They worked well for me, not eliminating my allergic response but significantly reducing it for about a decade after 2-3 years of shots. Note that the same treatment can be given via drops, a much less expensive option (but still considered off label use in the US). I haven't tried them (yet) but it seems like the research performed so far shows them to be just as effective (I'd guess also just as ineffective if the shots don't work for you).
