To clarify...you are referring to the method of vaccine administration not the type of vaccine.

Live attenuated viruses create viral shedding, which creates a chance of passing the virus and are administered using oral drops.

Inactivated virus vaccines, do not create viral shedding, cannot pass off the virus, and are administered using an injection.

In general, attenuated viruses have the potential to create viral shedding and by extension pass on an infection. The fact that the live attenuated polio vaccine is done via drops is a secondary design decision for , gut immunity, shelf stability, ease of administration, etc. That it is oral drops itself does not cause the chance of passing on the virus.
