目前在美国批准使用的b型流感杆菌(Hib)结合菌苗(PRP-OMPC)为冻干制剂,内含15μg的Hib多糖(PRP)和250μg的脑膜炎球菌外膜蛋白复合物(OMPC),使用前需用Al(OH)3溶解。而液体PRP-OMPC菌苗有几个优点:(1)容易组成联合菌苗,减少注射次数;(2)使用前不需溶解;(3)节省时间
The currently approved Hib conjugate vaccine (PRP-OMPC) in the United States is a lyophilized preparation containing 15 μg of Hib polysaccharide (PRP) and 250 μg of meningococcal outer membrane protein complex (OMPC) Before using the need to use Al (OH) 3 dissolved. The liquid PRP-OMPC vaccine has several advantages: (1) easy to form a joint vaccine to reduce the number of injections; (2) do not need to be dissolved before use; (3) to save time
