The August 2000 issue of the journal Infection and Immunity published findings that seem promising for an experimental oral vaccine against pathogenic Escherichia coli. Currently being tested on Israeli military volunteers, the vaccine appears to be safe and to stimulate an appropriate immune response. The study was conducted by researchers from the Israeli Defense Force; Tel Aviv University; Technion-Israel Institute of Technology; University of Negrev; Hebrew University and Hassadah Medical School, Jerusalem; the Walter Reed Army Institute of Research, Washington, DC; and the University of Goteborg, Sweden.
