Hello and welcome to HCM,

The regime for hepatitis B virus which is followed most commonly is as follows:
Doses 0, 1 and 6 and and a booster dose within five years after the first dose.
The first dose is the 0 dose, 1st dose is taken at first month and 6th dose six months after the first dose.
The booster dose has to be taken within five years of the first dose.
This regime should be strictly followed and if the compliance is not good, the antibody titre may not be as expected.
The antibodies start rising after six months.
A booster dose potentates the antibody titres.
If the booster dose is not taken within five years, the effect of the vaccination starts weaning off.
Please confirm whether you have taken the doses at correct time.

Thanks and take care
