I had a sexual exposure 4years ago, and i tested for hiv through a 4th generation combo test 3 years later (8months ago) which was thankfully negative, roughly 3-5days before i did the test i had a Tetanus and diphtheria combined vaccine (DT VACCINE). My question is could the vaccine had any effect on the test and even caused a false-negative or can i rest easy knowing that my test was accurate?
accurate x
