Yes it will cause a false positive. The BCG Vaccine use's the actual virus itself to get the immune system to create the antibodies to the disease. The Mantoux Test is created by using the protien from the virus, instead of the actual virus. The Mantoux test reacts to the antibody that the body creates.
The BCG vaccine was discontinued for use by the FDA due to the high number of false positives vs the low number of actual cases being discovered.
You can also pop a positive test by the mere fact of being exposed to the disease. Keep in mind though, a postive test DOES NOT mean you have the disease, just the anti bodies in your immune system. This is why a chest XRay is done for a positive test.
Once you have tested positive and received a clear CXR, (Chest XRay), the only thing you need to do once a year is answer about 8 questions relating to whether or not you have experienced any symptoms of the disease, excessive nite sweats, mild grade temp for a long time and such.
It is recommended that you get your TB Skin Test at least once a year. Where I work as a Trauma Nurse...I get it every 6 months.
There are a number of sites w/ a lot of info on the rise of TB cases being seen. The best one I have found is Web MD.
