Typhoid vaccine is used to prevent typhoid fever. Typhoid fever is caused by the bacterium Salmonella typhi (S. typhi). Typhoid is spread by contaminated water and food. The typhoid vaccine contains a small amount of the typhoid bacteria, enough to stimulate your body to create its own defenses but not enough to cause serious illness. It takes about 2 weeks after injection for the vaccine to begin protecting against typhoid fever.
The typhoid vaccine is recommended for adults and children at least 2 years of age who will be travelling to areas where there is a risk of exposure to S. typhi. In particular, people who will be exposed to potentially contaminated food and water for longer periods of time (more than 4 weeks) should consider receiving this vaccination. It is also recommended for travellers who have reduced or no gastric (stomach) acid secretion, those who live with or have regular contact with someone known to carry S. typhi, and laboratory workers who routinely handle specimens that contain or are believed to contain S. typhi.
The vaccine reduces but does not eliminate the chances of a person getting typhoid fever. Travelers should take all necessary precautions to avoid potentially contaminated sources of food or water. Such precautions include drinking bottled or boiled water and washing hands before eating.

A repeat vaccination (“booster”) is recommended every 3 years if you repeatedly travel to areas where you are exposed to S. typhi.
