According to the World Health Organisation, approximately 600,000 people die every year as a result of hepatitis B. The hepatitis B vaccine is 95% effective in preventing infection and its chronic consequences.
Immunisation requires three individual doses, administered by injection. The second injection is given 4 weeks after the first and the third injection needs to follow 5 months later.
Healthcare workers are advised to carry out a blood test after the immunisation is completed, to check whether the vaccination was successful. Travellers are at a lower risk of contracting hepatitis B and do not require a blood test.
Once you have completed the whole course, you are protected for 5 years.
The hepatitis B vaccine can cause mild side effects, such as redness and soreness at the injection site. Occasionally, patients feel tired within the first few days after the injection.
