She is self mobile, but only for short distances. A wheelchair is better from the carer's point of view, a) because the vaccination centre is not the GP surgery but a much larger building and b) because she is blind she will not know where to go as she cannot be accompanied by my sister.
Also the issue of reading the disclaimer has still not gone away. The person my sister spoke to was non committal about whether a member of staff would read it to our Mum. My sister is of the view we have to get her in the door first. When arrangements are made for her injection this will be clarified.
Not being fully mobile is bit of a problem but not impossible to find a way round. The main issue is around consent if no-one is willing to explain ie read though the form with her. Before asking her to freely sign it then the giver has a problem any giver of any treatment has to ensure that it's done with informed consent. A HCP in this case has a problem as it's not clear if she has given it. So even if she can get though the door she my not get the vaccination anyway. I've check with Mrs 73 no legal issues or professional ones are stopping them reading it to her. Mrs 73 often reads things to patients that can't read. As long as they freely sign the form without any prompting or encouragement or force than it not an issue.
