Polio vaccination protects against a viral infection that can cause paralysis. It is part of the routine UK vaccination schedule, and a booster may be recommended before travelling to areas where polio is still found. A pre-travel consultation reviews your vaccination history to confirm whether a booster is advised.
What Is Polio?
Polio (poliomyelitis) is caused by a virus that spreads easily between people, usually through contact with the faeces of an infected person, or less commonly through coughs and sneezes. Most people have no symptoms, but in rare cases polio can affect the brain and nerves, causing paralysis, usually in the legs.
Who Should Consider Vaccination?
Most people in the UK have already received polio vaccination as part of the routine childhood schedule. A booster before travel is generally recommended if your last dose was more than 10 years ago and you are travelling to a country where polio is still found, such as parts of Afghanistan and Pakistan. Some countries require proof of vaccination for entry or exit.
Vaccination Schedule
The full routine UK schedule involves six doses given in childhood and adolescence as part of combined vaccines. For travellers, a single booster dose is usually sufficient if a top-up is needed, typically given as a combined vaccine alongside diphtheria and tetanus protection.
Certificate Requirements
Some countries require proof of polio vaccination, known as an International Certificate of Vaccination or Prophylaxis (ICVP), before you can enter or leave. Check requirements for your specific itinerary well in advance of travel.
