Do vaccines confer protection?

The injectable cholera vaccine, previously used, conveyed incomplete, unreliable protection of short duration and is no longer recommended. Two new oral cholera vaccines which provide good protection for up to 3 years are now available for use by travellers. However, as these vaccines do not provide 100% protection, basic hygienic precautions should always be followed. For more information, contact your local travel medicine centre. No country requires proof of cholera vaccination as a condition for entry, and the international certificate of vaccination no longer provides a space for recording cholera vaccination.
