Rocky Mountain spotted fever vaccine was produced from rickettsiae grown in chicken embryo cells in roller bottle cultures. The rickettsiae were concentrated and purified by passage through a sucrose gradient and inactivated with formalin. This vaccine satisfactorily passed preinactivation and final container testing and is believed to be superior to the presently available yolk sac vaccine.
落基山斑疹热疫苗是由在滚瓶培养的鸡胚细胞中生长的立克次氏体生产的。立克次氏体通过蔗糖梯度离心进行浓缩和纯化,并用福尔马林灭活。该疫苗顺利通过灭活前和最终容器检测,据信优于目前可用的卵黄囊疫苗。
