LOL83001 -This news was really not unexpected in severe patients , this drug is an :
"Antiviral Antibody Cocktail "
It is two neutralizing antibodies , doing nothing else just neutralizing some virus. But with no effect on immune system.
So should be helpful at the beginning of the disease , and even then not always as a mono treatment.
We know what happened to our President,
He felt better after REGN , but in 1 and 2 days started to develop inflammation in his lungs with oxygen saturation going down to 93% , and required more treatment , in this situation he received steroid.
We know that viral load in covid is the highest in about 7-9 days and after that in sick people starts more aggressive immunological stage but viral load is going down, and very sick may not have any..
All imo..
