Introduction
Typhoid fever is a serious illness caused by the bacterium Salmonella Typhi, which can be contracted through contaminated food and water. For travellers, especially those visiting areas where typhoid is prevalent, vaccination is a vital step in ensuring health and safety. At Edinburgh Travel Clinic, we understand the importance of vaccinations and are here to provide you with the information you need about the typhoid vaccine, including how long it remains effective.
Understanding the Typhoid Vaccine
Types of Typhoid Vaccines
There are two main types of typhoid vaccines available: the inactivated (killed) vaccine and the live attenuated vaccine. The inactivated vaccine is administered as an injection, while the live attenuated vaccine is given orally. Both vaccines are effective in preventing typhoid fever, but they differ in their administration and duration of immunity.
Duration of Immunity
The duration of immunity provided by the typhoid vaccine varies depending on the type of vaccine received. The inactivated vaccine typically provides protection for about two years, while the oral live attenuated vaccine offers immunity for approximately five years. It is essential for travellers to be aware of these timelines to ensure they are adequately protected before embarking on their journeys.
Importance of Vaccination for Travellers
Risks of Typhoid Fever
Typhoid fever is endemic in many developing countries, particularly in South Asia, Africa, and parts of Central and South America. Travellers from Edinburgh should be aware of the risks associated with consuming contaminated food and water in these regions. Vaccination significantly reduces the risk of contracting the disease, making it a crucial consideration for anyone planning to travel.
Recommendations for Travellers
Health authorities, including the NHS, recommend that travellers to high-risk areas receive the typhoid vaccine at least two weeks before departure. This allows sufficient time for the body to build immunity. At Edinburgh Travel Clinic, we advise our clients to consider their travel itinerary and potential exposure to contaminated sources when determining the timing of their vaccination.
When to Get Revaccinated
Revaccination Guidelines
For those who have received the inactivated typhoid vaccine, it is recommended to get revaccinated every two years if you continue to travel to areas where typhoid fever is common. For those who have had the oral vaccine, a booster dose is advised every five years. Keeping track of your vaccination status is essential for maintaining protection against typhoid fever.

Additional Health Considerations
Hygiene Practices
While vaccination is a critical step in preventing typhoid fever, practising good hygiene is equally important. Travellers should always wash their hands thoroughly with soap and water, especially before eating or preparing food. Drinking bottled or boiled water and avoiding raw or undercooked foods can further reduce the risk of infection.
Monitoring Symptoms
It is also crucial for travellers to be aware of the symptoms of typhoid fever, which can include prolonged fever, fatigue, headache, nausea, and abdominal pain. If you experience any of these symptoms after returning from a high-risk area, seek medical attention promptly. At Edinburgh Travel Clinic, we can provide guidance on what to do if you suspect you have contracted typhoid fever.
Conclusion
Understanding how long the typhoid vaccine is effective is essential for anyone planning to travel, especially from Edinburgh to regions where typhoid fever is prevalent. The inactivated vaccine offers protection for about two years, while the oral vaccine provides immunity for up to five years. Staying informed about your vaccination status and adhering to recommended guidelines can help ensure a safe and healthy travel experience.
