Does typhoid vaccination treat typhoid fever?

A vaccine prepares the immune system to respond to typhoid bacteria before exposure. It is a preventive measure, not a medicine that clears bacteria from someone who is already ill. Protection is not complete, so safe food and water habits remain important. Typhoid fever may cause prolonged fever, headache, weakness, stomach symptoms, or changes in bowel habits. Several illnesses can look similar, and a clinician decides whether tests and antibiotics are needed.

Contact a healthcare professional promptly if you have a persistent fever with marked tiredness or digestive symptoms, particularly after travel or unsafe food or water exposure. Mention any recent vaccination, travel, medicines, and antibiotic use. Drink safe fluids and avoid sharing food or preparing meals for others until you have received advice. Take prescribed treatment exactly as directed and do not rely on a vaccine dose to treat current symptoms.

Seek urgent care if fever is accompanied by confusion, fainting, severe dehydration, repeated vomiting, severe abdominal pain, blood in the stool, or unusual drowsiness. A person who cannot drink or is passing very little urine needs prompt attention. Keep children and vulnerable adults under closer observation because they can become dehydrated more quickly.

Ask whether your symptoms need testing, which treatment is suitable, when you can return to work or school, and whether vaccination is useful for future prevention after recovery.
