Allergies can be treated with immunotherapy.
I focused on allergy to birch pollen, but most of my findings should be true for other pollen allergies as well. It seems that immunotherapy is a good way to treat pollen allergy. There are some studies that show that it's a very effective treatment  and other, that show that the benefit is small . In both cases though the benefit is visible in comparison with placebo group. Sublingual immunotherapy (SLIT) is considered safer and giving less adverse effects than Subcutaneous immunotherapy (SCIT), but some studies  reported serious adverse effects even in group treated with SLIT. Patients didn't get anaphylaxis, but they had to get a shot of epinephrine. That happened to 9 patients in SLIT group (per 159 people in the group), and only to 3 patients in placebo group.
