Coronaviruses are called so because they look a certain way under an electron microscope. They don't necessarily have common proteins. So you point a does not stand. As for point b,due to the fact that antibodies are specialized and there are tons of viruses that cause the common cold, I wouldn't expect them to match or even exist at any given time in the bloodstream since they only last ~6m and after that memory takes the role of rapid production of new antibodies in case of a new infection.
- lbeltrame 6y agoThere is documented cross-reactivity in T-cell responses: individuals who had not come in contact with SARS-CoV-2 developed an immune reaction (T-cell based) against it. Whether this prevents infection (unlikely) or lessens the symptoms is still an open question. But the phenomenon exists.
