My adult sibling (aged 57) lives with our mum (aged 76) in my mum’s property. My sibling does not work and is refusing to be vaccinated now she has been called for their first dose. I am concerned about the risk she pose to my mum. My mum has said if she wishes not to be vaccinated then she must move out of her house. However I don’t think my mum will make her leave as she has no where else to go or enough money to live by herself. Any advice?? Many thanks
