Well, that would be true supposing that Neville's granny is aware 
of the prophecy. Not just that the prophecy exists but that also 
it's contents. And that Neville could be targeted.

So far, there has been no clear indication in the books that 
anyone apart from Dumbledore and now, Harry knows the prophecy. 
Yeah, it is true that it looked like the members of the Order of 
Phoenix know that there is a prophecy as do the Death Eaters but I 
wonder how many people know it in it's entriety?

Also if, the Order knows that Voldemort is after Harry because he 
is supposed to kill Voldemort, then how can they be ever so 
complacent about keeping Harry in the dark?
