What is Typhoid Fever?

Typhoid fever is a bacterial infection which spreads throughout the body affecting multiple organs. If untreated, typhoid fever can cause serious complications e.g. internal bleeding which can fatal.


Areas of high risk for typhoid fever include the Indian subcontinent, parts of Africa, south and southeast Asia and South America. If it is not immediately diagnosed and treated it can lead to permanent disabilities or death.

Where is the Typhoid Fever located?

Areas that are most affected with the typhoid fever are usually the ones where the standards of hygiene are low.  Areas of high risk for typhoid fever include the Indian subcontinent, parts of Africa, south and southeast Asia and South America. It has been shown that the people who develop the symptoms,s of the typhoid fever usually get it after having visited countries such as India, Pakistan or Bangladesh.

A vaccination for typhoid fever is recommended if you are travelling to an area of high risk, especially if you are planning on staying there for longer periods or if you intend on working with the locals. 

The Typhoid Fever Vaccine

There are two vaccinations available to choose from. One is an injection, the other consists of a course of tablets. Which vaccine is suitable for you depends on your age and medical history.

  • Vi vaccine (given in one dose as a single injection).
  • Ty21a vaccine (given in 3 doses as capsules taken on alternate days).

The vaccine prompts your body to produce antibodies which in turn help your immune system to battle the typhoid bacteria. Extra precautions should be taken as the vaccine is not 100% effective, so being cautious about the food and water abroad is recommended. 

Who should not have the Typhoid Vaccine?

The Ty21a is not suitable for people with a compromised immune system e.g. a diagnosis of HIV or if receiving treatment for another disease. There is no evidence to suggest either vaccination is unsafe for pregnant or breastfeeding women. The Typhoid vaccine is not recommended for children under 6 years of age.
