We don't have the annual flu vaccination and won't be again this year, we've never had it done. Jess has had swine flu and did okay, her readings were up a bit but nothing we couldn't cope with, no ketones and not badly unwell. It's a personal decision which only you can make. Jess managed okay getting through it but some people don't, you won't know how your child will be. I don't think diabetes is going to make it worse, just more difficult to manage but diabetes doesn't guarantee they will get it badly. I remember being afraid that Jess would get swine flu and her diabetes would certainly make her have it badly, that wasn't true. Her brother (non diabetic) came down with it two days after her and they were no different to each other in how it affected them. We had planned on getting her vaccinated but she came down with it before the vaccine was available, now I'm glad we didn't have it done, it really wasn't bad at all. I admit that I am uncomfortable with vaccines so naturally I prefer not to have it done unless it's absolutely necessary.
