Allergy Therapeutics, the makers of ragweed allergy vaccine Pollinex-R, are making headway with a new version of ragweed allergy vaccine called Pollinex Quattro Ragweed. This new formulation is an ultra-short course vaccine requiring only four shots in three weeks. The trials are on its last stages, and might take just a couple more years.

With additional late stage studies also planned in the treatment of Tree allergies, Pollinex Quattro is entering the final stages of the largest ever allergy vaccine development programme and the first conducted on a global basis. The Company expects to launch the first ever approved allergy vaccine in the United States in 2009.

Let's cross our fingers that this develops into another treatment option for people with pollen allergies.
