Does a MMR vaccination or a TB test affect the HIV test?

Q: I took the MMR vaccination and a TB test (called the MT test) sometime last week. Will it have any affect on my HIV ELISA tests results, which I am going to take this week since the time difference between my HIV test and the MMR vaccination along with my TB test is going to be less then seven days?

A:A false-negative Mantoux test result occurs when (a) had MMR or OPV vaccination within the past month, (b) is under-nourished or recovering from a recent acute illness or (c) is HIV-positive, has cancer, is having treatments that suppress the immune system, or sometimes disseminated TB itself. Simultaneous administration of MMR vaccine and Mantoux test is OK. However, the HIV test should ideally be done after a month.
