Each CCG puts up information, the problem is that they've each changed approach a bit so there's a changing picture. Bolton for example had GP led early on at Health Centre and Social club, then added Etihad in Manchester for those who could travel, then got pop-up walk-in centres on 30th March and vaccine buses mid April. None of that tells you if people can walk there or have a good bus route, which seems to be the issue people have had with getting to sites.
My borough and in fact the CCG as whole has bigger sites that are all fairly decently located for spread and transport, but they just don't seem to move through the vaccinations. Low vaccination rates yet only called up when the national sites go live with the age and everyone we know has been keen to book, quite a few people have travelled out of the area to get vaccinated. People in their 40s had a 2 week wait for the local centre, why if take-up is low? I really don't understand why but suspect it's because we got pulled into SW London CCG who are a bit shit, the only explanation I've seen for anything being delayed was when I read they were having a push in Croydon and Croydon were getting walk-ins. Fair enough, but the whole region is behind on vaccination, if they booked and used up the vaccines at other sites sooner they could have ordered more, I haven't seen anything nationally to suggest they had to make everyone wait for Croydon to catch up before more doses would be released.
