The CDC estimates that 20 to 50 percent of internationaltravelers contract diarrhea. Of greater concern is the effects can progressbeyond acute symptoms. Between 10 and 30 percent of those who developtravelers' diarrhea will develop the chronic symptoms of irritable bowelsyndrome.
Intercell will also gain full rights to two additionalclinical and three preclinical programs under development, the most advancedbeing an immunostimulant vaccine patch in Phase II for pandemic influenza.
