Cholera Vaccine

What is Cholera?

Cholera is a bacterial infection that can have severe consequences if left untreated. It causes intense diarrhoea, leading to dehydration, and can be fatal in some cases. The infection is typically contracted by consuming contaminated food or drink. However, with the right precautions and timely vaccination, the risks can be significantly reduced.

What are the symptoms of Cholera?

After exposure to the cholera bacteria, the incubation period can last anywhere from 12 hours up to 5 days. It’s important to be aware of the potential symptoms:

• Around 75% of individuals infected with cholera will experience mild symptoms.
• Individuals with underlying health issues are more susceptible to developing severe illnesses.
• In severe cases, rapid onset of diarrhoea and vomiting can lead to extreme dehydration, which requires immediate medical attention to avoid life-threatening complications.

High-Risk Areas

Cholera outbreaks are typically found in regions with poor sanitation systems. Additionally, areas affected by war or natural disasters are at higher risk of experiencing cholera epidemics. Countries such as Kenya, Nigeria, Malawi, Democratic Republic of Congo, Afghanistan, and Iraq have witnessed cholera outbreaks in the past. However, it’s crucial to stay informed about current conditions in specific locations before travelling.

Preventative Measures

When travelling to high-risk areas, there are several important steps you can take to minimise the chances of contracting cholera:

1. Practise good hygiene: Always wash your hands thoroughly with soap, especially before preparing food or beverages.
2. Avoid tap water: Refrain from drinking water from unknown sources. It’s safer to rely on bottled or boiled water for consumption.
3. Dental hygiene: Brush your teeth using boiled or bottled water to avoid any potential contamination.
4. Proper food preparation: Exercise caution with uncooked vegetables. Ensure they are thoroughly washed and prepared before consumption.
5. Ice and seafood: Avoid consuming ice in your drinks and be cautious when consuming seafood or shellfish.

The Cholera Vaccine

At Travel Vaccine Clinic, we offer the cholera vaccine as an effective preventive measure against the infection. The vaccine is administered orally in the form of a drink. Adults typically require two doses, which should be taken 7 days apart. After completing the vaccine course, adults are protected for two years. Children may require additional boosters, with up to 3 boosters recommended for optimal protection.

To ensure the vaccine’s efficacy, it’s essential to follow certain guidelines. Prior to your vaccine appointment, avoid eating or drinking for at least one hour before and after the appointment. This will help maximise the vaccine’s absorption and effectiveness.

Cholera Side Effects

While the cholera vaccine is generally safe, there are certain considerations to keep in mind:

• Children under two years old should not receive the vaccine.
• Side effects are rare, but some individuals may experience headaches, fever, or digestive problems. These symptoms typically occur in approximately one in 100 patients and severe reactions remain extremely rare.

How Long Does the Cholera Vaccine Last?

The vaccination is administered orally. Adults should receive two doses, spaced 1 to 6 weeks apart, to ensure protection for up to 2 years. Both doses must be completed at least one week prior to travel.
