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 is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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)
  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

    1. vaccine coverage rate
    2. 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

Questions about this trial

What is this clinical trial studying?

An observational study of Cholera, run by International Vaccine Institute at 1 site in India.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 May 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine the feasibility (time frame: 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.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2013.
