在发达及发展中国家,传染病仍然是人类健康的严重威胁。而大规模地、有效地控制传染病,特别是在第三世界,仍将依赖于成功的免疫接种策略。因此,探索疫苗生产新途径已成为人们关注的重要课题。现今采用的新方法主要有两类:(1)合成肽和单克隆抗体;(2)DNA操作,现分别简述如下。合成多肽疫苗抗生育力疫苗人绒毛膜促 In developed and developing countries, infectious diseases remain a serious threat to human health. Large-scale and effective control of infectious diseases, especially in the third world, will still depend on successful immunization strategies. Therefore, exploring new ways of vaccine production has become an important topic of concern. There are two main types of new methods used today: (1) synthetic peptides and monoclonal antibodies; and (2) DNA manipulations, each of which is briefly described below.
