Abstract

The safety and immunogenicity of a high molecular weight polysaccharide from immunotype 1 Pseudomonas aeruginosa were tested in a dose response fashion in adult volunteers. The vaccine lacked toxicity and pyrogenicity for experimental animals. Doses of 50, 75, 150, or 250 microgram were given to groups of individuals as a single dose subcutaneous injection. Doses of 150 and 250 microgram were associated with a significant rise in binding and opsonic antibody at 2 wk postimmunization. Titers remained unchanged for up to 6 mo. The vaccine was almost devoid of toxicity, eliciting no more than a slightly sore and tender arm at the site of injection. High molecular weight polysaccharide antigen appears to induce a good immune response following vaccination that is effective in mediating opsonophagocytic killing of live P. aeruginosa organisms.

摘要

在成年志愿者中以剂量反应方式测试了1型铜绿假单胞菌高分子量多糖的安全性和免疫原性。该疫苗对实验动物无毒性和致热原性。将50、75、150或250微克剂量作为单剂量皮下注射给予不同组的个体。150和250微克剂量在免疫后2周时与结合抗体和调理素抗体的显著升高相关。滴度在长达6个月内保持不变。该疫苗几乎没有毒性,仅在注射部位引起手臂轻微疼痛和压痛。高分子量多糖抗原在接种疫苗后似乎能诱导良好的免疫反应,有效地介导对活铜绿假单胞菌的调理吞噬杀伤作用。
