Do vaccinations work against cholera?

The traditional injectable cholera vaccine conveys incomplete, unreliable protection of short duration and its use, therefore, is not recommended. However, two oral cholera vaccines that provide high level protection for several months against cholera caused by Vibrio cholerae 01 have recently become available in a few countries for use by travellers. For more information contact your health care provider or local office of public health. No country requires proof of cholera vaccination as a condition for entry and the International Certificate of Vaccination no longer provides a specific space for recording of cholera vaccination.
