The vaccine, tested on children, not only prevented infection in those who received it, but also those who came in close contact with the affected, a new study said. The experiments may support World Health Organisation's efforts to eradicate typhoid, a deadly disease in tropical countries. Conducted by Seoul based International Vaccine Institute (IVI) in collaboration with the National Institute of Cholera and Enteric Diseases (NICED)of Kolkata, the study was published in today's issue of New England Journal of Medicine (NEJM). It says that typhoid fever is a major cause of illness and death in the developing world, killing an estimated 216,000 to 600,000 people annually.
