Hepatitis B is a disease caused by the hepatitis B virus (HBV). This virus attacks the liver. The disease can cause:
HBV is spread through the blood or other body fluids of an infected person.
Most hepatitis B infections clear up without treatment. Others develop into chronic hepatitis B. This can lead to serious complications, even death.
The hepatitis B vaccine is produced by inserting a gene for HBV into yeast. The yeast is grown, harvested, and purified. The vaccine is given as an injection into the muscle. This is usually given in a series of 3-4 shots during a 6-month period.
Newborns routinely receive the first dose of the hepatitis B vaccine before leaving the hospital. Two more injections are given to all infants at:
Depending on the type of vaccine, some babies may receive 4 doses.
Children and teens (aged 18 years or younger) who have not been immunized as babies can also get the vaccine. For children aged 11-15 years, there is a two-dose series available, called Recombivax HB.
It is recommended that adults (aged 18 years or older) get vaccinated if they are at high risk for hepatitis B. High risk includes:
All vaccines are capable of causing serious problems, such as a severe allergic reaction.
Most people who get the hepatitis B vaccine do not have problems. Some may have mild problems, including soreness where the shot was given and fever.
