PT, I admit there’s some risk probably in taking the vaccine just like anything but I think it’s more risky not to. I would tell your brother the truth and see what he says. SM is right that you could stay at a hotel to visit him if it comes to that. It’s a shame that he is changing for the worse. I am actually surprised at how many people divorce after retirement. When I think about it my ex has changed in many ways for the worse as he has aged. I was just dealing with it until the cheating. I am sorry you are going through this.
