I just read a msm article on antibodies, focus on Lilly and regeneron of course, along with Prometheus/US Army collaboration, where they said nearly all mABs being studied, generate antibodies for a few weeks at most before crapping out, in medical parlance. I seem to recall that a few months ago LL was cited for restoration of the immunity system when squelching the cytokine storm, allowing the recovering host to start producing antibodies in normal fashion, restoring it to full strength in short order. Was that judgment made in error, do you know, or does LL's restoration of the immune system work that much better than competitors? I've never heard anything more about those claims.
