I am having trouble jumping on this particular bandwagon. Sorry.
There is nothing in the NHS leaflet we in Leeds received about the vaccination process saying that a person being inoculated has to be accompanied.
Also, my surgery has a contract with a local private hire firm for those facing difficulty in attending appointments. The patients still have to pay, but at a reduced rate. As I said on the other thread my inoculation centre is a two bus ride away so I would use the taxi service. My elderly neighbours, Mr and Mrs Old Couple in their 80s, did so on Wednesday when they went for their vaccinations.
