What should you know about diphtheria typhoid vaccination?

Diphtheria is a bacterial infection that can produce a damaging toxin, while typhoid fever is linked to Salmonella Typhi and commonly spreads through contaminated food or water. Their vaccines train the immune system against different targets. A travel plan may therefore include typhoid protection alongside an up-to-date routine vaccination record.

Typhoid vaccines reduce risk but do not make food and water precautions unnecessary. Ask which product is suitable for your age, health, destination, and departure timing. See [Typhoid Fever](/conditions/typhoid-fever/) and [Inactivated Vaccine](/materials/inactivated-vaccine/).

Book a travel-health appointment early and share your itinerary, length of stay, activities, previous vaccines, allergies, pregnancy status, and medicines. The clinician can check whether typhoid vaccination is advised and whether your diphtheria-containing vaccines are current.

After vaccination, keep the record with your travel documents. Continue careful handwashing, choose safe food and water, and seek medical advice for fever or gastrointestinal illness during or after travel.

Get urgent help for breathing difficulty, facial or throat swelling, collapse, or a rapidly worsening allergic reaction after vaccination. During travel or after returning, seek prompt care for persistent fever, severe weakness, confusion, dehydration, or difficulty breathing.

Ask which diseases each planned vaccine covers, whether you need both typhoid and diphtheria protection, when doses should be given, what side effects to expect, and which food and water precautions fit your itinerary.
