My sister had what was diagnosed as a chest infection a month before Christmas, antibiotics didn't touch it, got given more of the same, still no better, went downhill fast, she has to be careful, has got myasthenia gravis and can't have an awful lot of stuff normal folk would be given and that includes flu jab. Grandchildren had the nasal spray flu stuff and it seems passed the flu it on to her, as kiddies get a sort of live version of the flu prep. So she ended up being taken into hospital Christmas day, and linked up to an antibiotic drip that was safe for her while they tried to work out what was wrong, during this her kidneys failed so she was then taken to the renal ward, and after a week it was found she had pneumonia and kidney failure due to swine flu given to her most probably by the grandchildren. She came home again new year's eve and it will prob take her months to recover...
