Hard one really. No idea how they got into this situation. Are they outspoken antivaxxers? Was he vaxxed? On time or both shots? We're they just mistrusting the emergency use of the vaccine?
But no matter what, if he is intubated since four weeks, he is on his way out and I would have done anything for my wife when she was on the edge of dying. The wife is in a situation where every little chance is giving her hope, no matter how ridiculous. This is about medical Ivermectin, not horse dewormer. If costs are covered, the hospital made sure it can't get sued and the man is on his last breaths anyway, the harm isn't really big, and no matter what happens, there is at least another clinical result that's showing how his condition went under the medication.
