Protect Yourself Against Cholera with Vaccination

Cholera is a severe diarrheal disease caused by the Vibrio cholerae bacteria, typically spread through contaminated water and food. Vaccination is a crucial measure for prevention, especially for those traveling to or living in high-risk areas.

What is Cholera?

Cholera causes acute watery diarrhea and vomiting, leading to severe dehydration. Without prompt treatment, it can be life-threatening. It is prevalent in areas with poor sanitation and limited access to clean water.

Types of Cholera Vaccines

In Singapore, there are two primary types of cholera vaccines approved by the World Health Organization (WHO):

• Dukoral: A drinkable vaccine that provides protection against cholera and has an additional benefit against traveler’s diarrhea caused by ETEC (enterotoxigenic Escherichia coli).
• Euvichol-Plus: An oral vaccine offering protection against cholera, particularly in outbreak situations.

These vaccines are generally administered in two doses, with the second dose taken 1-6 weeks after the first.

Who Should Get Vaccinated?

Cholera vaccination is recommended for:

• Travelers to cholera-endemic regions
• Residents in areas with ongoing cholera outbreaks
• Individuals in humanitarian crisis settings with high cholera risk

Vaccination Schedule and Effectiveness

The cholera vaccine is most effective when taken at least 10 days before potential exposure. It provides significant protection for up to 2 years with Dukoral and at least 3 years with Euvichol-Plus after completing the two-dose series.
