A new tetravalent meningococcal polysaccharide vaccine containing groups A, C, W 135, and Y was administered to 40 healthy adults. The vaccine was well tolerated and bactericidal assay showed mean titre increases for the meningococcal polysaccharide groups A, C, W 135, and Y of 5.0, 7.8, 8.2, and 5.9 log(2) titre steps, respectively. The immunogenicity and side-effects of the vaccine were similar to those associated with monovalent and bivalent vaccines containing group A and C meningococcal polysaccharides.
一种包含A、C、W 135和Y群的新型四价脑膜炎球菌多糖疫苗被接种给40名健康成年人。该疫苗耐受性良好,杀菌试验显示,A、C、W 135和Y群脑膜炎球菌多糖的平均滴度分别增加了5.0、7.8、8.2和5.9个对数(2)滴度级。该疫苗的免疫原性和副作用与含A群和C群脑膜炎球菌多糖的单价及双价疫苗相似。
