Brief Answer:
Not needed...

Detailed Answer:
Hi,

As far as the latest guidelines, a booster dose is not recommended if you have taken the initial set of 3 doses as per schedule. However if you have any medical condition which compromises your immune competence, we might consider measuring your antibody levels (anti HBs antibody) and accordingly decide the need to revaccinate.

In all healthy individuals there is no real need to revaccinate.

Hope this helps. Let me know if you need clarifications.
