We have an elderly relative with a variety of serious health problems, including dementia which is now tipping over to a point of significant confusion, including confusion about who people are. He also has cardio-vascular problems. He is in and out of hospital. We have already made a decision against resuscitation or ventilation. Essentially those decisions boil down to an acknowledgement that his quality of life is deteriorating to a point where a sooner "natural" death will be kinder to him than a later one. The question hasn't actually arisen yet, but it occurs to me that it might well be inconsistent for him to be vaccinated against covid, or indeed flu. I don't know what the right answer is, or whether the medical profession will formally acknowledge that this is a legitimate decision along with non-resuscitation. Any thoughts?
