Narrative:

Small aircraft X being radar vectored for runway 16R ILS at vny. Approach controller stated 'TA 12 O'clock, 1/2 mi opposite direction, same altitude.' we turned sharply to the right but never saw the other aircraft. About 10 seconds later approach said traffic no factor. I don't know why the controller didn't notice the other traffic or give us a warning when it was further away than just 1/2 mi!
