The purpose of this study is to evaluate the safety of an investigational vaccine intended to treat allergy to Japanese red cedar. The vaccine is composed of DNA, which is the material that cells use to provide instructions to make proteins. The DNA carries the information necessary to make a special protein which is a combination of a protein found in all cells, LAMP (lysosomal associated membrane protein), and the protein from Japanese red cedar that causes the allergy known as Cry J2. This vaccine is intended to help re-educate the immune system with respect to how it will respond to naturally occurring red cedar allergen and eliminate the allergic symptoms. Another purpose of this study will be to document the immune response to the vaccine
