Diarrhoeal diseases are the most common illnesses in the world today, with an estimated 1.7B cases annually. Affecting 30-50% of travellers visiting developing countries, this is typically considered a non-life-threatening inconvenience, but diarrhoeal diseases kill over 2000 children every day in low- and middle- income countries. Vaccines have been successfully developed for diarrhoeal disease caused by cholera, typhoid and rotavirus. Shigella and Enterotoxigenic E. coli (ETEC) accounts for up to 50% of all diarrhoea cases, but no effective vaccines exist. In response to this, Eveliqure has developed ShigETEC, the only vaccine close to clinical testing that targets both these major bacterial pathogens.
