When Is Typhoid Vaccination Recommended for Typhoid Fever?

A clinician may discuss vaccination if you are travelling to an area where typhoid is more common, visiting family, staying for a prolonged period, or expecting close contact with local communities. It may also be considered for people with occupational exposure to Salmonella Typhi. The vaccine lowers risk but does not replace careful food and water hygiene.

Vaccination needs planning because protection is not immediate and the choice of vaccine depends on age, health, travel plans, and previous doses. Tell the clinician about pregnancy, immune problems, allergies, and medicines. A person who already has fever, abdominal discomfort, diarrhoea, constipation, or marked weakness needs medical assessment; vaccination does not clear bacteria from the body.

Arrange a travel-health consultation well before departure so there is time to review the schedule and complete any recommended dose. Continue drinking treated or sealed water, eat food that is thoroughly cooked and served hot, and wash hands after using the toilet and before eating. Keep a record of previous vaccinations and explain the countries and type of accommodation involved.

If typhoid fever is suspected after travel, seek clinical advice rather than relying on a vaccine. Testing and prescribed antibiotics may be needed, and close contacts should follow hygiene advice.

Seek prompt medical care for persistent fever after travel, worsening weakness, confusion, severe abdominal pain, repeated vomiting, blood in the stool, or signs of dehydration such as very little urine and dizziness. A high fever with a recent stay in an area where typhoid occurs warrants assessment even if vaccination was given.

Ask which vaccine suits your age and health, when it should be given before travel, what side effects to watch for, and which food and water precautions remain necessary.
