Singapore: Researchers at the University of Cambridge, UK, are developing a vaccine that would prevent bad stomach (or Delhi Belly as it is popularly called) or typhoid in tourists during vacations. The vaccine is to be taken in the form of powder and targets the E. Coli and salmonella bacteria.
The stomach ailment, 'Delhi belly' is said to affect about 10 million travellers per year and up to half of all tourists suffer from it in the form of cramps, diahorrea and dehydration. Researchers pointed out that the stomach virus is most commonly contracted by tourists in tropical country such as India.
Professor Nigel Slater, lead scientist, Department of Biochemical Engineering and Biotechnology, University of Cambridge, UK, said that, "The vaccine we have produced is a powder so it is very stable and does not need to be kept in cold storage. Clinical trials for the vaccine are due to begin later this year."
