Your symptoms came on too soon to be due to HIV. To my knowledge its rarely if ever as soon as 5 days, and anyway your symptoms are typical of a hundred different things all more common than HIV. And as you understand intellectually if not emotionally, your exposure was low risk.
But to your direct question, immunizations are not known to delay seroconversion or to have any effect on the reliability any HIV tests, including both PCR and antibody tests. You're home free. From a medical or risk assessment perspective, you don't really need another test at 6 weeks. But my guess is that you'll want to do it for the additional reassuance. You can count on a negative result.
Good luck-- HHH, MD
Thanks for your quick response. The intellectual/emotional battle is a theme I think most people on this forum might debate. I knew I was in a low risk enviroment, but still was shocked I started feeling bad, loosing weight(forgot to mention above that I lost six lbs in a week and a half.) and generally was positive I was HIV positive. It's amazing how professional opinions can make you feel instantly better. Keep up the great work.
