Antibodies are what your immune system develops in response to an infectious agent like a virus. These take several forms and act as your bodies defense against that germ. It can take 4-6 weeks or more for the immune system to develop measurable levels of antibodies after an exposure. What your chances are cannot be determined by the information posted.
