Can Accelerate: For those who need rapid immunity against hepatitis b--travelers about to embark, for example--immunity can be given with a quicker series of injections & a later booster at one year. Some schedules are not fda approved but include vaccination at day zero then days 7 & 21 from first dose. Other schedules include days 0, 10, & 21. Very good immunity at day 21. Also done with mixed hep b/hep a.

Depends: If you do not complete the 3 dose series the effectiveness may wain over time. Since it has only been available since 1986, it may take some time to see if it has a lifelong benefit.

What is in the hepatitis b vaccine? How does it work?

Proteins: It works by including one of the viral surface proteins. This causes one's immune system to react and create protective antibodies for the hepatitis b virus. It takes several of the vaccines to get the adequate amount of antibody necessary to protect from disease. Great Question!
