Patients who took a new vaccine against traveller's diarrhea were significantly less likely to experience the uncomfortable ailment than those who were given a placebo, a new study has found.

The study on the effects of the patch-based vaccine was published in The Lancet medical journal this week...

Although the evidence provided in the report clearly outlined the benefits of the Iomai patch, there were several aspects this treatment that went unmentioned.

Treatment cost and availability were not discussed and potential adverse reactions to the patch vaccine were not addressed. While the article did indicate that there were "no-vaccine related side effects," one might wonder how the researchers were able to distinguish potential vaccine side effects from symptoms of traveler's diarrhea itself?

In addition to including the information source details, it may have also been helpful to outline alternative ways to minimize the risk of traveler's diarrhea and/or treat the symptoms of this disease (i.e. hand washing, careful food selection, peptobismol or alternative antibiotics).
