Diarrhoea vaccine in a patch
Travellers’ diarrhoea — often caused by enterotoxigenic Escherichia coli — could be prevented by pre-vaccination with a patch containing heat-labile toxins from E coli, a Lancet study suggests ().
Although the 170-patient study was not powered to test efficacy of this strategy, the researchers report that patients given the vaccine patch were less likely to have moderate-to-severe diarrhoea (P=0.0070) or severe diarrhoea (P=0.0332) than those given sham patches.
