Obviously, I hope the plasma approach works, heavens knows we need any therapy that works. However, I will categorize this under the "I'll believe it when I see it" bucket. Allogeneic therapy has always been very very difficult to pull off. Dustin Hoffman made it look easy but that's the movies.
Also, I am not sure that people's resistance to this virus could be simplified by just the presence of a specific antibody. That's over simplifying the human's immune response system. I am not sure people should be assuming that after they get exposed to this virus and their immune system fought it off, that they are "scott free" and can return to normal activity. The science is too early to know if a person who fought off the virus could later on have problems when their immunity is depressed, for whatever reason. Again I hope I'm wrong.
Speaking of genetic make up, I was talking to a front line physician the other day and he explained that it is incredible the variance in terms of how people are affected by this virus. For some it is almost nothing, but for others (thankfully, so far, it's the minority) it is absolutely devastating. He was almost wondering if there is a physiological profile that is yet to be determined. Similar to BRCA and breast cancer for example. Perhaps there is a specific gene mutation present in certain people that makes them vulnerable to this virus. If we could find out what that profile is, we could identify who the high risk folks are and help control the carnage. One hypothesis I have heard is epithelial cell abnormality and degradation. Epithelial cells naturally degrades with age, I suppose correlating the virus impact with age.
In the meantime though, small molecule and easy to produce, remdesivir study ends today and analysis follows. Hopefully good news in a few days. Fingers crossed.
