About this study
Official title: Pilot Introduction of the Modified Bivalent Killed Whole Cell Oral Cholera Vaccine in Orissa
The purpose of this study is to provide evidence for policymakers and key opinion leaders on the pilot implementation of cholera vaccination using the newly licensed Oral Cholera Vaccine (OCV) in India. The pilot introduction will provide the evidence for the feasibility, costs and population acceptance of large-scale cholera vaccination using the Indian vaccine (using vaccination coverage rates and other measures).
Read the detailed description
Severe diarrhoeal disease caused by Vibrio cholerae O1 and O139 has long been an important cause of mortality and morbidity in India. The availability and recent licensure of the modified bivalent killed whole cell OCV in India provides hope that the disease may be controlled in areas where the disease is a problem. On April 10, 2009, a meeting was organized by the Indian Council of Medical Research (ICMR), the Department of Biotechnology and the IVI. The recommendations from the meeting are as follows:
- As the modified WC vaccine is safe, effective, and cost-effective, it was suggested that the National Technical Advisory Group on Immunization (NTAGI) should consider recommending introduction of the vaccine in public health programs targeted to appropriate populations in India.
- Vaccination should be initiated in selected highly endemic and/or slum areas such as known areas in West Bengal or Orissa. The pilot vaccination programs will be monitored and evaluated. Further expansion to other areas and wider policy changes will be made in a step-by-step fashion based on the pilot programs. Logistical and operational issues need to be defined.
The aim of the study is to conduct a pilot introduction of the modified killed oral cholera vaccine in a public health setting in a population of ~50,000 before implementing in a larger scale.
Primary objective:
To determine the feasibility, acceptability and costs associated with pilot introduction of the modified killed whole cell oral cholera vaccine in India when given in a public health setting.
Secondary objective:
To identify challenges to mass oral cholera vaccine implementation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Consenting, eligible participants | All consenting eligible participants in the study area will receive the oral cholera vaccine |
What is being measured
The primary outcome is the main question the study is designed to answer.
To determine the feasibility
Feasibility will be determined by the vaccine coverage (%), defined as the number of subjects who received the vaccine doses divided by the number of subjects who are targeted for mass vaccination.
Measured: The numerator (number of people who received the vaccine doses within the target population) will be counted during the 30 days following the last dose of vaccination.
Secondary outcomes (1)
Assessment of acceptability and costs of vaccination program
Costs of vaccination program will be defined as the sum of the cost items required for social mobilization, mass vaccination, and post-vaccination actiities. This includes 1) vaccine price, 2) shipment and insurance costs, 3) personnel(FTEs), 4) supplies including coldboxes and vaccine carriers, 5) transportation.
Acceptability will be evaluated by
- vaccine coverage rate
- survey results which will be qualtitaviely and quantitatively summarized by the sociobehavioral scientists based on in-person interviews.
Measured: For a thirty days starting from the 30 days following the last dose of vaccination
