Updated Friday, September 21, 2007 0:00 am TWN, AFP CHICAGO -- Scientists at a major disease conference Wednesday announced a skin-patch vaccine that can save the wearer from the rumblings of diarrhea when traveling to places where stomach bugs are endemic. A clinical trial by Maryland-based vaccine maker Iomai Corporation showed that of 59 people who used the patch — which slaps on the skin to deliver the vaccine without a needle — only three found their guts growling with diarrhea.
