HBV is spread through the blood or other body fluids of an infected person.

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.
