Just a quick question here. Are there any known effects of various immunizations on the HIV antibody tests? I am in the military and have had an onslaught of immunizations in the past year to include HepA, HepB, Influenza, IPV, Meningococcal, H1N1, PPD, and TDAP. They don't hold back on us these days. Just wondering if anyone has seen any studies involving any of these immunizations and HIV testing.
