My friend and husband have a son still living at home at 26 due to mental illness. They have both been fully vaccinated and both have medical conditions that make them vulnerable. However, the son refuses to be vaccinated. They asked their other son to try and persuade him to be vaccinated, but he continues to refuse. On the face of it, I would say I love you, but you have to move out under these circumstances, but it is highly unlikely they will do this. And no, he doesn’t have a needle phobia. He says it’s his right to say no. What would you do?
