Typhoid fever is a highly contagious and potentially lethal disease, which spreads via contaminated foods and water. As typhoid bacteria are primarily found in faeces, the infection is particularly common in regions with poor sanitation.

· When to get vaccinated: At least two weeks before travel. It can also be given closer to you travel date but this leaves you at a greater risk of contracting the disease.

· How it is given: There are two different typhoid vaccines. 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.

· Course: One dose if you receive the typhoid injection. The oral vaccine consists of three capsules taken over a course of five days.

· Boosters: The typhoid vaccine protects you for three years. After that, you will need a booster if you travel to a risk area.
