NCT02727855

Brief Summary

To evaluate the preventive impact, demand, acceptability, uptake, feasibility, and cost-effectiveness of a two-dose regimen of the OCV Shanchol in children living in urban slums in Bangladesh, Investigators will conduct a targeted mass immunization programme, using an innovative approach successfully deployed by the Bangladesh government in its recent countrywide campaign of MR vaccination of 52 million children aged 9 months to 14 years (\<15 years). Investigators will undertake a census of a geographic population of approximately 300,000 persons, with GIS locations of each household. This census will be updated every 6 months during the follow-up period to permit tracking of births, deaths, and migrations, including changes in location of each individual's residence. Following the initial census, the OCV will be offered to all non-pregnant individuals aged 1 to 14 years. Operational research and economic studies will evaluate the coverage, feasibility, acceptability, demand, costs and cost-effectiveness of this vaccination programme.
