Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, non-randomized study. Volunteers will be vaccinated with the oral cholera vaccine, Vaxchora. Vaxchora has been licensed by the Food and Drug Administration (FDA) for travelers to developing countries. Volunteers will also be asked to provide blood specimens over a follow-up time period of up to eight years. The specimens obtained in this clinical research study will be used to further the investigator's understanding of the protective immunological mechanisms that can be elicited systemically and may be applicable to other enteric pathogens.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vaccination with Oral Cholera Vaccine (Vaxchora)

Volunteers receive immunization with Vaxchora cholera vaccine. Blood draws are performed at subsequent visits.

Group Type EXPERIMENTAL

Vaxchora

Intervention Type DRUG

One dose. Approximately 100 mL of cold or room temperature purified bottled water is placed into a clean disposable cup. The contents of the buffer sachet are added to the water and stirred. Then the contents of the active (lyophilized vaccine) sachet are added to the water and stirred for approximately 30 seconds. The reconstituted mixture should be completely ingested within 15 minutes.
