About Oral Cholera Vaccine
Indications of Oral Cholera Vaccine
Approved Use
Oral Cholera Vaccine is indicated for active immunization against cholera caused by Vibrio cholerae serogroup O1 (and, for bivalent formulations, serogroup O139) in individuals living in or travelling to cholera-endemic or epidemic areas.
- Established/guideline-supported use: Primary prevention of cholera in residents of cholera-endemic regions, including as part of WHO-coordinated mass vaccination campaigns during outbreaks or humanitarian emergencies (e.g. displacement camps, flood- or conflict-affected areas with high cholera risk).
- Established use: Pre-travel prophylaxis for adults and children travelling to areas with active cholera transmission, particularly humanitarian workers, healthcare workers, and travelers to remote endemic regions with limited access to safe water and medical care.
- Adjunct role: Oral Cholera Vaccine is an adjunct to, and does not replace, standard cholera-prevention measures such as safe drinking water, food hygiene, sanitation, and handwashing, which must be continued regardless of vaccination status.
Oral Cholera Vaccine does not protect against illness caused by organisms other than Vibrio cholerae and is not indicated for treatment of active cholera infection.
Dosage & Administration of Oral Cholera Vaccine
Dosage by Indication
| Population | Primary Series | Interval Between Doses | Booster |
|---|---|---|---|
| Adults and children ≥ 1 year (endemic exposure/outbreak setting) | 2 oral doses | Usually 14 days apart (acceptable range approximately 7 days to 6 weeks per local guidance) | Repeat dose recommended after 2 years for individuals with continued high-risk exposure, per current guidelines |
| Adult travelers (single-dose live-attenuated formulations, where available) | 1 oral dose | Not applicable | Data on repeat dosing limited; consult current product labeling |
| Children 1 to < 2 years | 2 oral doses (may require dilution with additional water/buffer per formulation) | 14 days apart | As per adult schedule where established |
The complete multi-dose primary series of Oral Cholera Vaccine must be finished for optimal protection; a single dose of a two-dose regimen provides only partial, short-term protection.
Side Effects of Oral Cholera Vaccine
Most reported reactions to Oral Cholera Vaccine are mild and self-limited.
- Common: Abdominal pain, diarrhea, nausea, and loose stools following administration.

Contraindications of Oral Cholera Vaccine
- Known hypersensitivity (including severe allergic reaction) to any component of Oral Cholera Vaccine or to a previous dose of Oral Cholera Vaccine.
- Acute severe febrile illness or acute gastrointestinal illness at the time of scheduled dosing - vaccination should be deferred until recovery (this is a temporary deferral, not a permanent contraindication).
Frequently Asked Questions about Oral Cholera Vaccine
What is Oral Cholera Vaccine used for?
Oral Cholera Vaccine is used to help prevent cholera, a diarrheal illness caused by Vibrio cholerae, in people living in or traveling to areas where cholera occurs, and during outbreak vaccination campaigns.
How many doses of Oral Cholera Vaccine do I need?
Most formulations of Oral Cholera Vaccine require 2 doses taken about 14 days apart for full protection. It is important to complete both doses, as a single dose gives only partial, short-term protection.
