Abstract

BACKGROUND: Typhoid fever caused by Salmonella enteric serovar Typhi (S. Typhi) is a common cause of morbidity in the world. In 2017, 14.3 million cases of Typhoid and paratyphoid fever occurred globally. School age children between 3 to 19 years old are the most affected. Poor sanitation and multi drug resistance have increased the need for vaccines to reduce the global burden of disease. Based on previous trials, typhoid conjugate vaccines have longer- lasting protection, higher efficacy, require fewer doses and are suitable from infancy that allows them to be incorporated into the routine immunization program. Our previous phase I trial proved that a novel Vi-DT typhoid conjugate vaccine is safe and immunogenic in subjects 2-5 and 18-40 years. Our phase II trial consisted of subjects 6 months to 40 years. Our previously published paper on subjects 6 to /=4 times. The Vi-DT group produced a higher GMT as compared to Vi-PS. CONCLUSION: Vi-DT vaccine is safe and immunogenic in children 2-11 years old. TRIAL REGISTRATION: Trial registration number: NCT03460405 .
