Diphtheria vaccination protects against a serious bacterial infection of the throat and respiratory system that can be fatal if untreated. It is recommended for travellers who are not fully vaccinated, particularly to regions with lower immunisation coverage. A pre-travel consultation checks your vaccination history against current UK schedules.
What Is Diphtheria?
Diphtheria is a bacterial infection that mainly affects the nose and throat, and can also affect the skin. It spreads through close contact with an infected person, such as coughing or sneezing, and can cause breathing difficulties, heart problems and nerve damage in severe cases. Diphtheria is rare in the UK due to routine childhood vaccination but still occurs in areas with lower vaccination coverage.
Who Should Consider Diphtheria Vaccination?
Travellers who have not completed a full UK vaccination schedule, or whose last booster was more than ten years ago, may be advised to have a diphtheria-containing booster before visiting regions where the disease is more common. This is usually combined with tetanus and polio vaccination.
Vaccination Schedule
In the UK, diphtheria vaccination is given as part of routine childhood immunisation, with boosters offered at preschool age and in adolescence. Travellers needing an update usually receive a single combined diphtheria, tetanus and polio booster, which provides protection for around ten years.
Symptoms to Be Aware Of
Symptoms of diphtheria include a sore throat, fever and a thick grey coating at the back of the throat. Anyone who develops these symptoms after travelling to an area with known diphtheria activity should seek prompt medical attention.
Frequently Asked Questions
Do I need a diphtheria booster before travelling?
This depends on your vaccination history. A pre-travel consultation reviews your records and advises whether a booster is needed for your destination.
Is the diphtheria vaccine given on its own?
No, it is usually given as a combined vaccine with tetanus and polio (Td/IPV) rather than as a single diphtheria vaccine.
How long does protection from a booster last?
A diphtheria-containing booster typically provides protection for around ten years, though your clinician will confirm this based on your history.
Is diphtheria still a risk for travellers?
Diphtheria is rare in the UK but outbreaks still occur in regions with lower vaccination coverage, making pre-travel assessment worthwhile.
Can children receive the diphtheria travel booster?
Yes, children can receive an updated booster if due, subject to clinical assessment of their vaccination history.
