由流感嗜血杆菌B型(RiB)多糖(PS)胶囊组成的疫苗最近在美国获得许可。这种疫苗在预防两岁及以上儿童的侵袭性肋部疾病方面是安全有效的,但对患病风险最大的幼儿无效。PS疫苗也可能在某些亚群人群中预防疾病无效,这些亚群在遗传上具有增加的疾病风险,并显示对免疫的抗体应答受损。因此,需要考虑新的战略。目前,正在评估几种新的Rib PS-蛋白缀合物疫苗。这些疫苗的制备方法、载体蛋白和PS大小不同。与普通Hib PS疫苗相比,结合疫苗在婴儿中具有免疫原性,并在重新注射疫苗后引起PS抗体的可加强增加。然而,一些不到六个月的婴儿没有反应。为了对所有婴儿提供保护,可能有必要进一步修改结合疫苗。一种方法是使用外膜蛋白(aMP)作为疫苗组分。已经从Hib中纯化了五种主要的aMP,其中三种,P1(50千道尔顿[kDa])、P2(37 kDa)和P6(16 kDa),含有能够在实验动物中引发菌株特异性保护性抗体的抗原。总之,PS-蛋白缀合物疫苗在预防婴儿肋部疾病方面具有巨大的前景,但需要进一步的工作来确定最佳载体蛋白、PS大小和偶联方法。还需要关于遗传因素是否影响对这些疫苗的反应的信息。
A vaccine consisting of the polysaccharide (PS) capsule ofHaemophilus influenzaetype b (Rib) has recently been licensed in the United States. This vaccine is safe and effective in preventing invasive Rib disease in children two years of age and older, but it is ineffective in younger children, the group at greatest risk of disease. The PS vaccine also may be ineffective in preventing disease in certain subgroups of the population that are genetically at increased risk of disease and show impaired antibody responses to immunization. Thus, new strategies need to be considered. Currently, several new Rib PS-protein conjugate vaccines are being evaluated. These vaccines differ in their method of preparation, carrier protein, and PS size. In contrast to the plain Hib PS vaccine, conjugate vaccines are immunogenic in infants and elicit boostable increases in antibody to PS upon reinjection of vaccine. However, some infants less than six months of age do not respond. To confer protection on all infants, it may be necessary to modify further the conjugate vaccines. One approach is to use outer membrane proteins (aMPs) as vaccine components. Five major aMPs have been purified from Hib, and three, PI (50 kilodalton [kDa]), P2 (37 kDa), and P6 (16 kDa), contain antigens capable of eliciting strain-specific protective antibodies in experimental animals. In summary, PS-protein conjugate vaccines hold enormous promise for the prevention of Rib disease in infants, but further work is needed to define the optimal carrier protein, PS size, and method of coupling. Information is also needed on whether genetic factors influence responses to these vaccines.
