The hospital says, in that combination, he will be contageous for up to 3 weeks, so they plan to keep him in the Covid area of the hospital for at least 21 days, then possibly move him to another area of the hospital to finish recovery.

I would say something, but my input would be ignored. I would only come across as being a conspiracy theorist, and they would just go ahead with the program anyway, despite what WE all know will be the final result.

You could sneak some horse paste in when you visit and rub it on his gums when nobody is in the room and he's asleep. Of course if he squeals on you then you could find yourself arrested for assault (or murder if he ends up dying).
Unfortunately, best choice is to let him suffer the consequences of his own decisions.
