Let's start this out by reaffirming that I am not a doctor. I am not here to advocate for or against any particular medical decision or medical treatment. I do not know enough about biology or chemistry to advocate for anything other than a good night's sleep and the wellbeing that moderation has been known to produce, but since I have also disregarded both sleep and moderation from time to time, that makes me (at best) a hypocrite so take that particular medical advice with a grain of salt…just a grain, mind you. We wouldn't want to get the hypertension crowd riled.
There is a new study out by the British Medical Journal (BMJ) that links the Pandemrix flu vaccine with a sleep disorder known as narcolepsy – this condition apparently occurs primarily in children and young adults who have received the flu vaccine. Upon further research, the vaccine principally causes problems for people of European descent who are for some reason more genetically prone to narcolepsy in the first place.
