6 months may not have been long enough for them to work. And allergy shot protocols are not standardized. Your allergist may not have used a large enough dose or the right updosing schedule. I've had shots at three different allergists (I stopped the first two treatments for personal reasons unrelated to the treatment), and this third one seems to give larger doses (which unfortunately makes the shots more painful), and is also the most effective one by far.
