In brief: Hepatitis b vaccine
If you have completed the series whic is three shots.
Second given 1 month after the first one and third after 4 months of the second shot.So far it seems the immunity holds for life but it has still to be seen as Hepatitis B Vaccine was started only in sixties.Hepatitis vaccine does not stay in your system it produces antibodies to make you immune against hepatitis b virus and you do not get disea.
