How do "allergy shots" treat asthma?

One of the things that doctors will suggest is using immunotherapy. Immunotherapy is the medical term for allergy shots - immuno meaning affecting the immune system and therapy is a form of treatment. What allergy shots do is prevent the allergic reaction from occurring. It causes the production of blocking antibodies and decreases the sensitivity of the cells. As a result, it allows patients to be able to breathe normally even when there is pollen, dander, dust or dust mites in the air. In many cases allergy shots have been so successful that many asthma patients are able to decrease their medications in terms of the amount and the frequency of the medication and can go through spring or fall without having an asthma attack.
