When shoud I retake Vaccine of Hep(B) again ?!

[mr1981]

Hello!
I'd like to ask about something regarding Vaccine and in particular for Hep(B).  I took the three Vaccines of Hep(B) chronological in:

DD/MM/YY
13/11/2006 (The first satge of vaccine)
18/12/2006 (The second satge of vaccine)
18/6/2007 (The final stage of vaccine)

And in 18/11/2007 i tested for Hep(B) and the result was:
HBsAg :NON-Reactive
Anti-HBs :> 1000mIU/ML
Note: immune

I know that I have no HBs, but I am going to ask about when should I retake the three Vaccines again to be an immune one?
Or was those the three vaccines which I took enough for the next of 5 years? or even for ever?
Thanks a lot.

I am 26 yrs old when i was in grade 7, 13 years ago i had all three hep b immunizations, I am starting a course in November wich i needed blood work to show and prove my immunity and I am no longer immune these shots are suppose to last 20+ yrs 13 yrs later I have no immunity and i have to go pay $183 for hep a and b now shots to bring to my doctor to administer :(, so get your family doctor to take blood work and see if u are still immune check every couple of years so u know for sure

No, usually you do not need to retake the three shots.

Thanks for your help,
But when usually should I retake the three Vaccines "which I took before" again to saty an immune one?
Thanks again.

Most people do not need to be vaccinated again and remain immune for life.
