There are more rabies vaccine strains, such as the Pasteur strain, Flury strain, SAD strain, GTN strain, and so on. The Pasteur strain is an ancient rabies vaccine strain, and there are various derivative strains of this strain. The Pasteur strain and its derivative strains have been used in a large number of rabies vaccine preparations for both humans and animals. The Flury strain is produced by passaging attenuated culture in chicken embryo cells and there are also some derivative strains.The SAD strain is currently used mainly for immunization of dogs and other animals.The GTN strain is produced by passaging culture in mouse brain and in human embryo lung diploid cells.The SAD strain is also used for immunization of dogs and other animals. Currently there is no significant difference in the immunization effect of rabies vaccines produced by different strains, and effective immunization can generally be achieved.
