Travel Vaccination

Diphtheria Vaccine

A quick booster for travellers whose diphtheria protection has had time to fade.

What is diphtheria, and where does it still circulate?

Diphtheria is a bacterial infection that mainly affects the throat and airways, spread through close contact and respiratory droplets. Left untreated, it can cause breathing difficulties and, in severe cases, damage to the heart and nerves.

Routine childhood vaccination has made diphtheria rare in the UK, but immunity fades over time and the infection still circulates in parts of Africa, Asia, the Indian subcontinent, and Eastern Europe, particularly where vaccination coverage has dropped.

It has been ten years or more since your last diphtheria-containing vaccine.

Questions about the diphtheria vaccine

Didn't I already have this as a child?

Most people in the UK were vaccinated in childhood, but immunity fades over time. A booster is recommended roughly every ten years for travel to at-risk areas.

Is it given alongside other vaccines?

Yes, it's usually combined with tetanus and polio in a single three-in-one injection.

Are there any side effects?

Mild soreness at the injection site is common. Fever or a more general reaction is rare. Your clinician will talk you through what to expect.

What if I don't know my vaccination history?

That's fine. Your clinician can assess your risk and recommend a suitable course as a precaution.
