Hepatitis B is a viral infection that can cause serious, long lasting damage to the liver. It spreads through contact with blood and certain body fluids, which means travellers may be at risk through activities such as receiving medical or dental treatment abroad, tattooing, or unprotected sex. In parts of sub-Saharan Africa and Asia the virus is common in the general population.
The vaccine is given as a course of three injections. The standard schedule spreads doses over 6 months, but an accelerated schedule delivers all three doses within 3 weeks, making it a practical choice for people who book travel at relatively short notice. Over 90% of adults who complete the course develop strong immunity, and protection is expected to last for many years.
If you are travelling to a country where hepatitis B is widespread, or if your plans include activities with a potential exposure risk, it is worth discussing the vaccine at your travel consultation. Call us on 0161 437 2634 if you are unsure whether the course fits your travel dates.
