Because college freshman who live in dormitories have a higher risk of meningococcal disease than other populations , the cdc has recommended that these students and their parents be educated about the availability of the meningococcal vaccine 因为住宿的大学新鲜人比其他人的风险高,因此疾病防治中心建议这些学生与家长们多了解一些有关双球菌脑膜炎疫苗的知识。
Locally , the incidence of meningococcal infections is low and about half of the meningococcal infections were caused by neisseria meningitidis serogroup b . the quadrivalent meningococcal vaccine does not confer protection against meningococcal infections caused by serogroup b , its duration of protection is short and it is relatively ineffective in children aged under 2 本港每年的脑膜炎双球菌感染病例中,约一半为b型的双球菌所引致。由于脑膜炎双球菌感染在本港并不常见,加上四价疫苗对b型的双球菌没有效用有效期间较短及对两岁以下儿童的效果较低,故此疫苗并不在本港免疫注射计划采用之列。
