IIRC the virus was isolated last year, so wouldn't at least some antibodies have been identified by now? Or, it's just very common to have to start over?

Is it unusually difficult for this coronavirus? eg I've heard it's unusually large.

Antibodies have been identified by now. They are being tested as we speak. Coronavirus is not more difficult than any other target really. It just takes time.
