The "jab" is called a PPD and it tests for TB. If you've been exposed to TB you will have antibodies in your system. If you don't the test won't expose you. Don't worry about that. You only really need it once every few years and even that is stretching it. People like Nurses, Respiratory Therapists and certain specialties of doctors need to have it done more often so if they are exposed they can catch it before it has a chance to do damage. Or people that work with AIDS patients probably should have it done more often
