Definition for "oral vaccination"

Question

I want to write a definition for "oral vaccination" for a flashcard. I've come up with this:

The practice of swallowing a vaccine, also applied to animals by the use of baits, for example to prevent the spread of rabies among foxes.

Would that sound correct in form and content to a native speaker?

Answer 1

How about something simpler:

oral vaccination--the practice of administering vaccine by mouth (rather than by injection)
