I said usually family (not always), sometimes its a solicitor or friend who has power of attorney or state trustee. Regardless of who makes the decision, once made they need to accept risk they will be more vulnerable than their fellow residents who did get vaccinated.
I dont know why you want to argue about what was good news which was that those who got vaccinated and tested positive are asymptomatic, should be celebrating that news.
Way too much focus on the minority who havent availed themselves of vaccination that they are eligible for, which is contributing to unbalanced risk assessment, and a way too slow roadmap for fully vaccinated people not being locked down domestically.
