A combined vaccination that protects against diphtheria, polio and tetanus is routinely given to all children in the UK.

You should make sure you and your children are up-to-date with your routine vaccinations before travelling.

Further booster doses are usually only recommended if you’re going to visit parts of the world where diphtheria is widespread and your last vaccination dose was more than 10 years ago.

Diphtheria is more common in parts of the world where fewer people are vaccinated, such as:

• Africa
• Central and Southeast Asia
• South America
• Haiti
• Eastern Europe
• Russia

Additional doses of the vaccination are given in a single 3-in-1 Td/IPV (tetanus, diphtheria and polio) injection
