Are you watching the progress (or the lack thereof) in this field?
I've been reading for a while about Polish company working on a cure for Covid based on convalescent plasma.
I know and heard about people being cured by the convalescent plasma therapy, but I also read about its shortcomings: requires two donors (persons recovered from covid) per patient - i.e. it's expensive, and it's difficult to estimate the efficacy of the treatment because the variability of plasma concentration in the donated blood - the doctors prefer to allocate scarce resources to cheaper and less doubtful options.
The Biomed folk developed a plasma-derived medicine in the form of an injection (doesn't require specialist administration, which generally increases the efficacy, especially in less developed countries), which has precise parameters (easy to test in trials) and serves 1000 patient with just 280 donors (as compared to 2 donors per patient in the case of the standard CT therapy). They are now starting the cure production (should be ready in 1.5 month) and next trials.
It's supposed to be tested as both a therapeutical and preventive medicine.
Perhaps a worthy investment too? (They grew 800%+ over the past 6 months, though.)
