The technique is rather old fashioned so far as treatment goes. I remember that the Chinese health care
workers who had recovered were donating blood for the plasma, for treatment, in hope that it would help make the cases less severe.
Sorry, but I do not know how successful this has been for treatment in China
at this time.
It is something all nations could try, but if the Chinese were unsuccesssful with it, it is unlikely to work
on other groups. Such an attempt would need both quick and easy testing, and some kind of double blind study to see to what extend such injections were successful against the corona virus' manifestations.

The thread will be closed if it gets political. Talk with your friends about the political things; write about them on other social media if you want to, but don't bring divisive political wrangling here.
