Typhoid vaccination protects against a bacterial infection caused by contaminated food or water, common in regions with poor sanitation. It is recommended for travellers to South Asia, parts of Africa, and Central and South America. A pre-travel consultation reviews your itinerary to confirm whether typhoid vaccination is advised.
What Is Typhoid?
Typhoid fever is a bacterial infection caused by Salmonella Typhi, spread through contaminated food or water. It causes prolonged fever, headache, abdominal pain and, in severe cases, serious complications requiring hospital treatment. Typhoid is most common in areas with limited access to clean water and sanitation.
Who Should Consider Vaccination?
Vaccination is generally recommended for travellers visiting South Asia, sub-Saharan Africa, and parts of Central and South America, particularly those staying with local communities, backpacking, or visiting areas with limited sanitation infrastructure. It may also be considered for shorter trips depending on planned activities and food and water precautions.
Vaccination Schedule
A single injectable dose typically provides protection and is usually given at least two weeks before travel to allow immunity to develop. Boosters may be recommended every three years for travellers with ongoing exposure risk. An oral vaccine alternative is also available in some cases.
Food and Water Precautions
Vaccination reduces but does not eliminate the risk of typhoid. Following safe food and water practices, such as drinking bottled or treated water and avoiding uncooked food from unreliable sources, remains important even after vaccination.
Frequently Asked Questions
How long before travel should I have the typhoid vaccine?
Ideally at least two weeks before departure, to allow the vaccine time to provide effective protection.
How long does typhoid vaccine protection last?
The injectable vaccine typically provides protection for around three years, after which a booster may be recommended for ongoing exposure risk.
Is typhoid vaccination available on the NHS?
Typhoid vaccination may be available free through the NHS depending on your circumstances, or privately through a travel clinic. Your clinician will confirm eligibility during consultation.
Can typhoid vaccine be given with other travel vaccines?
Yes, it can usually be given alongside other travel vaccines at the same appointment, subject to clinical assessment.
Does the vaccine mean I no longer need to be careful with food and water?
No, vaccination reduces but does not eliminate risk. Safe food and water practices remain important even after vaccination.
