World's first honeybee vaccine

A Ph.D. acquaintance of mine who's work specializes in honeybees has said there's contention in her field at calling this a "vaccine", saying that such work on bee vaccines has been done before this new one (she was involved in the prior's research) but that approval was denied in part for its referral as a "vaccine". 

The issue was that vaccine as a term implies production of an immunogenic response in the form of antibodies, and as insects lack those then it didn't fit the bill, so... rejection. She's kinda fuming right now that suddenly that seems to have been ignored and this new one gets the label of "vaccine".

A problem of academic semantics lol
