Like some vaccines (4)

Ross

I believe the answer is:

oral

'like some vaccines' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for oral that I've seen before include "Concerning the mouth" , "Viva voce" , "Ant; tourist (dial.)" , "See 18" , "language exam" .)

I've seen this clue in The Wall Street Journal, The New York Times and the King Feature Syndicate.
