I believe the antibody test from the doctor or from the blood bank tests for IGG or IGA antibodies only. These are the short term antibodies that your body produces during and after infection. They last about a month to six week after symptoms subside. The long term immunity is provided by the T-cells which the tests do not detect. So good idea to take the test, but a negative result doesn't mean you don't have immunity. People who are known to have had the symptoms and recovered will likely not test positive after a couple of months, even though they are likely immune. If you take the vaccine, your body will produce the IGG and IGA antibodies rapidly to defeat the perceived virus threat, and anytime in your life that you might be exposed to this or a similar virus these antibodies will be rapidly produced (at direction of the T-cells) to mop up any virus before it can cause symptoms.
