RESUMO
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.
