Thanks for writing in.
The chances of post vaccination
antibody giving positive HIV test
is very rare.
Positive western blot confirms the HIV and it is usually very diagnostic.
To be further sure of HIV status you can get RNA PCR for HIV done .It is 100 % diagnostic and reliable test.
A visit to HIV specialist or dermatologist
will be helpful to take biopsy
and subsequent treatment.
Hope this helps.
