1. I guess for smaller batches it is easier to develop the mRNA. Otherwise, we would have monoclonal antibodies and not a vaccine(the vaccine has other benefits, it trains the T-cells and the B cells remain dormant even after no abtibodies are detected in the blood). 2. The imune system knows all your protein already, t cells are evolved in the thymus gland, if they attack anything "self", they get destriyed.
