Vaccination, false negative??
Jul 25, 2004
I was vaccinated for the Hep B virus about 1 year before my possible HIV exposure. Could this cause a false negative in the western blot and NAT tests for HIV? Also could I give HIV to another person even though I tested negative. I'm having a lot of the symptoms of HIV and I tested negative at 6 months. Please help me!!

Hepatitis B vaccination would not interfere with HIV testing results. If you are still concerned about HIV infection and your symptoms, I would simply discuss this further with your physician to see if any further testing is warranted (like a repeat HIV antibody or HIV RNA). Based on your exposure and timing of exposure, your physician can help you determine if you need further evaluation. Also it will be important to discuss your symptoms and have a physical exam. This would probably be very reassuring in the long run. Sometimes severe anxiety can also lead to many symptoms.
