HIV testing and vaccination

Dec 8, 1998

Dear Doctor,

Three months ago, I exposed to the virus. I took Elisa test and the result was negative. But I took the test while being vaccinated Hepatite B. My questions are:

Does the vaccination alter my test result? Should I get retested? ( My doctor told me I was OK)

Thank you very much

Response from Dr. Holodniy

There is very little data published to know whether vaccination at the time of HIV exposure affects HIV antibody production. In my opinion, a person should be able to make antibodies to both viruses if they were exposed to both at the same time. If this was truly a "high risk" exposure, it is not unreasonable to get retested in 3 months. MH
