What should you know about immunization for typhoid fever?

Typhoid fever is caused by Salmonella Typhi and spreads mainly through contaminated food or water. Vaccination prepares the immune system to respond to the bacteria, yet protection is not complete and it is not a treatment for an existing infection. A travel clinic or clinician can consider your destination, travel style, medical history and timing before recommending a vaccine. Protection may need a planned booster, depending on the vaccine used and your ongoing risk.

Arrange travel advice early enough to complete the recommended vaccine schedule. Drink sealed or suitably treated water, choose food that is thoroughly cooked and hot, and wash hands before eating. Keep the vaccination record with your travel documents. If you develop fever, diarrhoea, abdominal discomfort or marked tiredness during travel or after returning, contact a clinician and mention your travel history. Antibiotic Treatment may be used for confirmed illness, but antibiotics should not be self-started.

Seek medical advice promptly for a persistent or worsening fever after travel to a place where typhoid occurs, especially with diarrhoea, vomiting, abdominal pain, confusion or difficulty drinking. Urgent help is needed for severe dehydration, fainting, blood in stool, breathing difficulty or unusual drowsiness. Vaccination does not rule out typhoid or other infections, so symptoms need their own assessment.

Ask which vaccine suits your destination and departure date, whether another dose is needed for future travel, and whether illness or medicines affect the plan. Ask what water and food precautions fit your itinerary, and which symptoms should trigger testing or treatment.
