A member asked:

My child vaccined for hep b when she born . she is now 8 years old doctor talk us to get hep b vaccine again ? why this happens

A doctor has provided 1 answer

Basics: The initial dose is recommended at birth. However a 2nd & sometimes a 3rd dose are part of the series. These boosters are meant to build on that initial dose & prolong protection for decades that would otherwise fail sooner.

I may have walked past and touched a downed bat with my sneaker. I don't think I had skin contact and didn't see the bat move when I was near it, but still worried I might not have noticed. Should I talk to my doctor about the rabies vaccine?

I had the hep b vaccine years apart from each other, my clinic, or doctors have never informed me of this, can I still be protected from hep b?
Had the hep b vaccine on 7/24, donated plasma in 7/26 test cane back inconclusive. My doc said he could do an immunity test but for me to wait 2-3 months? Im suppose to get my 2nd shot on 8/26. Do you agree? This is nerve racking
Why are doctors seeming so reluctant to give the hep b vaccine now?
Went & got the Hep b vaccine & 2 days later donated plasma & when they tested it, it came back false positive. My doc wanted me to wait a while to test me & I dont have Hep B. Will I never be able to donate blood? Even for a family member?
