I had the third vaccine at a mass vaccination centre outside Edinburgh yesterday evening. The admin lady who checked my appointment said it was going to be Moderna so I showed her the copy of the Blood Cancer UK letter- she checked with her supervisor who said I must discuss it withe vaccinator. He read it carefully and said it was right but wrong as they recognised (presumably updated advice over the last fortnight) we had to have full doses and therefore were giving third vaccine patients the full Moderna dose. He also checked my drugs and spent time checking ruxolitinib for contra indications. This is just my experience.
They also did my husband as he was only 10 days short of six months and had already been out there for his flu one nearly a fortnight ago, though his second letter hadn't come. ( We were near closing time and I suspect there was an excess of vaccines).
I listened carefully and he definitely got half the dose that I did. We were lucky as it was a very efficient and caring experience, though apparently there had been two hour waits earlier as there was a shortage of vaccinators.
We had both had our flu vaccines earlier, but in the future if we have to have these again and together I would certainly have the flu one in my dominant arm as both our covid vaccine arms are much sorer!
