--------------------------------------
My impression: Newcastle disease LaSota vaccine and Newcastle disease strain IV vaccine should belong to the same type, just with different names, and are of medium virulence; while Clone 30 further attenuates the strain, making it a low-attenuated vaccine type. Let's discuss together.

Thanks to the friend above for the answer, please more friends come to answer questions

Strain IV vaccine is the LaSota strain, which is attenuated.
By cloning and attenuating this strain, you can obtain Clone 30; comparatively, 30 is slightly weaker than strain IV.
Clone 30 is superior to strain IV in breaking through maternal antibodies and in average antibody levels.
In fact, oil vaccines are also produced by inactivating the strain IV virus.
