I know full well they are not the same. They are also guessing on Covid since no samples of the live virus exist and they are also guessing that the spike protein is the silver bullet.
This is false information. The virus has been isolated and has been cultured. Further, it's been directly imaged. There's actual pictures of it. And we have its complete genetic sequence. We know every protein - every amino acid - of every structure for the entire thing. There's no "guess" about the S-protein. It binds to cell surface receptors to pass through the cell membrane. Antibodies bind to the S-protein blocking its ability to enter cells.
There's not much we don't know about COVID-19 and the SARS-CoV-2 virus that causes it at this point. Claims to the contrary are uninformed fearmongering.
