Hepatitis B is transmitted by direct contact with the blood or body fluids of an infected person. Not all infected persons have symptoms. There is no cure for hepatitis B, but it is preventable by the hepatitis B vaccine. The vaccine is given in the muscle of the upper arm. Three doses are given over a six-month period to provide complete protection.
Some people have a sore arm for several days.
The dose schedule is first dose, second dose one month later, and third dose six months after first dose.
