@FailForward this is known. Corticosteroids are powerfully antianflammitory, but they also suppress the immune system. A lot of the ARDS caused by COVID is by the immune system causing lung inflammation. It has been known this whole time that steroid use is a balancing act between symptom alleviation and immune system suppression.
@FailForward makes sense!
@Demosthenes I read about it in regular newspaper, but never stumbled upon a paper confirming it (not that I looked for it). I just want to keep a reference in this scrapbook of mine.
