How Do Allergy Shots Work?
Vaccines and allergy shots work similarly, where a small amount of allergen is given in increasing doses to a patient in order for them to build immunity to the allergen. This can take time and maintenance for the patient, so the allergy should be a long-lasting one that affects your life regularly enough that you are seeking therapy. The first phase of allergy immunotherapy ranges from three to six months, and the maintenance phase can be decided by your allergist once you receive initial allergy shots.
