Genetically speaking, how similar are the sars-cov-2 variants to the “wild” virus? In terms of epitopes, how would that affect the immune systems ability to recognize wild vs mutated variants? Is it your understanding that the spike protein is a single epitope or is it made up of more epitopes?

Thank you. Do you have a study the shows this? Or maybe some keywords I could query to search for evidence of this?

Thank you! I should have specifically asked of you could put a % value on genetic similarity: ie the variants are 50%/75%/90% similar.
