How do allergy vaccinations work?

Question

I've been recently diagnosed with having a whole consortium of items that produce an allergic reaction within me, mainly airborne items. I was informed that by taking a series of vaccinations, I could be desensitized to these allergens, thereby being able to breath some what normally. I was also informed that the shots are comprised of the allergens themselves, and that by introducing these into the body at regular intervals, the body eventually becomes immune to the allergens' affects. Yet I'm still curious. If this method works for vaccinations, why doesn't constant daily exposer to airborne allergens produce the same immunity?

Answer 1

Hi there. I believe that because you get a very low dose of the allergen, you don't get a big allergic reaction. The histamine in your blood that causes you to react so badly (histamine being the substance that your body makes to "fight" the allergen) , gets the most of it in case of an airborne allergen, and that does not allow your body to get used to the substance in a normal way. So, to make your body used to the substance, you get small doses of it and this will make the allergic reactions less bad :)

Chameleon had a very good answer. However, I can speak from personal experience. Allergy desensitation shots really do help, but you must be resigned to taking them long-term. It took two years for the shots to start helping me. It was 5 years before they did me a lot of good. I had a series of shots that lasted 9 years. I stopped the shots 5 years ago and I still have the benefits. I was allergic to almost all pollens, some molds and dust mites. I used to be allergic to nearly all raw fruits and vegetables, now I can eat them with no problem. I had what is called, "oral allergy syndrome". The shots made it go away.

The vaccinations cannot stop your body from reacting to the allergen, but what they do is, they change the way it reacts to them. Here, the key is the dose of the allergen.

Your shots will start at a very low dose and gradually increase. When exposed to allergens at low doses, your body produces IgG's that recognise and destroy the allergens in a relatively peaceful way (no swellings, rush..)..

But when exposed to allergens at a high dose (at naturally they are always too high), your body responds with IgE's, which cause a severe immune reaction. Perhaps at higher doses they are recognised as a threat to your health..

The point of the therapy is to make you produce more IgGs rather than IgE's. The dose of the allergens are increased, gradually reaching high levels as you start to produce more IgG's. Therefore in the future your body learns to respond to allergens with IgGs, in a peaceful way..

so make sure to avoid allergens in general, until your shots are complete..

i'm getting hypersensitive reaction vaccinations too. They do artwork yet take a protracted time to end. ( years in line with hazard ) they do no longer thoroughly do away with the allergic reactions, they only make him much less tormented by them

Answer 5

they slowly make your body ammune to them
