作者对两组婴儿接种b型流感嗜血杆菌(Hib)荚膜多糖(磷酸聚核糖基核糖醇,PRP)/白喉类毒素(D)联合菌苗(PRP-D),以评价最佳接种时间和次数.71名婴儿同时接种PRP-D和DPT菌苗.接种后仅出现轻微副反应.于接种前和接种后1～2个月采血,用放射免疫法(RIA)测定PRP抗体水平.第1组(3、5和7月龄接种)婴儿接种第1和第2针后,其PRP的抗体几何平均滴 The authors vaccinated two groups of infants with a combination of Hib capsular polysaccharide (polyglucosylpolyglycosylphosphate, PRP) / diphtheria toxoid (D) combined vaccine (PRP-D) to evaluate the optimal vaccination time And 71 infants were inoculated with PRP-D and DPT vaccine at the same time, there were only mild side effects after inoculation.Pre-vaccination and 1-2 months after inoculation, blood samples were collected for PRP antibody by radioimmunoassay (RIA) 1 group (3, 5 and 7 months old vaccination) infants after vaccination 1 and 2, the PRP antibody geometric mean drop
