A member asked:

I got a complete b vaccine 5 years ago. can i have another one?

A doctor has provided 1 answer

Yes,but: It would likely not add much to your immunity. The full 3 dose primary series appears to be adequate for long term protection.An extra dose would not hurt you (it is a non-living vaccine) unless you had an allergy to one of the vaccines components. That would have shown up with the primary series.
