呼吸道合胞病毒(RSV)、3型副流感病毒(PI 3V)和麻疹病毒可引起多种婴幼儿呼吸系统常见病。过去人们把研制麻疹疫苗的传统方法用于控制RS和PI 3V感染疫苗的制作,未能获得成功。为了鼓励研究人员应用新的生物工程技术对存在问题继续进行研究,世界卫生组织于1983年制定了“疫苗发展规划”。1986年6月26～27日,规划委员会的28位专家在加利福尼亚州的圣巴巴拉聚会,回顾了疫苗进展情况,并交流了信息。专家们讨论了近期在疫苗发展方面所取得的三项研制成果。
Respiratory syncytial virus (RSV), parainfluenza virus type 3 (PI 3V) and measles virus can cause common respiratory diseases in many infants and young children. In the past, the traditional method of developing measles vaccine was used to control the manufacture of vaccines against RS and PI 3V infections and failed to achieve success. In order to encourage researchers to continue studying the problems with new bioengineering technologies, WHO formulated the “Vaccine Development Plan” in 1983. On June 26-27, 1986, 28 experts from the Planning Commission met at Santa Barbara, California to review the progress of the vaccine and exchange information. Experts discussed three recent developments in vaccine development.
