I agree with BC that we need to be testing these antibodies with much larger samples of negatives. They are widely available so should be feasible. 

I disagree with OF that these are pointless. One of the tricky things is that early in an epidemic is when you need the very best antibodies. In a later stage when many people have the disease, a test with 97% specificity is still a very useful one. And there's great reason to believe you would have some degree of immunity for some indeterminate time, though the exact nature of this immunity is still unknown.
