About GelVac(TM) and GelSite(R)

The GelVac(TM) system is a broad nasal powder vaccine delivery platform based on GelSite(R) polymer. The technology is seen as a potential rapid and cost-effective way to immunize large populations during outbreaks of biological warfare or pandemic disease, without the use of conventional needle delivery technology or caregiver assistance. It also eliminates the need for mercury preservatives and does not require cold storage.

GelSite(R) polymer is a naturally sourced, high molecular weight charged polysaccharide that exhibits distinct chemical and functional properties that are proprietary to the Company. GelSite is water-based and is capable of in situ gelation, i.e., changing from a liquid or a powder to a gel upon contact with body fluids. GelSite is not an adjuvant and is a member of a family of plant polysaccharides classified by the FDA as Generally Regarded As Safe (GRAS) and is manufactured under cGMP.
