Purified meningococcal polysaccharides were administered to army recruits. No adverse reactions were observed in 145 men who received group C polysaccharide, and in 53 men who were injected with group A polysaccharide. Hemagglutinating and bactericidal activity developed in the sera of all individuals with the exception of two recruits injected with A polysaccharide. During the 6 wk period of observation, the proportion of unvaccinated recruits who acquired group C meningococci in the three companies studied was 38, 42, and 69 per cent. A significantly lower proportion of the individuals vaccinated with group C polysaccharide acquired group C meningococci; 4.6, 24, and 31 per cent respectively.
将纯化的脑膜炎球菌多糖给予新兵。接受C群多糖的145名男性和注射A群多糖的53名男性均未观察到不良反应。除两名注射A群多糖的新兵外,所有个体血清中均出现了血凝和杀菌活性。在6周的观察期内,在所研究的三个连队中,未接种疫苗的新兵感染C群脑膜炎球菌的比例分别为38%、42%和69%。接种C群多糖疫苗的个体感染C群脑膜炎球菌的比例明显较低,分别为4.6%、24%和31%。
