It's approved for certain diseases.  The virus is something else altogether, and we all know the FDA only approves things if you spend years and years in trials, and spend tons of $$ greasing their palms to get that approval.  They don't work FOR US, they work for themselves and against us as much as they can.  They can't outright approve this for the virus until they get the studies they want.  Won't it be great when the "compassionate use" will cure so many people?!
