改善预防和控制具有公共卫生意义的病毒、衣原体和立克次体疾病仍然是WHO活动的重要方面。虽然在一些国家用目前可获得的被证实安全有效的疫苗,有效地预防和控制了某些病毒性疾病,但在世界上许多地区,病毒性感染仍然是传染病总发病率中比例较高的病因。因此,很清楚,需要用疫苗改善对病毒性疾病的预防,且在许多实验室开展疫苗发展和病毒性疾病免疫机理的研究。最近在新的生物学技术启示下,特别是重组DNA技术及合成肽化学发展新的疫苗来看,用各种可获得的方法评价免疫反应特别重要。
Improving the prevention and control of public health-specific viruses, chlamydia and rickettsia diseases remains an important aspect of WHO’s activities. Although some viral diseases are effectively prevented and controlled in some countries with the currently available and proven safe and effective vaccines, viral infections are still a high proportion of the total incidence of infectious diseases in many parts of the world Etiology. Therefore, it is clear that vaccines are needed to improve the prevention of viral diseases and many laboratories are conducting vaccine development and research on the immune mechanisms of viral diseases. Recently, with the revelation of new biological technologies, especially the development of new vaccines for recombinant DNA technology and synthetic peptide chemistry, it is of particular importance to evaluate the immune response in various available ways.
