Vaccinated for Hepatitis B as a baby but may be positive?! Please help ?
Like always I get tested for STDs very regularly. I haven’t had vaginal sex in over 2 years but have had oral sex back in February. My partner and I are really good friends and we are currently in that “talking stage” we haven’t done anything since that encounter back in February but we have opened mouth kissed. I got tested this week and my doctor informed me that I may be Hepatitis B positive but still have to do some labs to be sure. I have been vaccinated for this and have had all three doses so I’m really scared and confused as I thought that meant I would be protected against it. It has me thinking because I’m vaccinated for a lot of things like HPV being one of them and other hepatitis vaccines so does this mean even though I’ve been vaccinated for these things I could still get them? Everything else came back negative so honestly I’m so scared but any advice or information on this would be great.

The vaccine is not 100% effective and some people do not seroconvert meaning they don't become immune no matter how many shots they were or are given with that vaccine.
I am not too sure what your doctor means or the country you live in. In the US when hepatitis testing is done for hepatitis B there is a screening test and then a confirmatory test on all initial positive tests to make sure it isn't a false positive. When one gets a positive test result then it is positive and has been confirmed and the doctor does not need to do anything on his own as the initial results are not reported out until confirmed based on laboratory protocols.
If you live in another country then they might not confirm screening tests in which case a doctor might want a repeat with a more reliable test to confirm it.
The other possibility is a mixup on what he meant be hepatitis B positive. He might have meant that you are positive for the antibodies against hepatitis B which would make sense in someone who was vaccinated.
So what was positive is important for interpretation. There is a battery of hepatitis B testing.
