Yes, but they are mostly volunteers, so really can only repeat what they have been told. It's Chinese Whispers.
I'm not sure whether to request this or not. I don't fall on the severely compromised list, but I have a long history of vaccinations being effective for a much shorter time, or just not effective at all. For example, I've had the two whooping cough vaccinations that are meant to give immunity, and since then I've had whooping cough three times. Normally I wouldn't trouble the GP, but I'm on the list for surgery + stay in hospital in a few months. I don't know.
