Allergy vaccination is traditionally administered as subcutaneous injections or sublingual droplets. ALK-Abell’s aims to extend the use of allergy vaccination by introducing convenient, tablet-based vaccines, thereby offering many more patients a causal allergy treatment. Allergy-desensitization shots (immunotherapy) may help if your child has allergic asthma that can’t be easily controlled by avoiding asthma triggers or with asthma medication. Your child’s doctor will start with skin tests to determine which allergens trigger the asthma symptoms in children.
