destinyland notes a microbiology professor describing "Immunity on Demand" (or "Immunity 2.0") and wonders whether we could genetically engineer all the antibodies we need. "...there's a good chance this system, or something like it, will actually be in place within decades. Caltech scientists have already engineered stem cells into B cells that produce HIV-fighting antibodies — and an NIH researcher engineered T cells that recognize tumors which has already had promising clinical trials again skin cancer. Our best hope may be to cut out the middleman. Rather than merely hoping that the vaccine will indirectly lead to the antibody an individual needs, imagine if we could genetically engineer these antibodies and make them available as needed?"
