Hepatitis B Vaccine

Hepatitis B is a viral infection of the liver, transmitted through direct contact with the blood or body fluids of an infected person. It is found worldwide, with the highest infection rates in parts of East Asia, Sub-Saharan Africa, the Amazon, and some regions of Eastern and Central Europe, the Middle East, and the Indian subcontinent. Infection rates are lower in Western Europe and North America. If left untreated, it can lead to serious liver conditions such as cirrhosis, liver failure, or liver cancer. Vaccination is the most effective prevention method. 

The risk of Hepatitis B for travellers is generally low, but certain activities can increase the risk, especially in areas where the virus is more common. These include unprotected sex, occupational exposure to blood, sharing needles or undergoing medical/dental procedures with unsterile equipment, adopting children from high-risk countries, and long-term stays in affected areas. 

• Course: Usually 3 doses on the standard schedule.
• Schedule: First appointment, 1 month later and 6 months after the first dose. Accelerated schedules may require an additional dose.
• Protection and boosters: Completing the course provides long-term protection. Routine boosters are generally unnecessary for people with a healthy immune system. Blood tests or further doses may be appropriate for certain medical conditions or occupational risks.
