At Eltham Pharmacy in London, we understand that safeguarding your health is a top priority when travelling to regions with a risk of cholera. Cholera is an infectious disease that can cause severe diarrhoea and dehydration, primarily spread through contaminated food and water. For UK travellers heading to high-risk destinations, the cholera vaccine can offer essential protection. In this guide, we’ll explore the effectiveness of the cholera vaccine, how it works, and what you can expect in terms of coverage, helping you make an informed decision about your health.
What is Cholera?
Cholera is caused by the bacterium Vibrio cholerae, which is typically found in water or food sources contaminated by faecal matter. While it’s relatively rare in the UK, cholera remains a risk in parts of Africa, Asia, and the Caribbean, particularly in regions with poor sanitation. Cholera can cause severe dehydration and, if left untreated, can be fatal, especially in vulnerable populations.
UK travellers visiting areas with limited access to clean water and sanitation should consider taking preventive measures, including vaccination, to reduce the risk of contracting cholera.
How Effective is the Cholera Vaccine?
The cholera vaccine available in the UK, known as Dukoral, is an oral vaccine that provides effective protection against cholera for most travellers. Studies show that Dukoral offers approximately 85-90% protection for the first six months following vaccination and around 60% effectiveness up to two years after the initial dose. The effectiveness may vary depending on individual health factors, environmental exposure, and adherence to food and water precautions while travelling.
While the cholera vaccine is highly effective, it’s important to understand that no vaccine offers 100% protection. Combining the vaccine with safe food and water practices can significantly reduce the risk of contracting cholera.
How Does the Cholera Vaccine Work?
Dukoral works by stimulating an immune response in the body to the cholera bacteria. The vaccine contains inactivated Vibrio cholerae bacteria and a small amount of a toxin component, which is harmless but helps the body recognise and respond to cholera infection. By introducing these elements, the vaccine enables your immune system to develop defences against cholera, reducing the likelihood of infection if exposed to the bacteria.
You take Dukoral orally in two doses, with the second dose following one to six weeks after the first. We recommend completing both doses at least one week before travelling to ensure adequate protection.
Who Should Consider the Cholera Vaccine?
In the UK, the cholera vaccine is not routinely given as it’s primarily intended for travellers heading to regions with a high risk of cholera transmission. The World Health Organization (WHO) recommends the vaccine for those at higher risk, including:
Travellers visiting cholera-endemic regions: This includes parts of Africa, Southeast Asia, India, and certain areas of the Caribbean and Central America, particularly where clean water is scarce.
Those engaging in humanitarian aid work or disaster relief efforts: If travelling to areas recently affected by natural disasters or lacking basic sanitation, the vaccine can provide added protection.
Individuals visiting friends or family in high-risk areas: Travellers staying in local settings with limited sanitation are at increased risk compared to those in tourist accommodations.
If you’re uncertain about whether you need the cholera vaccine, our travel clinic team at Eltham Pharmacy can advise based on your specific travel plans.
What to Expect in Terms of Protection
The cholera vaccine protects against severe symptoms and reduces the risk of infection, especially when paired with safe food and water practices. However, it’s crucial to remember that the vaccine does not provide complete immunity. To further reduce your risk of cholera, follow these food and water safety tips:
Drink only bottled or boiled water: Avoid tap water, ice, and beverages made with unboiled water.
Avoid raw foods: Choose freshly cooked meals, especially meats, seafood, and vegetables, to reduce exposure to bacteria.
Practise good hygiene: Wash hands frequently with soap and water, especially before eating and after using the bathroom.
Combining the cholera vaccine with these practices offers a robust defence, significantly lowering your chances of contracting cholera.
Are There Side Effects of the Cholera Vaccine?
Dukoral is generally well-tolerated, and side effects are rare. Some individuals may experience mild stomach discomfort, nausea, or headache, which typically resolves within a day or two. Serious side effects are extremely rare, making Dukoral a safe option for most travellers. If you have specific health conditions or concerns, our team at Eltham Pharmacy can discuss whether the vaccine is appropriate for you.
How Long Does the Cholera Vaccine Last?
The cholera vaccine provides short-term protection, effective for around two years after the initial doses. If you plan on travelling to high-risk areas frequently, you should get a booster dose every two years to maintain immunity. For children aged 2-6, the vaccine only lasts for six months, so they should receive a booster if they remain at risk.
