DD (3) has been offered a swine flu jab, but I'm pretty sure she had swine flu last summer. Of course, because they weren't testing at the time, I've no idea whether she really did have it. I'm usually all for vaccinations, but I don't really want to put her through the trauma if she doesn't need it because she's already immune. Am waiting for a call-back from the nurse at my doctor's surgery, but just thought I'd ask: can they do retrospective testing to see whether you've had the illness and therefore won't need the jab?
