS at 17 months. OPA was performed on up to 14 serotypes. Three and 2 PCV-7 doses resulted in similar OPA for most PCV-7 serotypes up to 9 months and for half of the serotypes at 12 months. A single dose improved OPA compared with the unvaccinated group. PPV-23 significantly improved OPA for all serotypes tested but in general, was associated with diminished responses following re-challenge.

摘要

调理吞噬活性(OPA)在婴儿接受 7 价肺炎球菌结合疫苗(PCV-7)低剂量接种,无论是否同时接种 23 价肺炎球菌多糖疫苗(PPV-23)后 12 个月,以及随后在 17 个月时再次接触小剂量肺炎球菌多糖抗原(mPPS)时进行测量。斐济婴儿被随机分为接受 0、1、2 或 3 剂 PCV-7。一半的婴儿在 12 个月时接种 PPV-23,所有婴儿在 17 个月时接种 mPPS。OPA 最多针对 14 种血清型进行。对于大多数 PCV-7 血清型,3 剂和 2 剂 PCV-7 接种在 9 个月时产生了相似的 OPA,在 12 个月时对一半的血清型产生了相似的 OPA。与未接种疫苗的组相比,1 剂疫苗可改善 OPA。PPV-23 显著提高了所有测试血清型的 OPA,但通常与再次挑战后的反应减弱有关。
