The hepatitis B vaccine is the mainstay of hepatitis B prevention. It is recommended that all
infants receive the hepatitis B vaccine.
The vaccine can be given as either three or four separate doses, as part of existing routine
immunization schedules.

at which a person becomes infected. Young children who become infected with the hepatitis B virus are the most likely to develop chronic infections 90% of infants.


Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem and the most serious type of viral hepatitis. It can cause chronic liver disease and puts people at high risk of death from cirrhosis of the liver and liver cancer. The hepatitis B virus is 50 to 100 times more infectious than HIV. Hepatitis B is an important occupational hazard for health workers.

Worldwide, an estimated two billion people ,one in 12 have been infected with the hepatitis B virus and more than 240 million have chronic (long-term) liver infections. About 600 000 people die every year due to the acute or chronic consequences of hepatitis B.Pakistan is currently home to around 15 to 18 million patients suffering from Hepatitis B. Almost every tenth person is carrying this deadly virus in his blood. Unfortunately, very few people in Pakistan have awareness about this disease and a very small percentage has been vaccinated against it and knows the importance of this vaccination.
A vaccine against hepatitis B has been available since 1982. It is the mainstay of hepatitis B prevention. Hepatitis B vaccine is 95% effective in preventing infection and its chronic consequences. This vaccine is a three shot series given over 6 months that can protect you for life. The vaccine is so effective at preventing HBV and liver cancer that it is called “the first anti-cancer vaccine” by the World Health Organization.
